    * Improve padding calculations in CBC decryption, NIST key unwrapping and
      RSA OAEP decryption. With the previous implementation, some compilers
-     (notably recent versions of Clang) could produce non-constant time code,
-     which could allow a padding oracle attack if the attacker has access to
-     precise timing measurements.
