gmime.decrypt_result.DecryptResult decrypt(gmime.types.DecryptFlags flags, string sessionKey, gmime.stream.Stream istream, gmime.stream.Stream ostream)Decrypts the ciphertext input stream and writes the resulting cleartext to the output stream.
When non-null, session_key should be a null-terminated string, such as the one returned by [gmime.decrypt_result.DecryptResult.getSessionKey] from a previous decryption. If the session_key is not valid, decryption will fail.
If the encrypted input stream was also signed, the returned #GMimeDecryptResult will have a non-null list of signatures, each with a #GMimeSignatureStatus (among other details about each signature).
On success, the returned #GMimeDecryptResult will contain a list of certificates, one for each recipient, that the original encrypted stream was encrypted to.
that recursively decrypting it will result in an endless loop, causing a denial of service attack on your application.
