Class PGPUtil

public class PGPUtil extends Object implements HashAlgorithmTags

Basic utility class

Method Summary
static InputStream	getDecoderStream(InputStream in) Return either an ArmoredInputStream or a BCPGInputStream based on whether the initial characters of the stream are binary PGP encodings or not.
static String	getDefaultProvider() Return the provider that will be used by factory classes in situations where a provider must be determined on the fly.
static SecretKey	makeKeyFromPassPhrase(int algorithm, char[] passPhrase, String provider)
static SecretKey	makeKeyFromPassPhrase(int algorithm, S2K s2k, char[] passPhrase, String provider)
static SecretKey	makeRandomKey(int algorithm, SecureRandom random)
static void	setDefaultProvider(String provider) Set the provider to be used by the package when it is necessary to find one on the fly.
static void	writeFileToLiteralData(OutputStream out, char fileType, File file) write out the passed in file as a literal data packet.
static void	writeFileToLiteralData(OutputStream out, char fileType, File file, byte[] buffer) write out the passed in file as a literal data packet in partial packet format.
