Class SHA5DigestHybrid

  • All Implemented Interfaces:
    java.lang.Cloneable
    public final class SHA5DigestHybrid
extends java.security.MessageDigestSpi
    This class is a facade for the SHA5 message digest algorithm. The alias names "SHA-5" and "SHA5" which refer to this implementation are deprecated, use "SHA512" or "SHA-512" as replacement alias names.

      • clone

        public java.lang.Object clone()
                       throws java.lang.CloneNotSupportedException
        Clones this object.
        Overrides:
        clone in class java.security.MessageDigestSpi
        Throws:
        java.lang.CloneNotSupportedException

      • engineReset

        protected void engineReset()
        Resets the MD5 information back to starting values.
        Specified by:
        engineReset in class java.security.MessageDigestSpi

      • engineGetDigestLength

        protected int engineGetDigestLength()
        Return the digest length in bytes.
        Overrides:
        engineGetDigestLength in class java.security.MessageDigestSpi

      • engineUpdate

        protected void engineUpdate​(byte b)
        Update adds the passed byte to the digested data.
        Specified by:
        engineUpdate in class java.security.MessageDigestSpi
        Parameters:
        b - is the byte to add to the digest.

      • engineUpdate

        protected void engineUpdate​(byte[] input)
        Update adds the passed byte array to the digested data.
        Parameters:
        input - is the byte array to add to the digest.

      • engineUpdate

        protected void engineUpdate​(byte[] input,
                            int offset,
                            int len)
        Update adds the selected part of an array of bytes to the digest. This version is more efficient than the byte-at-a-time version; it avoids data copies and reduces per-byte call overhead.
        Specified by:
        engineUpdate in class java.security.MessageDigestSpi
        Parameters:
        input - array used to update the digest.
        offset - the offset into the array.
        len - the length of the array.

      • engineDigest

        protected byte[] engineDigest()
        Computes and returns the MD5 hash.
        Specified by:
        engineDigest in class java.security.MessageDigestSpi
        Returns:
        the hash.

      • engineDigest

        protected int engineDigest​(byte[] buf,
                           int offset,
                           int len)
                    throws java.security.DigestException
        Computes and returns the MD5 hash in the buffer provided.
        Overrides:
        engineDigest in class java.security.MessageDigestSpi
        Parameters:
        buf - the buffer to put the MD5 hash into.
        offset - is the offset in the buffer into which to copy the hash.
        len - the length of the buffer.
        Returns:
        the length of the hash.
        Throws:
        java.security.DigestException - is thrown when the array is not large enough to hold the digest.
