Daniel P. Berrange	eb2a770b17	crypto: don't let builtin aes crash if no IV is provided ... If no IV is provided, then use a default IV of all-zeros instead of crashing. This gives parity with gcrypt and nettle backends. Signed-off-by: Daniel P. Berrange <berrange@redhat.com>	2015-10-22 19:03:08 +01:00
Daniel P. Berrange	6775e2c429	crypto: fix built-in AES decrypt function ... The qcrypto_cipher_decrypt_aes method was using the wrong key material, and passing the wrong mode. This caused it to incorrectly decrypt ciphertext. Signed-off-by: Daniel P.

Paolo Bonzini	4f4f6976d8	crypto: fix builtin qcrypto_cipher_free ... This was dereferencing a pointer before checking if it was NULL.

Daniel P. Berrange	ca38a4cc9e	crypto: introduce generic cipher API & built-in implementation ... Introduce a generic cipher API and an implementation of it that supports only the built-in AES and DES-RFB algorithms. The test suite checks the supported algorithms + modes to validate that every backend implementation is actually correctly complying with the specs. Signed-off-by: Daniel P.
