EncryptionInfo Event

Reports early information on encryption parameters.

Syntax

type TEncryptionInfoEvent = procedure (
  Sender: TObject;
  const KeyIDs: String;
  IntegrityProtected: Boolean;
  PassphraseUsed: Boolean
) of Object;

property OnEncryptionInfo: TEncryptionInfoEvent read FOnEncryptionInfo write FOnEncryptionInfo;

Remarks

The component fires this event to report early encryption information. Use this event to find out what encryption type is used, and to provide appropriate decryption material (the secret keys or the password) via DecryptingKeys or Passphrase properties.

KeyIDs contains the IDs of the keys that can be used to decrypt the data. PassphraseUsed shows if the message can also be decrypted with a passphrase. Both can be set at the same time, indicating that each of the decryption routes can be taken.

IntegrityProtected parameter specifies whether the message includes a modification detection record.
