AES-GCM authenticated encryption. AES with Galois/Counter Mode (AES-GCM) provides both authenticated encryption (confidentiality and authentication) and the ability to check the integrity and authentication of additional authenticated data (AAD) that is sent in the clear. AES-GCM is specified in NIST Special Publication 800-38D . There are four

The AWS Encryption SDK algorithm suite uses the Advanced Encryption Standard (AES) algorithm in Galois/Counter Mode (GCM), known as AES-GCM, to encrypt raw data. The SDK supports 256-bit, 192-bit, and 128-bit encryption keys.
GCM provides assurance of the confidentiality of data using a variation of the Counter mode of operation for encryption. GCM provides assurance of the authenticity of the confidential data (up to about 64 gigabytes per invocation) using a universal hash function that is defined over a binary Galois field.

Java AES 256 GCM Encryption and Decryption Example | JCE AES-GCM is a block cipher mode of operation that provides high speed of authenticated encryption and data integrity. In GCM mode, the block encryption is transformed into stream encryption, and therefore no padding is needed.The Additional Authenticated Data (AAD) will not be encrypted but used in the computation of Authentication Tag.The authenticated encryption operation takes Initialization AesGcm Class (System.Security.Cryptography) | Microsoft Docs Represents an Advanced Encryption Standard (AES) key to be used with the Galois/Counter Mode (GCM) mode of operation. In this article public ref class AesGcm sealed : IDisposable GCM and GMAC authenticated encryption algorithms GCM provides assurance of the confidentiality of data using a variation of the Counter mode of operation for encryption. GCM provides assurance of the authenticity of the confidential data (up to about 64 gigabytes per invocation) using a universal hash function that is defined over a binary Galois field.
