libgcrypt now uses ciphertext blinding for Elgamal decryption
(CVE-2014-3591)
FIPS 140-2 related changes:
* The library performs its self-tests when the module is complete (the
 -hmac file is also installed).
* Added a NIST 800-90a compliant DRBG.
* Change DSA key generation to be FIPS 186-4 compliant.
* Change RSA key generation to be FIPS 186-4 compliant.
* Enable HW support in fips mode (bnc#896435)
* Make DSA selftest use 2048 bit keys (bnc#898003)
* Added ECDSA selftests and add support for it to the CAVS testing
 framework (bnc#896202)
* Various CAVS testing improvements.");
