Sorry for starting a new message, somehow I only get the digest and
not the reply to my posted message.
I'm actually looking for pseudo code for a minimal implementation of pgp-mime.
Not using gpgme.
No C code.
So.. I have a feeling this is an impossible request.
And that perhaps a full implementation is the *only* implementation.
I believe that bouncy castle has pgp support. So I will probably be
able to use that.
I was hoping to find something like:
A minimal pgp-mime.
1. Canonicalize message.
2. Write a "encrypted/pgp-mime" mime-part.
3. Within mime-part write b64(encrypt(canon-message)).
Where encrypt is "rsa(aes-256-key) + aes-256(message) +
sha-256(previously written bytes)"
4. Add mime-part attachment in format:
Some indicator of encryption version used. And my public key.
I'm looking for a simplest of simple implementations which could then
be expanded on.
Perhaps this is impossible.
