OpenPGP Class

Properties   Methods   Events   Configuration Settings   Errors  

The OpenPGP component is used to encrypt/decrypt and sign/verify PGP messages.

Syntax

ipworksencrypt.openpgp()

Remarks

The OpenPGP class supports encrypting/decrypting and signing/verifying OpenPGP messages in the format specified by RFC 4880.

The Encrypt, Sign, and SignAndEncrypt methods are used to create a message to be sent to your partner. You can additionally create messages bound for multiple recipients with different keys, simultaneously encrypt and compress with the most popular compression algorithms, and control other aspects such as the encrypting algorithm to use.

When a message is received, the Decrypt, VerifySignature, and DecryptAndVerifySignature methods are used to process the incoming message.

The Key* properties specify the key (with private key) used to sign and decrypt.

The SignerKey* properties specify the key used to verify a signature.

The RecipientKey* properties specify the key used to encrypt.

Input and Output Properties

The class will determine the source and destination of the input and output based on which properties are set.

The order in which the input properties are checked is as follows:

When a valid source is found the search stops. The order in which the output properties are checked is as follows:
