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
