Hi!
2 questions about GCM and the following OpenSSL-Sample please.
https://wiki.openssl.org/index.php/EVP_Authenticated_Encryption_and_Decryption#Authenticated_Decryption_using_GCM_mode
and the function
int decrypt(unsigned char *ciphertext, int ciphertext_len, unsigned char
*aad, int aad_len, unsigned char *tag, unsigned char *key, unsigned char
*iv, unsigned char *plaintext)
* Is ciphertext the pure ciperhtext OR
is it with IV and TAG still in the string??
* If the 2nd: The IV is expected to be in front of the ciphertext and
the TAG is expected to be past of the ciphertext - correct?
| IV | ciphertext | TAG |
thanks!
Christoph
