# 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](http://rfc.zeromq.org/spec:32)) for encoding binary data as plain text. Modelled on the [PyZMQ](http://zeromq.github.io/pyzmq/) implementation. This module uses [Exporter::Tiny](https://metacpan.org/pod/Exporter::Tiny) to export two functions by default: ["encode\_z85"](#encode_z85) and ["decode\_z85"](#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"](#encode_z85)) is not handled automatically; the **pad** option can be specified to remove trailing zero bytes: my $bin = decode_z85($encoded, pad => 1); # SEE ALSO [Convert::Ascii85](https://metacpan.org/pod/Convert::Ascii85) [POEx::ZMQ](https://metacpan.org/pod/POEx::ZMQ) [ZMQ::FFI](https://metacpan.org/pod/ZMQ::FFI) # AUTHOR Jon Portnoy <avenj@cobaltirc.org>
