The RFC shows an [overvi Two generations of encryption mechanisms are currently relevant in OpenPGP, and will co-exist for the foreseeable future. The main difference between these lies in the symmetric part of the encryption mechanism, represented by versions 1 and 2 of the *Symmetrically Encrypted and Integrity Protected Data* packets (abbreviated as "SEIPD"). More on these below. -Older, legacy encryption mechanisms exist in OpenPGP. However, those must not be used for encryption anymore.

That is, the decrypted data consists of a series of OpenPGP packets. In both versions of SEIPD, the decryptor has obtained a *session key* in a previous step - before processing the SEIPD packet. Using this session key, the decryptor can decrypt the SEIPD packet and process the contained plaintext data.
