shamirfpe

This is a project to see if I can effectively combine Hashicorp Vault's Shamir secret sharing algorithm with Capital One's format preserving encryption library.

sf := sharmirfpe{}
sf.AddKeyPart([]byte("part1"))
sf.AddKeyPart([]byte("part2"))
sf.AddKeyPart([]byte("part3"))
// clearing key parts should be done by constructing a new shamirfpe object
sf.NewCipher(radix, maxTLen, tweak)
