+
+2002-02-08 Werner Koch <wk@gnupg.org>
+
+ * random.c (add_randomness): Xor new data into the pool and not
+ just copy it. This avoids any choosen input attacks which are not
+ serious in our setting because an outsider won't be able to mix
+ data in and even then we keep going with a PRNG. Thanks to Stefan
+ Keller for pointing this out.
+
+2002-01-04 Werner Koch <wk@gnupg.org>
+
+ * pubkey.c (gcry_pk_genkey): Do not release skey - it is static.
+

+
+2001-12-18 Werner Koch <wk@gnupg.org>
+

+
+2001-11-20 Werner Koch <wk@gnupg.org>
+
+ * md.c (gcry_md_map_name): Lookup by OID if the the name begins

+
+2001-11-16 Werner Koch <wk@gnupg.org>
+
+ * md.c (gcry_md_info): New operator GCRYCTL_IS_ALGO_ENABLED.
+
+2001-11-07 Werner Koch <wk@gnupg.org>
+
+ * md.c (gcry_md_hash_buffer): Close the handle which was left open
+ for algorithms other than rmd160.
+
+2001-08-08 Werner Koch <wk@gnupg.org>
+
+ * rndw32.c (gather_random): Use toolhelp in addition to the NT
+ gatherer for Windows2000. Suggested by Sami Tolvanen.
+
+ * random.c (read_pool): Fixed length check, this used to be one

+ Reported by Marcus Brinkmann.
+
+2001-08-03 Werner Koch <wk@gnupg.org>
+
+ * cipher.c (cipher_encrypt, cipher_decrypt): Prepare to return

+ encryption modules.
+ (gcry_cipher_encrypt, gcry_cipher_decrypt): Return the error and

+ (gcry_cipher_ctl): Make sure that errors from setkey are returned.
+
+2001-08-02 Werner Koch <wk@gnupg.org>
+

+
+ * rndunix.c: Add a signal.h header to avoid warnings on Solaris 7

+ * tiger.c (print_abc,print_data): Removed.
+
+ * rijndael.c, des.c, blowfish.c, twofish.c, cast5.c, arcfour.c
+ (burn_stack): New. Add wrappers for most functions to be able to
+ call burn_stack after the function invocation. This methods seems
+ to be the most portable way to zeroise the stack used. It does
+ only work on stack frame based machines but it is highly portable
+ and has no side effects. Just setting the automatic variables at
+ the end of a function to zero does not work well because the
+ compiler will optimize them away - marking them as volatile would
+ be bad for performance.
+ * md5.c, sha1.c, rmd160.c, tiger.c (burn_stack): Likewise.
+ * random.c (burn_stack): New.
+ (mix_pool): Use it here to burn the stack of the mixblock function.

+ * rmd160.c (rmd160_final): Ditto.
+ * tiger.c (tiger_final): Ditto.
+
+ * blowfish.c (encrypt,do_encrypt): Changed name to do_encrypt to
+ avoid name clashes with an encrypt function in stdlib.h of
+ Dynix/PIX. Thanks to Gene Carter.
+ * elgamal.c (encrypt,do_encrypt): Ditto.
+
+ * twofish.c (gnupgext_enum_func): Use only when when compiled as a
+ module.
+ * rijndael.c (gnupgext_enum_func): Ditto.

+
+2000-11-14 Werner Koch <wk@gnupg.org>
+

+
+ (read_pool): Do an initial extra seeding when level 2 quality random
+ is requested the first time. This requestes at least POOLSIZE/2 bytes
+ of entropy. Compined with the seeding file this should make normal
+ random bytes cheaper and increase the quality of the random bytes
+ used for key generation.
+
+ * random.c (read_pool): Print a more friendly error message in
+ cases when too much random is requested in one call.
+
+ * random.c (fast_random_poll): Check whether RUSAGE_SELF is defined;
+ this is not the case for some ESIX and Unixware, although they have
+ getrusage().
+
+ * primegen.c (generate_elg_prime): All primes are now generated with
+ the lowest random quality level. Because they are public anyway we

