Is there a sign and a verify function ?

[ellis2323]

i found the encrypt and decrypt functions but no sign and verify functions ? i could be an useful improvement. Should we use ethereumjs-util to do theses operations.
Best regards

not in keythereum but you can find it in https://github.com/ethereumjs/ethereumjs-util/blob/master/index.js#L327
