SYNOPSIS

10           use Net::SSH::Perl::Cipher;
11           my $eight_byte_iv = pack('N',0) . pack('N',1);
12           my $eight_byte_counter = chr(1) . 7 x "\0"; # little endian
13
14           my $cipher = Net::SSH::Perl::Cipher->new('ChachaPoly', $key);
15
16           # generate poly key
17           $cipher->ivsetup($eight_byte_iv,undef);
18           my $poly_key = "\0" x POLY1305_KEYLEN; # 32 byte key
19           $poly_key = $ciph->encrypt($poly_key);
20
21           $cipher->ivsetup($eight_byte_iv,$eight_byte_counter);
22           my $enc = $cipher->encrypt($plaintext);
23           my $tag = $cipher->poly1305($enc,$poly_key);
