Implements a subset of PKCS#7/Cryptographic Message Syntax (rfc2315, rfc5652) with stream signing and verifying

pkcs7

This is a fork of an excellent pkcs7 package. Copyright (c) 2015 Andrew Smith.

Notable additions to the original library are stream verifying and signing functions. To verify signed message from reader src while writing contents to some writer dest use:

p7 := pkcs7.NewDecoder(r)
if err := p7.VerifyTo(dest); err != nil {
    // handle error
}
// use p7 fields and methods

To sign file src with known size to writer dest:

p7 := pkcs7.NewEncoder(dest)
if err := p7.AddSigner(cert.Certificate, cert.PrivateKey, SignerInfoConfig{}); err != nil {
    // handle add signer error
}
if err = p7.SignFrom(r, size); err != nil {
    // handle write error
}
