Package org.apache.commons.codec.digest

Class DigestUtils

java.lang.Object

org.apache.commons.codec.digest.DigestUtils

public class DigestUtils
extends Object

Operations to simplify common MessageDigest tasks. This class is immutable and thread-safe. However the MessageDigest instances it creates generally won't be.

The MessageDigestAlgorithms class provides constants for standard digest algorithms that can be used with the getDigest(String) method and other methods that require the Digest algorithm name.

Note: the class has shorthand methods for all the algorithms present as standard in Java 6. This approach requires lots of methods for each algorithm, and quickly becomes unwieldy. The following code works with all algorithms:

 import static org.apache.commons.codec.digest.MessageDigestAlgorithms.SHA_224;
 ...
 byte [] digest = new DigestUtils(SHA_224).digest(dataToDigest);
 String hdigest = new DigestUtils(SHA_224).digestAsHex(new File("pom.xml"));
