That is the question. I want to save some keys in cold storage in a durable medium, but I don't have the means to use all the base58 charset. HEX would be a good format.
Does anybody know a solution? I guess I could roll my own quick script or tool, but this could go horribly bad if I make a mistake. On a related question, any trustable test vectors on there for hex<->base58 converters that include bip38 keys?
I actually don't think this Library has bip38 support but its worth checking out, I have used it quite a bit in the past.
