When connecting from NSS to NSS with all-defaults, mlkem768x25519 group is now selected in RHEL-10.1
and that trips FIPS indicator. I see:
tstclnt: SSL version 3.4 using 128-bit AES-GCM with 128-bit AEAD MAC tstclnt: Server Auth: 2048-bit TLS 1.3, Key Exchange: 255-bit TLS 1.3 Key Exchange Group:mlkem768x25519
as opposed to 10.0's
tstclnt: SSL version 3.4 using 128-bit AES-GCM with 128-bit AEAD MAC FIPS tstclnt: Server Auth: 2048-bit TLS 1.3, Key Exchange: 256-bit TLS 1.3 Key Exchange Group:P256
cmd/tstclnt/tstclnt.c:172 conditions printing that "FIPS" bit on channel.isFIPS value.
I expect that to not be the case and mlkem768x25519 usage to be approved in FIPS mode.
