SECURITY ISSUE: Fixed a bug where certain sequences of update() calls
when symmetrically encrypting very large payloads (>2GB) could result in
an integer overflow, leading to buffer overflows. CVE-2020-36242
Note: This also updates {,vectors-}3.3.nix (for Python 2 / nixops)
because of the security issue.

|
|
Cryptography includes both high level recipes and low level interfaces to
|
|
common cryptographic algorithms such as symmetric ciphers, message
|
|
digests, and key derivation functions.
|
|
Our goal is for it to be your "cryptographic standard library". It
|
|
supports Python 2.7, Python 3.5+, and PyPy 5.4+.
