SECURITY ISSUE: Attempted to make RSA PKCS#1v1.5 decryption more constant time, to protect against Bleichenbacher vulnerabilities. Due to limitations imposed by our API, we cannot completely mitigate this vulnerability and a future release will contain a new API which is designed to be resilient to these for contexts where it is required. Credit to Hubert Kario for reporting the issue. CVE-2020-25659
Support for OpenSSL 1.0.2 has been removed. Users on older version of OpenSSL will need to upgrade.
Added basic support for PKCS7 signing (including SMIME) via ~cryptography.hazmat.primitives.serialization.pkcs7.PKCS7SignatureBuilder.
