Aes_256_gcm frente a aes_128_gcm
If you really want to mess with this, you'd have to disable the mandatory cipher suite in the OpenSSL CONF library configuration files openssl.cnf as explained in e.g.

AES (Advanced Encryption Standard) is a symmetric block cipher standardized by NIST . It has a fixed data block size of 16 bytes. Its keys can be 128, 192, or 256 bits long.

New CPU's from INTEL also includes instructions for GCM mode. 04/05/2019 We’re happy to announce that we have added the aes128-gcm and aes256-gcm Ciphers to the latest build of Xshell. So if you’re server requires either of these encryption types, … 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").

This keystream is formed one block at a time by inputting the concatenation of a 12-octet IV (see Sections 8.1 and 9.1) with a 4-octet block to AES. 20/05/2015 Avoid support scams.

We also add support for the AES-192-GCM algorithm (RFC 5116 only has AES-128-GCM and AES-256-GCM). There is no option to use different lengths for the IV or tag.

"aes 256 -gcm" i am looking for opinions based on security and reliability. Thanks !! Sourav Saha 0 Likes Reply. MP18. Cyber Elite 10-25-2020 10:07 although AES-256-GCM is available, it is costly from the computational point of view at this time and should be used with other practices and methods to ensure greater security and privacy. AES-256 is only 40% slower compared to AES-128.
