* Fixes #4734 -- Deal with deprecated things (#4736)Alex Gaynor2019-01-232-27/+6
| | | | | | | | | | * Fixes #4734 -- Deal with deprecated things - Make year based aliases of PersistentlyDeprecated so we can easily assess age - Removed encode/decode rfc6979 signature - Removed Certificate.serial * Unused import
* allow asn1 times of 1950-01-01 and later. (#4728)Paul Kehrer2019-01-223-8/+37
| | | | | | | | * allow asn1 times of 1950-01-01 and later. * add a test * pretty up the test
* allow 32-bit platforms to encode certs with dates > unix epoch (#4727)Paul Kehrer2019-01-211-8/+13
| | | | | | | | | | | | | | | | | Previously we used unix timestamps, but now we are switching to using ASN1_TIME_set_string and automatically formatting the string based on the year. The rule is as follows: Per RFC 5280 (section 4.1.2.5.), the valid input time strings should be encoded with the following rules: 1. UTC: YYMMDDHHMMSSZ, if YY < 50 (20YY) --> UTC: YYMMDDHHMMSSZ 2. UTC: YYMMDDHHMMSSZ, if YY >= 50 (19YY) --> UTC: YYMMDDHHMMSSZ 3. G'd: YYYYMMDDHHMMSSZ, if YYYY >= 2050 --> G'd: YYYYMMDDHHMMSSZ 4. G'd: YYYYMMDDHHMMSSZ, if YYYY < 2050 --> UTC: YYMMDDHHMMSSZ Notably, Dates < 1950 are not valid UTCTime. At the moment we still reject dates < Jan 1, 1970 in all cases but a followup PR can fix that.

* fix encoding BMPString in x509 name entries (#4321)Paul Kehrer2018-07-091-0/+18
| | | | | | | | | | 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.
* Make RelativeDistinguishedName preserve attribtue order (#4306)Marti Raudsepp2018-07-091-6/+9
| | | | Duplicate attributes now raise an error instead of silently discarding duplicates.
* Future proofing use of the six python version constants (#4238)Eric Brown2018-05-142-25/+25
| | | | | | | | | | | | | | | * 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

* Revert "don't allow GeneralNames to be an empty list (#4128)" (#4161)Alex Gaynor2018-03-201-4/+0
| | | | | This breaks the urllib3 tests, as well as several in-the-wild certs This reverts commit 388d1bd3e9cd953fcc948edbc152d5d140c87eb8.

* Fix ASN1 string type encoding for several Name OIDs (#4035)Paul Kehrer2017-11-301-16/+135
| | | | | | | | | | | | | | | | | | | * 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
* Use a different warning class so users get warnings (#4014)Alex Gaynor2017-11-111-2/+2

* backwards incompatible change to UniformResourceIdentifier (#3954)Paul Kehrer2017-10-102-167/+166
| | | | | | | | | | | | | | | * 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 Kehrer2017-10-102-38/+47

* Backwards incompatible change to DNSName (#3951)Paul Kehrer2017-10-103-142/+162
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * 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 Kehrer2017-09-251-0/+58
| | | | | | | | | | | | | | | * 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
