* we don't actually care about the errstack here, it's an invalid signature ↵Paul Kehrer2018-07-101-2/+1
| | | | | | | | | | | | | | (#4325) * we don't actually care about the errstack here, it's an invalid signature We previously had no cases where we could error without getting errors on the error stack, but wycheproof contains test cases that can error without adding anything to the stack. Accordingly, we should clear the stack but raise InvalidSignature no matter what (rather than InternalError if we have no error msgs) * add a test

* fix encoding BMPString in x509 name entries (#4321)Paul Kehrer2018-07-091-2/+7
| | | | | | | | | | Previously we encoded them as UTF-8, but as best I can tell in reality a BMPString is fixed-width basic multilingual plane big endian encoding. This is basically UCS-2 (aka original Unicode). However, Python doesn't support UCS-2 encoding so we need to use utf_16_be. This means you can encode surrogate code points that are invalid in the context of what a BMPString is supposed to be, but in reality I strongly suspect the sane encoding ship has sailed and dozens if not hundreds of implementations both do this and expect other systems to handle their nonsense.
* Convert a pair of asserts to use openssl_assert (#4318)Alex Gaynor2018-07-091-2/+2
| | | We have an existence proof that the latter assertion can be triggered, and I bet the former can too.
* Future proofing use of the six python version constants (#4238)Eric Brown2018-05-141-2/+2
| | | | | | | | | | | | | | | * Future proofing use of the six python version constants After reading [1], noticed that cryptography uses a lot of if six.PY3 blocks. The issue with this is that whenever Python 4 is released, this code in the else block will be executed even though it was only intended for Python 2. [1] http://astrofrog.github.io/blog/2016/01/12/stop-writing-python-4-incompatible-code/ Signed-off-by: Eric Brown <browne@vmware.com> * Use not PY2 instead
* Validate the public/private halves of EC keys on import. (#4241)David Benjamin2018-05-141-3/+4
| | | | | | | | | | | | | | | | | | * Validate the public/private halves of EC keys on import. OpenSSL's API is a little finicky. If one sets the public key before the private key, it does not validate that they match. If set in the other order, it does validate this. In particular, KASValidityTest_ECCStaticUnified_NOKC_ZZOnly_init.fax describes error code 7 as: Result = F (7 - IUT's Static private key d changed-prikey validity) Reordering the two operations makes those tests to fail on key import, which is what CAVP appears to have intended. * Wrap to 79 rather than 80 columns
* Fix some stuttering. (#4240)David Benjamin2018-05-141-3/+0
| | | | This is a remnant of the function code checking when this logic looked at both encrypt/decrypt versions of this error code.

* backwards incompatible change to UniformResourceIdentifier (#3954)Paul Kehrer2017-10-102-5/+14
| | | | | | | | | | | | | | | * 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 Kehrer2017-10-102-5/+12

* Backwards incompatible change to DNSName (#3951)Paul Kehrer2017-10-102-3/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * 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 Kehrer2017-10-012-1/+9
| | | | | | | | | | | | | | | | | | | | | | | | * 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
* add ChaCha20 support (#3919)Paul Kehrer2017-09-282-1/+8

* both parse and encode the ASN1 string type for Name attributes (#3896)Paul Kehrer2017-09-253-18/+6
| | | | | | | | | | | | | | | * 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
* FreshestCRL extension support (#3937)Paul Kehrer2017-09-232-4/+16

* 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 Kehrer2017-09-131-1/+2
| | | | | 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.

* 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

| | | | | | | | | | * Test for leaking memory in EllipticCurvePublicNumbers.public_key() * Fix the memory leak As far as I can tell, from spelunking in the OpenSSL source (as you do), EC_KEY_set_public_key_affine_coordinates doesn't take ownership of "x" or "y". https://github.com/openssl/openssl/blob/master/crypto/ec/ecp_smpl.c#L362-L420 is the place in the source I found that actually uses "x" and "y". * Unused imports