+ * U S A G E
+ * ===========
+ *
+ * For DES or Triple-DES encryption/decryption you must initialize a proper
+ * encryption context with a key.
+ *
+ * A DES key is 64bit wide but only 56bits of the key are used. The remaining
+ * bits are parity bits and they will _not_ checked in this implementation, but
+ * simply ignored.
+ *
+ * For Triple-DES you could use either two 64bit keys or three 64bit keys.
+ * The parity bits will _not_ checked, too.
+ *
+ * After initializing a context with a key you could use this context to
+ * encrypt or decrypt data in 64bit blocks in Electronic Codebook Mode.
+ *
+ * (In the examples below the slashes at the beginning and ending of comments
+ * are omited.)
+ *
+ * DES Example
+ * -----------
+ * unsigned char key[8];
+ * unsigned char plaintext[8];
+ * unsigned char ciphertext[8];
+ * unsigned char recoverd[8];
+ * des_ctx context;
+ *
+ * * Fill 'key' and 'plaintext' with some data *
+ * ....
+ *
+ * * Set up the DES encryption context *
+ * des_setkey(context, key);
+ *
+ * * Encrypt the plaintext *
+ * des_ecb_encrypt(context, plaintext, ciphertext);
+ *
+ * * To recover the orginal plaintext from ciphertext use: *
+ * des_ecb_decrypt(context, ciphertext, recoverd);
+ *
+ *
+ * Triple-DES Example
+ * ------------------
+ * unsigned char key1[8];
+ * unsigned char key2[8];
+ * unsigned char key3[8];
+ * unsigned char plaintext[8];
+ * unsigned char ciphertext[8];
+ * unsigned char recoverd[8];
+ * tripledes_ctx context;
+ *
+ * * If you would like to use two 64bit keys, fill 'key1' and'key2'
+ * then setup the encryption context: *
+ * tripledes_set2keys(context, key1, key2);
+ *
+ * * To use three 64bit keys with Triple-DES use: *
+ * tripledes_set3keys(context, key1, key2, key3);
+ *
+ * * Encrypting plaintext with Triple-DES *
+ * tripledes_ecb_encrypt(context, plaintext, ciphertext);
+ *
+ * * Decrypting ciphertext to recover the plaintext with Triple-DES *
+ * tripledes_ecb_decrypt(context, ciphertext, recoverd);
+ *
+ *
+ * Selftest
+ * --------
+ * char *error_msg;
+ *
+ * * To perform a selftest of this DES/Triple-DES implementation use the
+ * function selftest(). It will return an error string if there are
+ * some problems with this library. *
+ *
+ * if ( (error_msg = selftest()) )
+ * {
+ * fprintf(stderr, "An error in the DES/Tripple-DES implementation occured: %s\n", error_msg);
+ * abort();
+ * }

+ * http://www.esat.kuleuven.ac.be/~bosselae/ripemd160.html

+ *
+ * Pseudo-code for RIPEMD-160
+ *
+ * RIPEMD-160 is an iterative hash function that operates on 32-bit words.
+ * The round function takes as input a 5-word chaining variable and a 16-word
+ * message block and maps this to a new chaining variable. All operations are
+ * defined on 32-bit words. Padding is identical to that of MD4.

+ * because it is only ever used that way and we can save some time by
+ * precomputing. Of course the main saving comes from precomputing the
+ * GF(2^8) multiplication involved in the MDS matrix multiply; by looking
+ * things up in these tables we reduce the matrix multiply to four lookups
+ * and three XORs. Semi-formally, the definition of these tables is:
+ * mds[0][i] = MDS (q1[i] 0 0 0)^T mds[1][i] = MDS (0 q0[i] 0 0)^T
+ * mds[2][i] = MDS (0 0 q1[i] 0)^T mds[3][i] = MDS (0 0 0 q0[i])^T
+ * where ^T means "transpose", the matrix multiply is performed in GF(2^8)
+ * represented as GF(2)[x]/v(x) where v(x)=x^8+x^6+x^5+x^3+1 as described
+ * by Schneier et al, and I'm casually glossing over the byte/word

