Update Information:
# New upstream release 2.3 Fixes possible tag truncation security bug in AEAD
API, see RHBZ#1602752 ## 2.3 - 2018-07-18 * SECURITY ISSUE:
finalize_with_tag() allowed tag truncation by default which can allow tag
forgery in some cases. The method now enforces the min_tag_length provided to
the GCM constructor. * Added support for Python 3.7. * Added extract_timestamp()
to get the authenticated timestamp of a Fernet token. * Support for Python 2.7.x
without hmac.compare_digest has been deprecated. We will require Python 2.7.7 or
higher (or 2.7.6 on Ubuntu) in the next cryptography release. * Fixed multiple
issues preventing cryptography from compiling against LibreSSL 2.7.x. * Added
get_revoked_certificate_by_serial_number for quick serial number searches in
CRLs. * The RelativeDistinguishedName class now preserves the order of
attributes. Duplicate attributes now raise an error instead of silently
discarding duplicates. * aes_key_unwrap() and aes_key_unwrap_with_padding() now
raise InvalidUnwrap if the wrapped key is an invalid length, instead of
ValueError.
