Modifier and Type	Method and Description
java.lang.String	digest(byte[] content) Produces the digest of a byte array
java.lang.String	digest(java.nio.channels.ByteChannel channel) Digests a ByteChannel; the performance of this method may possibly be higher (but it may also be slightly slower) than that of the InputStream method
java.lang.String	digest(java.io.File file) Produces the digest of a File
java.lang.String	digest(java.io.InputStream is) Produces the digest of an InputStream