+/* The exp_to_poly and poly_to_exp tables are used to perform efficient
+ * operations in GF(2^8) represented as GF(2)[x]/w(x) where
+ * w(x)=x^8+x^6+x^3+x^2+1. We care about doing that because it's part of the
+ * definition of the RS matrix in the key schedule. Elements of that field
+ * are polynomials of degree not greater than 7 and all coefficients 0 or 1,
+ * which can be represented naturally by bytes (just substitute x=2). In that
+ * form, GF(2^8) addition is the same as bitwise XOR, but GF(2^8)
+ * multiplication is inefficient without hardware support. To multiply
+ * faster, I make use of the fact x is a generator for the nonzero elements,
+ * so that every element p of GF(2)[x]/w(x) is either 0 or equal to (x)^n for
+ * some n in 0..254. Note that that caret is exponentiation in GF(2^8),
+ * *not* polynomial notation. So if I want to compute pq where p and q are
+ * in GF(2^8), I can just say:
+ * 1. if p=0 or q=0 then pq=0
+ * 2. otherwise, find m and n such that p=x^m and q=x^n
+ * 3. pq=(x^m)(x^n)=x^(m+n), so add m and n and find pq
+ * The translations in steps 2 and 3 are looked up in the tables
+ * poly_to_exp (for step 2) and exp_to_poly (for step 3). To see this
+ * in action, look at the CALC_S macro. As additional wrinkles, note that
+ * one of my operands is always a constant, so the poly_to_exp lookup on it
+ * is done in advance; I included the original values in the comments so
+ * readers can have some chance of recognizing that this *is* the RS matrix
+ * from the Twofish paper. I've only included the table entries I actually
+ * need; I never do a lookup on a variable input of zero and the biggest
+ * exponents I'll ever see are 254 (variable) and 237 (constant), so they'll
+ * never sum to more than 491. I'm repeating part of the exp_to_poly table
+ * so that I don't have to do mod-255 reduction in the exponent arithmetic.
+ * Since I know my constant operands are never zero, I only have to worry
+ * about zero values in the variable operand, and I do it with a simple
+ * conditional branch. I know conditionals are expensive, but I couldn't
+ * see a non-horrible way of avoiding them, and I did manage to group the
+ * statements so that each if covers four group multiplications. */

+ around to make the function more robust.
+
+2002-02-08 Werner Koch <wk@gnupg.org>
+
+ * random.c (add_randomness): Xor new data into the pool and not
+ just copy it. This avoids any choosen input attacks which are not
+ serious in our setting because an outsider won't be able to mix
+ data in and even then we keep going with a PRNG. Thanks to Stefan
+ Keller for pointing this out.
+
+2002-01-04 Werner Koch <wk@gnupg.org>
+
+ * pubkey.c (gcry_pk_genkey): Do not release skey - it is static.
+

+
+2001-12-18 Werner Koch <wk@gnupg.org>
+

+
+2001-11-20 Werner Koch <wk@gnupg.org>
+
+ * md.c (gcry_md_map_name): Lookup by OID if the the name begins
+ with a digit.

+
+2001-11-16 Werner Koch <wk@gnupg.org>
+
+ * md.c (gcry_md_info): New operator GCRYCTL_IS_ALGO_ENABLED.
+
+2001-11-07 Werner Koch <wk@gnupg.org>
+
+ * md.c (gcry_md_hash_buffer): Close the handle which was left open
+ for algorithms other than rmd160.
+
+2001-08-08 Werner Koch <wk@gnupg.org>
+
+ * rndw32.c (gather_random): Use toolhelp in addition to the NT
+ gatherer for Windows2000. Suggested by Sami Tolvanen.
+
+ * random.c (read_pool): Fixed length check, this used to be one

+ Reported by Marcus Brinkmann.
+
+2001-08-03 Werner Koch <wk@gnupg.org>
+
+ * cipher.c (cipher_encrypt, cipher_decrypt): Prepare to return

+ encryption modules.
+ (gcry_cipher_encrypt, gcry_cipher_decrypt): Return the error and

+ (gcry_cipher_ctl): Make sure that errors from setkey are returned.
+
+2001-08-02 Werner Koch <wk@gnupg.org>
+

+
+ * rndunix.c: Add a signal.h header to avoid warnings on Solaris 7

+ * tiger.c (print_abc,print_data): Removed.
+
+ * rijndael.c, des.c, blowfish.c, twofish.c, cast5.c, arcfour.c
+ (burn_stack): New. Add wrappers for most functions to be able to
+ call burn_stack after the function invocation. This methods seems
+ to be the most portable way to zeroise the stack used. It does
+ only work on stack frame based machines but it is highly portable
+ and has no side effects. Just setting the automatic variables at
+ the end of a function to zero does not work well because the
+ compiler will optimize them away - marking them as volatile would
+ be bad for performance.
+ * md5.c, sha1.c, rmd160.c, tiger.c (burn_stack): Likewise.
+ * random.c (burn_stack): New.
+ (mix_pool): Use it here to burn the stack of the mixblock function.

