init_symmetric_state

$hs = init_symmetric_state($cnf, $hs);

mix_key

$ss = mix_key( $cnf, $ss, $dh );

mix_hash

$ss = mix_hash( $cnf, $ss, $data );

init_key

$ss = init_key($ss, $k);

has_key

my $is_has_key = has_key($ss);

set_nonce

$ss = set_nonce($ss, $n);

mix_keyandhash

$ss = mix_keyandhash( $cnf, $ss, $data );

noise_split

my ($c1, $c2) = noise_split( $cnf,     $ss );

init_ciphersuite_name

my $ciphersuite_name = init_ciphersuite_name($cnf);

init_handshake_pattern

my $pattern = init_handshake_pattern($hs);

init_protocol_name

my $protocol_name = init_protocol_name( $cnf, $hs );

new_handshake_state

$hs = new_handshake_state( $cnf, $hs );

rekey

my $k = rekey( $cnf, $hs );

encrypt_with_ad

my $cipher_info = encrypt_with_ad( $cnf, $ss, $ad, $plaintext );

decrypt_with_ad

my $plaintext = decrypt_with_ad($cnf, $ss, $ad, $cipher_info);

encrypt_and_hash

OPTIONAL SESSION FUNCTION

use c1/c2 with set nonce directly

or

derive sub { key, iv } from c1/c2, and calc iv' = iv xor current_time, to make sure iv' is not resuse

derive_session_key_iv

my ($sk, $siv) = derive_session_key_iv($cnf, $k, $salt);

session_encrypt

my $cipher_info = session_encrypt( $cnf, $key, $iv, $aad, $plaintext );

session_decrypt

my $plaintext = session_decrypt( $cnf, $key, $iv, $aad, $cipher_info );
