[gnutls-help] Is AES GCM only in TLS1.2 ?

[jonetsu]

Hello,


The output of the cipher listing, in FIPS mode, filtered for TLS1.2, gives:


% gnutls-cli -l --priority NORMAL | grep 1.2


 TLS_ECDHE_ECDSA_AES_128_GCM_SHA256
 TLS_ECDHE_ECDSA_AES_256_GCM_SHA384
 TLS_ECDHE_ECDSA_CAMELLIA_128_GCM_SHA256
 TLS_ECDHE_ECDSA_CAMELLIA_256_GCM_SHA384
 [...]


Only GCM variation of AES.  Why is GCM the only available AES variation in TLS1.2 ?


Thanks.


Regards.
