z85 is a dead-simple tool to encode into and decode from the Z85 format often seen in ZeroMQ. It features a single optional command for the mode (encoding is assumed if not present), reading data from stdin and writing to stdout.
If you have Go installed, simply run:
go get github.com/CarsonHoffman/z85If you'd rather install a binary, head over to the releases page and drop the appropriate binary for your platform somewhere included in your PATH.
Using z85 couldn't be simpler—to encode data, all that needs to be done is to run the z85 command, supplying data via stdin. Here's an example of encoding some public key data into Z85:
$ z85 < pubkey
@HtIbum3ML:*am5qH9Dvp3dPsROdqfC5-4pkIDRUTake care that the length of your data is a multiple of 4 as required by the Z85 format; tools like echo may unexpextedly append a newline to your input (for echo, supply the -n flag to disable this behavior). Here's an example of using echo to pipe in data:
$ echo -n "testdata" | z85
By/JnwmoN*Decoding data is almost as simple as encoding; we simply need to supply an extra argument to specify that we're decoding: z85 decode (or z85 d for short). Here are a few examples of the inverses of above:
$ echo -n "@HtIbum3ML:*am5qH9Dvp3dPsROdqfC5-4pkIDRU" | z85 d > pubkey_decoded
$ diff pubkey pubkey_decoded
$ echo -n "By/JnwmoN*" | z85 d
testdataAnd that's all you need to know! Get out there and make some awesome stuff in ZeroMQ; if you ever need to get the Z85 encoding of a public key, z85 will be waiting.
Thanks to tilinna for their package which provides the actual Z85 functionality for this tool.
