AES 128 GCM is again the same cipher, used in Galois Counter Mode. It is important to note that GCM mode also provides authentication of the data (it is a mode for "Authenticated Encryption"). If you want to get a general idea of the different block cipher modes, you can check the entry in Wikipedia. Cipher suite - Wikipedia AES_128_GCM indicates the block cipher being used to encrypt the message stream, together with the block cipher mode of operation. SHA256 indicates the message authentication algorithm which is used to authenticate a message. Full handshake: coordinating cipher suites. aes gcm - Why GCM operation mode with AES-128 is AES can be used with 128,192, and 256-bit key sizes and always with 128-bit block size †.. In NIST 800-38d, GCM is defined for 128-bit block size, since it is operating on block size and doesn't mandate about the key size.. This Recommendation specifies an algorithm called Galois/Counter Mode (GCM) for authenticated encryption with associated data. What's the difference between AES-CBC and AES-GCM

The page shows the SSL/TLS capabilities of your web browser, determines supported TLS protocols and cipher suites, and marks if any of them are weak or insecure, displays a list of supported TLS extensions and key exchange groups. Using this data, it calculates the TLS-fingerprint in JA3 format. It also tests how your web browser handles requests for insecure mixed content.
