Question:

Decrypting MIME email in RFC-8222 wrapped format?

Jul 07 '14 at 10:44

I want to know if there an component/function that can decrypt and extract RFC-8222 wrapped messages?

(In wrapped format, the following header fields will be moved from the outer RFC 822 header into the encrypted part of the message: To, From, Subject, Date).

I'm using CkMime_ExtractPartsToFiles to extract the decrypted file. It works with unwrapped message though.

Use the CkMime_UnwrapSecurity function to do it.

Heres what im doing.

using CkDecryptFile to decrypt mime.p7m into mime.txt

CkMime_LoadMimeFile(MimeOBJ, mime.txt);

CkMime_UnwrapSecurity(aMimeObj);

CkMime_ExtractPartsToFiles(aMimeObj, unwrap.txt);

This works when mime.p7m is Un-wrapped, and when ExtractPartsToFiles is called I get the desired result.
