The unique identifier of the event is provided in the EventID parameter. EventParam contains any parameters accompanying the occurrence. Depending on the type of the class, the exact action it is performing, or the document being processed, one or both may be omitted.
PGPKey Type
This container represents a PGP key.
Remarks
OpenPGP standard supports several types of keys. In our days, a typical OpenPGP keypair actually consists of two cryptographic keys: a primary key and a subkey. The primary key is normally used for signing, while the subkey is used for encryption.
While it is typical for PGP environments to use a primary key/subkey bundle, this is not a must. Sometimes you may come across standalone keys (mainly when dealing with older implementations), as well as whole key trees, each of those carrying a bunch of differently-purposed subkeys bound to the same primary key.
Algorithm-wise, OpenPGP keys also differ. Generally speaking, OpenPGP supports the following public key algorithms: RSA, Elgamal (often incorrectly referred to as DH), DSA, ECDH and ECDSA. When it comes to primary key/subkey bundles, DSA/Elgamal, RSA/RSA and ECDSA/ECDH pairs are typically used. Although there's no restriction on algorithm bundles, and, e.g. a ECDSA/Elgamal key bundle is perfectly possible, such combination is rarely used in practice.
A typical OpenPGP key is associated with some kind of user ID (Username). It is normally represented with a user's e-mail address, while in theory can be any piece of text. The secret part of the OpenPGP keypair is protected with a password (Passphrase).