+ for more than 512MB of input.
+ * sha1.c (sha1_final): Ditto.
+ * rmd160.c (rmd160_final): Ditto.
+ * tiger.c (tiger_final): Ditto.
+
+ * blowfish.c (encrypt,do_encrypt): Changed name to do_encrypt to
+ avoid name clashes with an encrypt function in stdlib.h of
+ Dynix/PIX. Thanks to Gene Carter.
+ * elgamal.c (encrypt,do_encrypt): Ditto.
+
+ * twofish.c (gnupgext_enum_func): Use only when when compiled as a
+ module.
+ * rijndael.c (gnupgext_enum_func): Ditto.

+
+2000-11-14 Werner Koch <wk@gnupg.org>
+

+
+ (read_pool): Do an initial extra seeding when level 2 quality random
+ is requested the first time. This requestes at least POOLSIZE/2 bytes
+ of entropy. Compined with the seeding file this should make normal
+ random bytes cheaper and increase the quality of the random bytes
+ used for key generation.
+
+ * random.c (read_pool): Print a more friendly error message in
+ cases when too much random is requested in one call.
+
+ * random.c (fast_random_poll): Check whether RUSAGE_SELF is defined;
+ this is not the case for some ESIX and Unixware, although they have
+ getrusage().
+
+ * primegen.c (generate_elg_prime): All primes are now generated with
+ the lowest random quality level. Because they are public anyway we

+ * U S A G E
+ * ===========
+ *
+ * For DES or Triple-DES encryption/decryption you must initialize a proper
+ * encryption context with a key.
+ *
+ * A DES key is 64bit wide but only 56bits of the key are used. The remaining
+ * bits are parity bits and they will _not_ checked in this implementation, but
+ * simply ignored.
+ *
+ * For Triple-DES you could use either two 64bit keys or three 64bit keys.
+ * The parity bits will _not_ checked, too.
+ *
+ * After initializing a context with a key you could use this context to
+ * encrypt or decrypt data in 64bit blocks in Electronic Codebook Mode.
+ *
+ * (In the examples below the slashes at the beginning and ending of comments
+ * are omited.)
+ *
+ * DES Example
+ * -----------
+ * unsigned char key[8];
+ * unsigned char plaintext[8];
+ * unsigned char ciphertext[8];
+ * unsigned char recoverd[8];
+ * des_ctx context;
+ *
+ * * Fill 'key' and 'plaintext' with some data *
+ * ....
+ *
+ * * Set up the DES encryption context *
+ * des_setkey(context, key);
+ *
+ * * Encrypt the plaintext *
+ * des_ecb_encrypt(context, plaintext, ciphertext);
+ *
+ * * To recover the orginal plaintext from ciphertext use: *
+ * des_ecb_decrypt(context, ciphertext, recoverd);
+ *
+ *
+ * Triple-DES Example
+ * ------------------
+ * unsigned char key1[8];
+ * unsigned char key2[8];
+ * unsigned char key3[8];
+ * unsigned char plaintext[8];
+ * unsigned char ciphertext[8];
+ * unsigned char recoverd[8];
+ * tripledes_ctx context;
+ *
+ * * If you would like to use two 64bit keys, fill 'key1' and'key2'
+ * then setup the encryption context: *
+ * tripledes_set2keys(context, key1, key2);
+ *
+ * * To use three 64bit keys with Triple-DES use: *
+ * tripledes_set3keys(context, key1, key2, key3);
+ *
+ * * Encrypting plaintext with Triple-DES *
+ * tripledes_ecb_encrypt(context, plaintext, ciphertext);
+ *
+ * * Decrypting ciphertext to recover the plaintext with Triple-DES *
+ * tripledes_ecb_decrypt(context, ciphertext, recoverd);
+ *
+ *
+ * Selftest
+ * --------
+ * char *error_msg;
+ *
+ * * To perform a selftest of this DES/Triple-DES implementation use the
+ * function selftest(). It will return an error string if there are
+ * some problems with this library. *
+ *
+ * if ( (error_msg = selftest()) )
+ * {
+ * fprintf(stderr, "An error in the DES/Tripple-DES implementation occured: %s\n", error_msg);
+ * abort();
+ * }

