* Import idna lazily to reduce our memory consumption (#4601)Alex Gaynor2018-11-231-2/+12
| | | We only use idna in deprecated paths at this point, so we shouldn't make people pay for it.
* Remove unnecessary use of six.binary_type (#4569)Jon Dufresne2018-11-111-1/+1
| | | | | All supported Pythons have type bytes. On Python 2, it is an alias of str, same as six.binary_type. Makes the code slightly more forward compatible and removes some indirection.

| | | | | | | | | | | | | | * Add eq/ne/hash to PrecertificateSignedCertificateTimestamps This requires adding it to SignedCertificateTimestamps as well * slightly more consistent * right, these need to be conditional * compare by signature * don't use private API

* Make RelativeDistinguishedName preserve attribtue order (#4306)Marti Raudsepp2018-07-091-3/+8
| | | | Duplicate attributes now raise an error instead of silently discarding duplicates.
* Add OID for RSASSA-PSS X.509 signature algorithm (RFC 4055) (#4294)Marti Raudsepp2018-06-292-0/+3
| | | | | | | | | | | | 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.
* adding name so that 1.3.6.1.4.1.11129.2.4.2 is no longer and 'Unknown OID' ↵Joshua Crowgey2018-05-071-0/+3

* Revert "don't allow GeneralNames to be an empty list (#4128)" (#4161)Alex Gaynor2018-03-201-3/+0
| | | | | This breaks the urllib3 tests, as well as several in-the-wild certs This reverts commit 388d1bd3e9cd953fcc948edbc152d5d140c87eb8.
* don't allow GeneralNames to be an empty list (#4128)Paul Kehrer2018-03-051-0/+3

* Fix ASN1 string type encoding for several Name OIDs (#4035)Paul Kehrer2017-11-301-7/+15
| | | | | | | | | | | | | | | | | | | * Fix ASN1 string type encoding for several Name OIDs When we changed over to the new type encoding system we didn't verify that the new code exactly matched the ASN1 string types that OpenSSL was previously choosing. This caused serialNumber, dnQualifier, emailAddress, and domainComponent to change from their proper encodings to UTF8String as of version 2.1. Now we check to see if there's a sentinel value (indicating no custom type has been passed) and then check if the OID has a different default than UTF8. If it does, we set it. This PR also adds tests for the ASN1 string type of ever supported NameOID. * review feedback

* backwards incompatible change to UniformResourceIdentifier (#3954)Paul Kehrer2017-10-101-56/+19
| | | | | | | | | | | | | | | * 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 Kehrer2017-10-101-42/+20

* Backwards incompatible change to DNSName (#3951)Paul Kehrer2017-10-101-48/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * 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
* both parse and encode the ASN1 string type for Name attributes (#3896)Paul Kehrer2017-09-251-5/+41
| | | | | | | | | | | | | | | * 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

* 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.
