An update that has one recommended fix can now be installed.
Description:
This update provides python-cryptography 1.1.2, which brings many fixes
and enhancements:
- Fixed a runtime error 'undefined symbol EC_GFp_nistp224_method' that
occurred with some OpenSSL installations.
- Fixed several small bugs related to compiling the OpenSSL bindings with
unusual OpenSSL configurations.
- Added support for Elliptic Curve Diffie-Hellman.
- Added support for parsing certificate revocation lists (CRLs).
- Add support for AES key wrapping.
- Add support for encoding and decoding elliptic curve points to a byte
string form.
- 'countryName' is now encoded as a 'PrintableString' when creating
subject and issuer distinguished names with the Certificate and CSR
builder classes.
- The OpenSSL backend prior to 1.0.2 made extensive use of assertions to
check response codes where our tests could not trigger a failure.
However, when Python is run with '-O' these asserts are optimized away.
If a user ran Python with this flag and got an invalid response code
this could result in undefined behavior or worse. Accordingly, all
response checks from the OpenSSL backend have been converted from
'assert' to a true function call.
- Set the default string mask to UTF-8 in the OpenSSL backend to resolve
character encoding issues with older versions of OpenSSL.
- Several new OpenSSL bindings have been added to support a future
pyOpenSSL release.
