java.security.NoSuchAlgorithmException

encrypt

public static byte[] encrypt(byte[] clearData,
                             java.io.InputStream keyRing,
                             java.lang.String fileName,

                             java.security.NoSuchAlgorithmException

Simple PGP encryptor between byte[].

Parameters:

clearData - The test to be encrypted

keyRing - public key ring input stream

fileName - File name. This is used in the Literal Data Packet (tag 11) which is really only important if the data is to be related to a file to be recovered later. Because this routine does not know the source of the information, the caller can set something here for file name use that will be carried. If this routine is being used to encrypt SOAP MIME bodies, for example, use the file name from the MIME type, if applicable. Or anything else appropriate.

withIntegrityCheck - true if an integrity packet is to be included

armor - true for ascii armor

ids - destination ids

Returns:

encrypted data.

Throws:

java.io.IOException

org.bouncycastle.openpgp.PGPException

java.security.NoSuchProviderException

java.security.NoSuchAlgorithmException

                             boolean withIntegrityCheck,
                             boolean armor,
