NAME

TweetNacl - pulic key crypto lib

SYNOPSIS

# ----------------------------------------------------------------------
# public key encryption
# ----------------------------------------------------------------------

use Crypt::TweetNacl::PublicKey;

# create keys
my $alice = KeyPair.new;
my $bob = KeyPair.new;

# create Buf to encrypt
my $msg = 'Hello World'.encode('UTF-8');

# encrypt
my $cb = CryptoBox.new(pk => $alice.public , sk => $bob.secret);
my $data = $cb.encrypt($msg);

# decrypt
my $cbo = CryptoBoxOpen.new(pk => $bob.public , sk => $alice.secret);
my $rmsg = $cbo.decrypt($data);
say $rmsg.decode('UTF-8')



# ----------------------------------------------------------------------
# public key signatures
# ----------------------------------------------------------------------

use Crypt::TweetNacl::Sign;

# create key
my $keypair = KeyPair.new;
my $msg = 'Hello World'.encode('UTF-8');

# sign
my $cs = CryptoSign.new(buf => $msg, sk => $keypair.secret);
say $cs.signature


# verify, throws if message was corrupted
my $cso = CryptoSignOpen.new(buf => $cs.signature, pk => $keypair.public);
say $cso.message.decode('UTF-8') # 'Hello World'

# ----------------------------------------------------------------------
# secret key encryption
# ----------------------------------------------------------------------

use Crypt::TweetNacl::SecretKey;

# create key
my $alice = Key.new;

# create Buf to encrypt
my $msg = 'Hello World'.encode('UTF-8');

# encrypt
my $csb = CryptoSecretBox.new(sk => $alice.secret);
my $data = $csb.encrypt($msg);

# decrypt
my $csbo = CryptoSecretBoxOpen.new(sk => $alice.secret);
my $rmsg = $csbo.decrypt($data);
say $rmsg.decode('UTF-8') # 'Hello World'

INSTALL

# on debian like systems:

apt install rakudo moarvm-dev
git clone https://github.com/soundart/perl6-tweetnacl
cd perl6-tweetnacl
zef install .

DESCRIPTION

For details see

This is my first perl6 attempt. Feedback very much appreciated.

open questions:

class Ciphertext: attributes $!data and $!nonce have to be transported(e.g. send via network) from encryption to decryption host. Should there be a serialize() method?
