The use of binary for CURVE keys is painful; you cannot easily copy these in e.g. email, or use them directly in source code. There are various encoding possibilities. Base16 and Base64 are not optimal. Ascii85 is not safe for source (it generates quotes and escapes). So, I've designed a new Base85 encoding, Z85, which is safe to use in code and elsewhere, and I've modified libzmq to use this where it also uses binary keys (in get/setsockopt). Very simply, if you use a 32-byte value, it's Base256 (binary), and if you use a 40-byte value, it's Base85 (Z85). I've put the Z85 codec into z85_codec.hpp, it's not elegant C++ but it is minimal and it works. Feel free to rewrap as a real class if this annoys you.
