The purpose of this designation is to document how the crypto is configured, so it has to include all the detail, including WITH_AES_128_GCM_SHA256.

Why AES-GCM Sucks – Dhole Moments

TLS_RSA_WITH_AES_256_CBC_SHA comes to be weak cipher? In last year general plan Announcing SSL Labs Grading Changes for 2017 there is a statement if server uses only Forward Secrecy ciphers the grade will go down to B. This hasn't happened yet, but currently implemented ssllabs test there is a warning that servers only supporting non-forward secrecy ciphers grade will be reduced to B from March 2018.

TLS_ECDHE_ECDSA_WITH_AES_128_GCM_SHA256 is a TLSv1.2 cipher suite. It can not be used with SSLv3 or TLSv1. Also, it might not be even available for the unknown Advanced Encryption Standard with 128bit key in Galois/Counter mode (AES 128 GCM) Hash: Secure Hash Algorithm 256 (SHA256) Included in RFC: RFC 5289 Feb 10, 2020 · GCM uses a key size of 128, 192 or 256 bits according to AES, and the block size of 128 bits. The initialization vector (iv) is restricted to lengths less than or equal to 2 64 -1 in multiples of 8. You cannot use a symmetric cipher with a smaller block size because GCM was designed for 128-bit ciphers. Hi all I am a pro customer and having weak cipher suite problem.
