NAME
Bitcoin::Crypto::Base58 - Bitcoin's Base58 helpers
SYNOPSIS
# none exported by default
use Bitcoin::Crypto::Base58 qw(
encode_base58
decode_base58
encode_base58check
decode_base58check
);
my $b58str = encode_base58check(pack "A*", "hello");
my $bytestr = decode_base58check($b58str);DESCRIPTION
Implementation of Base58Check algorithm and alias to CryptX encode_b58b / decode_b58b
FUNCTIONS
This module is based on Exporter. None of the functions are exported by default. :all tag exists that exports all the functions at once.
encode_base58
decode_base58
Basic base58 encoding / decoding.
Encoding takes one argument which is byte string.
Decoding takes base58-encoded string
These two functions are just aliases to "encode_b58b" in Crypt::Misc and "decode_b58b" in Crypt::Misc with some error checking.
encode_base58check
decode_base58check
Base58 with checksum validation. These functions are used with Bitcoin legacy / compatibility addresses.
Arguments are the same as base functions mentioned above.
Additional errors (other than illegal characters) are thrown.
EXCEPTIONS
This module throws an instance of Bitcoin::Crypto::Exception if it encounters an error. It can produce the following error types from the Bitcoin::Crypto::Exception namespace:
Base58InputFormat - input was not suitable for base58 operations due to invalid format
Base58InputChecksum - checksum validation has failed
