Usage

From source file:fi.csc.emrex.smp.openpgp.PGPEncryptionUtil.java

public PGPEncryptionUtil(PGPPublicKey key, String payloadFilename, OutputStream out)
        throws PGPException, NoSuchProviderException, IOException {
    Security.addProvider(new org.bouncycastle.jce.provider.BouncyCastleProvider());
    // write data out using "ascii-armor" encoding.  This is the
    // normal PGP text output.
    this.armoredOutputStream = new ArmoredOutputStream(out);

    // create an encrypted payload and set the public key on the data generator
    PGPEncryptedDataGenerator encryptGen = new PGPEncryptedDataGenerator(PAYLOAD_ENCRYPTION_ALG,
            new SecureRandom(), BC_PROVIDER_NAME);
    encryptGen.addMethod(key);//from w  ww  . ja v  a  2  s  . c om

    // open an output stream connected to the encrypted data generator
    // and have the generator write its data out to the ascii-encoding stream
    this.encryptedOut = encryptGen.open(armoredOutputStream, new byte[BUFFER_SIZE]);

    // compress data.  we are building layers of output streams.  we want to compress here
    // because this is "before" encryption, and you get far better compression on
    // unencrypted data.
    PGPCompressedDataGenerator compressor = new PGPCompressedDataGenerator(PGPCompressedData.ZIP);
    this.compressedOut = compressor.open(encryptedOut);

    // now we have a stream connected to a data compressor, which is connected to
    // a data encryptor, which is connected to an ascii-encoder.
    // into that we want to write a PGP "literal" object, which is just a named
    // piece of data (as opposed to a specially-formatted key, signature, etc)
    PGPLiteralDataGenerator literalGen = new PGPLiteralDataGenerator();
    this.literalOut = literalGen.open(compressedOut, PGPLiteralDataGenerator.UTF8, payloadFilename, new Date(),
            new byte[BUFFER_SIZE]);
}
