* backwards incompatible change to UniformResourceIdentifier (#3954)Paul Kehrer2017-10-103-61/+33
| | | | | | | | | | | | | | | * backwards incompatible change to UniformResourceIdentifier During this release cycle we decided to officially deprecate passing U-labels to our GeneralName constructors. At first we tried changing this in a purely backwards compatible way but get_values_for_type made that untenable. This PR modifies URI to accept two types: U-label strings (which raises a deprecation warning) and A-label strings (the new preferred type). There is also a constructor for URI that bypasses validation so we can parse garbage out of certificates (and round trip it if necessary) * nonsense empty commit 2.6 and codecov are the worst
* backwards incompatible change to RFC822Name (#3953)Paul Kehrer2017-10-103-47/+32

* Backwards incompatible change to DNSName (#3951)Paul Kehrer2017-10-103-51/+30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * Backwards incompatible change to DNSName During this release cycle we decided to officially deprecate passing U-labels to our GeneralName constructors. At first we tried changing this in a purely backwards compatible way but get_values_for_type made that untenable. This PR modifies DNSName to take three different types. U-label strings (which raises a deprecation warning), A-label strings (the new preferred type), and bytes (which are assumed to be decodable to unicode strings). The latter, while supported, is primarily intended for use by our parser and allows us to return the actual encoded data in a certificate even if it has not been properly encoded to A-label before the certificate is created. (Of course, if the certificate contains invalid utf8 sequences this will still fail, but let's handle one catastrophic failure at a time). * coverage * don't delete that asterisk from a test. it does things. * no bytes in DNSName. Private constructor for bypassing validation * test unicode in dnsname (yuck) * fix docs * empty commit, you disappoint me codecov * CI is the worst
* Add support for AES XTS (#3900)Paul Kehrer2017-10-014-9/+63
| | | | | | | | | | | | | | | | | | | | | | | | * Add support for AES XTS We drop the non-byte aligned test vectors because according to NIST http://csrc.nist.gov/groups/STM/cavp/documents/aes/XTSVS.pdf "An implementation may support a data unit length that is not a multiple of 8 bits." OpenSSL does not support this, so we can't use those test vectors. * fix docs and pep8 * docs fix * the spellchecker is so frustrating * add note about AES 192 for XTS (it's not supported) * docs work * enforce key length on ECB mode in AES as well (thanks XTS) * a few more words about why we exclude some test vectors for XTS
* Declare that 2.1 is the last version to support Python 2.6 (#3944)Alex Gaynor2017-10-011-1/+1
| | | | | | * Declare that 2.1 is the last version to support Python 2.6 * It's the Final Countdown!
* add ChaCha20 support (#3919)Paul Kehrer2017-09-283-1/+32
| | | | | | | | | | * add ChaCha20 support * review feedback * 256 divided by 8 is what again? * ...
* Expose FIPS funcs for OpenSSL. (#3939)Scott Sturdivant2017-09-273-0/+37
| | | | | | | | | | | | | * Expose FIPS funcs for OpenSSL. * Remove FIPS customization / conditionals. It seems that the FIPS functions are always defined, regardless of if the FIPS module is present. * Do not include FIPS_selftest_check func. * Libressl does not have FIPS.
* both parse and encode the ASN1 string type for Name attributes (#3896)Paul Kehrer2017-09-254-23/+47
| | | | | | | | | | | | | | | * both parse and encode the ASN1 string type for Name attributes Previously cryptography encoded everything (except country names) as UTF8String. This caused problems with chain building in libraries like NSS where the subject and issuer are expected to match byte-for-byte. With this change we now parse and store the ASN1 string type as a private _type in NameAttribute. We then use this to encode when issuing a new certificate. This allows the CertificateBuilder to properly construct an identical issuer and fixes the issue with NSS. * make the sentinel private too

* remove u-label conversion during general name decode (#3905)Paul Kehrer2017-09-131-49/+4
| | | | We support directly passing bytes now and these code paths are duplicated in the deprecated value attributes.
* fix a bug with URI value when parsing a string with no hostname (#3909)Paul Kehrer2017-09-132-2/+4
| | | | | strings of the form "scheme:///anything" would incorrectly have two slashes dropped. This is fixed in two code paths in this PR but one of those code paths will be entirely removed in a followup PR.
* implement __hash__ on all GeneralName types (#3907)Paul Kehrer2017-09-131-2/+17
| | | Needed to implement __hash__ on AuthorityKeyIdentifier
* compare against bytes values, not the U-label decoded ones (#3906)Paul Kehrer2017-09-121-2/+2
| | | | We need to add one small test to cover a case that is no longer covered with this switch.
* refactor AES keywrap into a wrap core and unwrap core (#3901)Paul Kehrer2017-09-111-23/+30
| | | | | | | | * refactor AES keywrap into a wrap core and unwrap core This refactor makes adding AES keywrap with padding much simpler. * remove an unneeded arg

* add blake2b/blake2s support for hmac (#3873)Paul Kehrer2017-08-221-4/+3
| | | | | | | | | | * add blake2b/blake2s support for hmac This was a bug, but it turns out the noise protocol suggests using the HMAC construction with BLAKE2 (rather than BLAKE2's own keyed functionality) for a few reasons, so we should support it. * actually test the thing
* Remove branches for 1.0.2 betas. (#3870)Alex Gaynor2017-08-203-8/+6
| | | There's no sense in which we actually support them

* Fix weak linking of getentropy when compiling on older macOS (#3841)Paul Kehrer2017-08-031-0/+3
| | | | | | | | | | | | | * Fix weak linking of getentropy when compiling on older macOS We use weak linking in macOS to determine if the getentropy symbol is available. However, to do that we need to have a declaration that states the function is __attribute((weak_import)) at compile time. On macOS 10.12 this is provided in sys/random.h, but on older macOS the declaration doesn't exist at all, so we need to forward declare it ourselves. * update a comment and a style nit
