I am familiar with mcrypt functions, but I've never come across OpenSSL in PHP. Any clues how to use it? – c00000fd Feb 3 '15 at 9:27 SQL Server AEAD AES 128-bit GCM - Example Code (SQL Server) AEAD AES 128-bit GCM. Demonstrates AES encryption using the Galois/Counter Mode (GCM). GCM is an authenticated encryption mode with "additional data" (often referred to as AEAD). GCM is a cipher mode that can be applied to any symmetric encryption algorithm with a 16-byte block size, such as AES and Twofish. OpenSSL C example of AES-GCM using EVP interfaces - Stack For AES-GCM encryption/decryption, I tried this, but it has a problem. ctx = EVP_CIPHER_CTX_new(); //Get the cipher. cipher = EVP_aes_128_gcm (); #define GCM_IV "000000000000" #define GCM_ADD "0000" #define TAG_SIZE 16 #define ENC_SIZE 64 //Encrypt the data first.
