Thanks for this great service, love the interface!

Unfortunately I found that I cannot reliably encode random 256-bit key from binary to Ascii85 and back. It loses precision in the process; some byes are converted to 0x00.

Also, it would be great to have support for ZeroMQ's Z85 encoding, in a similar way that I can choose subsets of Base64 encodings. As in: Base85 ( Ascii85 or Z85 ).
