NAME

Convert::Z85 - Encode and decode Z85 strings

SYNOPSIS

  use Convert::Z85;

  my $encoded = encode_z85($binarydata);
  my $decoded = decode_z85($encoded);

DESCRIPTION

An implementation of the Z85 encoding scheme (as described in ZeroMQ spec 32) for encoding binary data as plain text.

Modelled on the PyZMQ implementation.

This module uses Exporter::Tiny to export two functions by default: "encode_z85" and "decode_z85".

encode_z85

  my $z85 = encode_z85($data);

Takes binary data in 4-byte chunks and returns a Z85-encoded text string.

Per the spec, padding is not performed automatically; the pad option can be specified to pad data with trailing zero bytes:

  my $z85 = encode_z85($data, pad => 1);

decode_z85

  my $bin = decode_z85($encoded);

Takes a Z85 text string and returns the original binary data.

Dies (with a stack trace) if invalid data is encountered.

Padding (see "encode_z85") is not handled automatically; the pad option can be specified to remove trailing zero bytes:

  my $bin = decode_z85($encoded, pad => 1);