+ Although algorithm self-tests are usually implemented in the module

+ HMAC is implemnetd on a higher level using a special feature of the
+ gcry_md_ functions. It would be possible to do this also in the
+ digest algorithm modules, but that would blow up the code too much
+ and spread the hmac tests over several modules.
+

+ * RIPEMD-160 is not patented, see (as of 25.10.97)
+ * http://www.esat.kuleuven.ac.be/~bosselae/ripemd160.html
+ * Note that the code uses Little Endian byteorder, which is good for
+ * 386 etc, but we must add some conversion when used on a big endian box.
+ *
+ *
+ * Pseudo-code for RIPEMD-160
+ *
+ * RIPEMD-160 is an iterative hash function that operates on 32-bit words.
+ * The round function takes as input a 5-word chaining variable and a 16-word
+ * message block and maps this to a new chaining variable. All operations are
+ * defined on 32-bit words. Padding is identical to that of MD4.

+/* These MDS tables are actually tables of MDS composed with q0 and q1,
+ * because it is only ever used that way and we can save some time by
+ * precomputing. Of course the main saving comes from precomputing the
+ * GF(2^8) multiplication involved in the MDS matrix multiply; by looking
+ * things up in these tables we reduce the matrix multiply to four lookups
+ * and three XORs. Semi-formally, the definition of these tables is:
+ * mds[0][i] = MDS (q1[i] 0 0 0)^T mds[1][i] = MDS (0 q0[i] 0 0)^T
+ * mds[2][i] = MDS (0 0 q1[i] 0)^T mds[3][i] = MDS (0 0 0 q0[i])^T
+ * where ^T means "transpose", the matrix multiply is performed in GF(2^8)
+ * represented as GF(2)[x]/v(x) where v(x)=x^8+x^6+x^5+x^3+1 as described
+ * by Schneier et al, and I'm casually glossing over the byte/word
+ * conversion issues. */

+/* The exp_to_poly and poly_to_exp tables are used to perform efficient
+ * operations in GF(2^8) represented as GF(2)[x]/w(x) where
+ * w(x)=x^8+x^6+x^3+x^2+1. We care about doing that because it's part of the
+ * definition of the RS matrix in the key schedule. Elements of that field
+ * are polynomials of degree not greater than 7 and all coefficients 0 or 1,
+ * which can be represented naturally by bytes (just substitute x=2). In that
+ * form, GF(2^8) addition is the same as bitwise XOR, but GF(2^8)
+ * multiplication is inefficient without hardware support. To multiply
+ * faster, I make use of the fact x is a generator for the nonzero elements,
+ * so that every element p of GF(2)[x]/w(x) is either 0 or equal to (x)^n for
+ * some n in 0..254. Note that that caret is exponentiation in GF(2^8),
+ * *not* polynomial notation. So if I want to compute pq where p and q are
+ * in GF(2^8), I can just say:
+ * 1. if p=0 or q=0 then pq=0
+ * 2. otherwise, find m and n such that p=x^m and q=x^n
+ * 3. pq=(x^m)(x^n)=x^(m+n), so add m and n and find pq
+ * The translations in steps 2 and 3 are looked up in the tables
+ * poly_to_exp (for step 2) and exp_to_poly (for step 3). To see this
+ * in action, look at the CALC_S macro. As additional wrinkles, note that
+ * one of my operands is always a constant, so the poly_to_exp lookup on it
+ * is done in advance; I included the original values in the comments so
+ * readers can have some chance of recognizing that this *is* the RS matrix
+ * from the Twofish paper. I've only included the table entries I actually
+ * need; I never do a lookup on a variable input of zero and the biggest
+ * exponents I'll ever see are 254 (variable) and 237 (constant), so they'll
+ * never sum to more than 491. I'm repeating part of the exp_to_poly table
+ * so that I don't have to do mod-255 reduction in the exponent arithmetic.
+ * Since I know my constant operands are never zero, I only have to worry
+ * about zero values in the variable operand, and I do it with a simple
+ * conditional branch. I know conditionals are expensive, but I couldn't
+ * see a non-horrible way of avoiding them, and I did manage to group the
+ * statements so that each if covers four group multiplications. */

+ * state.
+ *
+ * Because the output buffer is used as the workspace, streams encoded using
