* Make the docs clearer on why truncated tags are a bad idea (#4312)Alex Gaynor2018-07-061-4/+4
| | | | | | * Make the docs clearer on why truncated tags are a bad idea * clarify
* Add OID for RSASSA-PSS X.509 signature algorithm (RFC 4055) (#4294)Marti Raudsepp2018-06-291-0/+9
| | | | | | | | | | | | In 2005, IETF devised a more secure padding scheme to replace PKCS #1 v1.5. To make sure that nobody can easily support or use it, they mandated lots of complicated parameters in the certificate, unlike any other X.509 signature scheme. https://tools.ietf.org/html/rfc4055 `_SIG_OIDS_TO_HASH` and `Certificate.signature_hash_algorithm` cannot be supported as-is, because the hash algorithm is defined in the signature algorithm parameters, not by the OID itself.
* Add py37 (#4298)Paul Kehrer2018-06-271-1/+1
| | | | | | | | | | | | | | * test against python 3.7 for windows * update docs to say we test on 3.7 * more succinct * maybe make this actually work. * link properly * moar changes

* Make AuthorityKeyIdentifier docs reflect reality (#4252)Thom Dixon2018-05-181-1/+1
| | | The `AuthorityKeyIdentifier.authority_cert_issuer` docs state that it returns a `Name` instance, but it [actually returns a list of `GeneralName` instances or `None`](https://github.com/pyca/cryptography/blob/master/src/cryptography/x509/extensions.py#L157).
* remove block size as a required part of HashAlgorithm (#4249)Paul Kehrer2018-05-161-6/+0
| | | | | | Internal block size isn't a particularly useful piece of information and constructions like SHA3 make it even harder to determine what that really means. Accordingly, we're removing it from the interface (but leaving it on all existing hashes)
* Add SHA512/224 and SHA512/256 test vectors from NIST CAVP (#4237)Paul Kehrer2018-05-141-1/+1

* Add support for extracting timestamp from a Fernet token (#4229)Paul Kehrer2018-05-121-0/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * Add API for retrieving the seconds-to-expiry for the token, given a TTL. * Process PR feedback: * Do compute the TTL, but just the age of the token. The caller can decided what to do next. * Factored out the HMAC signature verification to a separate function. * Fixed a copy&paste mistake in the test cases * Tests cleanup. * `struct` no longer needed * Document `def age()` * typo in `age()` documentation * token, not data * remove test for TTL expiry that is already covered by the parameterized `test_invalid()`. * let's call this extract_timestamp and just return timestamp * review comments * it's UNIX I know this

|
* Don't use whirlpool as an example (#4053)Alex Gaynor2017-12-111-1/+1
| | | | | Both because it's weirdo crypto, but also because we don't even support it. Adhere to our documented policy of using good crypto for all examples

* Update docs and changelog for URI, RFC822Name, and DNSName (#3955)Paul Kehrer2017-10-113-57/+44
| | | | | | | | | | | | | | | | * Update docs and changelog for URI, RFC822Name, and DNSName As of 2.1 we want users to pass A-label strings, but we still accept U-label strings and auto-encode on their behalf (with a deprecation warning). However, we do not return U-label in the value attribute so we are making a backwards incompatible change for users that utilize internationalized domain names. * language updates * add presentational to the word list * the linux dictionary is pathetic
* let's talk about bits baby (#3956)Paul Kehrer2017-10-118-57/+71

* Backwards incompatible change to DNSName (#3951)Paul Kehrer2017-10-101-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * 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 utf8 DNSName x509 vector (#3952)Paul Kehrer2017-10-091-0/+2

* disable smart quotes in sphinx to workaround a spellchecker issue (#3946)Paul Kehrer2017-10-031-0/+2
| | | | This makes it so we don't have to pin sphinx while we wait for sphinxcontrib-spelling to properly handle smart quotes
* Add support for AES XTS (#3900)Paul Kehrer2017-10-012-0/+43
| | | | | | | | | | | | | | | | | | | | | | | | * 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
