Supports

• SHA224
• SHA256
• SHA384
• SHA512

• SHA512/256

API for Each Digest

• public static hash(byte[] message) - Hashes the given message and return hex string.

• public static final BLOCK_SIZE - SIZE of each chunk in which processing happens.

• public static final DIGEST_SIZE - SIZE of digest in bytes.

• New Digest can be created using new operator

  • new DIGEST() - creates a new DIGEST
  • new DIGEST(byte[] message) - creates a new DIGEST with immediate processing of message
  • update(byte[] message) - updates(appends) the given message (used if the original string is too large we can process it in chunks)
  • finals() - Completes the DIGEST (after this function call update won't be accepted)
  • getDigest() - return the digest till now in bytes.
  • getHexDigest() - return the digest till now in Hex string.
  • resetDigest() - resets the whole DIGEST context
