SecuMail is a partial implementation of the OpenPGP standard (RFC2440,RFC4880) that leverages your current cryptography infrastructure and allows your iOS devices to interoperate with it. SecuMail currently implements a subset of the standard that allows you to encrypt, decrypt, sign and verify OpenPGP messages.
