                                         OpenPgpSelf self,
                                         java.util.Collection<OpenPgpContact> recipients)
                                  throws java.io.IOException,
                                         org.bouncycastle.openpgp.PGPException

Sign a SigncryptElement using our signing key and encrypt it for all recipients and ourselves.

Parameters:

element - SigncryptElement which contains a payload which will be transmitted.

self - our own OpenPGP identity.

recipients - recipients identities.

Returns:

signed and encrypted SigncryptElement as a OpenPgpElement, along with OpenPgpMetadata about the encryption/signatures.

Throws:

java.io.IOException - IO is dangerous

org.bouncycastle.openpgp.PGPException - PGP is brittle

                               OpenPgpSelf self)
                        throws java.io.IOException,
                               org.bouncycastle.openpgp.PGPException

Sign a SignElement using our signing key.

Parameters:

element - SignElement which contains a payload.

self - our OpenPGP identity.

Returns:

signed SignElement as OpenPgpElement, along with OpenPgpMetadata about the signatures.

Throws:

java.io.IOException - IO is dangerous

org.bouncycastle.openpgp.PGPException - PGP is brittle

encrypt

OpenPgpElementAndMetadata encrypt(CryptElement element,
                                  OpenPgpSelf self,
                                  java.util.Collection<OpenPgpContact> recipients)
                           throws java.io.IOException,
                                  org.bouncycastle.openpgp.PGPException

Parameters:

element - CryptElement which contains a payload which will be transmitted.

self - our own OpenPGP identity.

recipients - recipient identities.

Returns:

encrypted CryptElement as an OpenPgpElement, along with OpenPgpMetadata about the encryption.

Throws:

java.io.IOException - IO is dangerous

org.bouncycastle.openpgp.PGPException - PGP is brittle

OpenPgpMessage decryptAndOrVerify(XMPPConnection connection,
                                  OpenPgpElement element,
                                  OpenPgpSelf self,
                                  OpenPgpContact sender)
                           throws java.io.IOException,
                                  org.bouncycastle.openpgp.PGPException

Decrypt and/or verify signatures on an incoming OpenPgpElement. If the message is encrypted, this method decrypts it. If it is (also) signed, the signature will be checked. The resulting OpenPgpMessage contains the original OpenPgpContentElement, as well as information about the encryption/signing.

Parameters:

element - signed and or encrypted OpenPgpElement.

self - our OpenPGP identity.

sender - OpenPGP identity of the sender.

connection - XMPP connection used to fetch any missing keys.

Returns:

decrypted message as OpenPgpMessage.

Throws:

java.io.IOException - IO is dangerous

org.bouncycastle.openpgp.PGPException - PGP is brittle
