libcrypto fully implemented Implemented working versions of the following functions for libcrypto: sss_base64_encode sss_base64_decode sss_hmac_sha1 sss_password_encrypt sss_password_decrypt test_encrypt_decrypt now expects EOK from libcrypto. test_hmac_sha1 now expects EOK from libcrypto. Added test_base64_encode to test base64 encoding implementation. Added test_base64_decode to test base64 decoding implementation. Signed-off-by: George McCollister <George.McCollister@gmail.com>
