Class ConcurrentMessageDigest

  • public class ConcurrentMessageDigest
    extends java.lang.Object
    A thread safe wrapper around MessageDigest that does not make use of ThreadLocal and - broadly - only creates enough MessageDigest objects to satisfy the concurrency requirements.

      • init

        public static void init​(java.lang.String algorithm)
        Ensures that digest(String, byte[][]) will support the specified algorithm. This method must be called and return successfully before using digest(String, byte[][]).
        algorithm - The message digest algorithm to be supported
        Throws: - If the algorithm is not supported by the JVM
