MD2
final class MD2 extends MessageDigest (Code)
Implements the MD2 hashing algorithm as described in IETF RFC 1321 (see http://www.ietf.org/rfc/rfc1321.txt)



Constructor Summary
 MD2()
     Create an MD2 digest object.

Method Summary
public  Objectclone()
     Clones the MessageDigest object.
public  intdigest(byte[] buf, int offset, int len)
     Completes the hash computation by performing final operations such as padding.
public  StringgetAlgorithm()
     Gets the message digest algorithm.
public  intgetDigestLength()
     Gets the length (in bytes) of the hash.
public  voidreset()
     Resets the MessageDigest to the initial state for further use.
public  voidupdate(byte[] inBuf, int inOff, int inLen)
     Accumulates a hash of the input data.


Constructor Detail
MD2
MD2()(Code)
Create an MD2 digest object.




Method Detail
clone
public Object clone()(Code)
Clones the MessageDigest object. a clone of this object



digest
public int digest(byte[] buf, int offset, int len) throws DigestException(Code)
Completes the hash computation by performing final operations such as padding. The digest is reset after this call is made.
Parameters:
  buf - output buffer for the computed digest
Parameters:
  offset - offset into the output buffer to begin storing the digest
Parameters:
  len - number of bytes within buf allotted for the digest the number of bytes placed into buf
exception:
  DigestException - if an error occurs.



getAlgorithm
public String getAlgorithm()(Code)
Gets the message digest algorithm. algorithm implemented by this MessageDigest object



getDigestLength
public int getDigestLength()(Code)
Gets the length (in bytes) of the hash. byte-length of the hash produced by this object



reset
public void reset()(Code)
Resets the MessageDigest to the initial state for further use.



update
public void update(byte[] inBuf, int inOff, int inLen)(Code)
Accumulates a hash of the input data. Continues an MD2 message-digest operation, processing another message block, and updating the internal context.
Parameters:
  inBuf - input buffer of data to be hashed
Parameters:
  inOff - offset within inBuf where input data begins
Parameters:
  inLen - length (in bytes) of data to be hashed
