2019-01-22changelog and version bump for 2.5 (#4729)Paul Kehrer
2019-01-22allow asn1 times of 1950-01-01 and later. (#4728)Paul Kehrer
* allow asn1 times of 1950-01-01 and later. * add a test * pretty up the test
2019-01-21allow 32-bit platforms to encode certs with dates > unix epoch (#4727)Paul Kehrer
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.
2019-01-21bind EVP_R_MEMORY_LIMIT_EXCEEDED and update a test (#4726)Paul Kehrer
* bind EVP_R_MEMORY_LIMIT_EXCEEDED and update a test This will allow OpenSSL 1.1.1 on 32-bit (including our Windows 32-bit builders) to fail as expected. Technically this isn't a malloc error, but rather failing because the allocation requested is larger than 32-bits, but raising a MemoryError still seems appropriate * what you want an endif too?

2018-12-08Updated BLAKE2s and BLAKE2b error messages from unsupportedalgorithm … (#4519)Colin Metcalf
* Updated BLAKE2s and BLAKE2b error messages from unsupportedalgorithm exception to an explicit error. The error is now "ValueError: Digest size must be 32" (or 64 for BLAKE2b) This was done to give a more contextual error message and should be in place until OpenSSL supports variable lengths. * Updated if statements in hashes.py so that they no longer wrap to separate line. Updated test_hashes.py to unclude a test for non 32 or 64 digest_sizes that fall between 0-32/64. * Removed the new tests in test_hashes.py as the old ones were satisfactory. This also solved misaligned tabs and spaces. * Removed dead code in hashes.py that could no longer be reached after error message updates. * pep8 fix * remove superfluous parens
