Throws:

PGPException

isPublicKeyEncrypted

protected boolean isPublicKeyEncrypted()

Whether this data was decrypted from a public-key (or otherwise already-recovered session key) rather than from a password (PBE). The CFB "quick check" is suppressed on the public-key / session-key path (it would only re-create the Mister-Zuccherato oracle and there is no multi-SKESK passphrase retry to drive); PBE keeps it. Overridden by PGPSessionKeyEncryptedData.
