| MD5 | | final public class MD5 extends MessageDigest (Code) | | This class implements the Message Digest 5 algorithm (MD5) as
defined in RFC-1321.
Note: even if standard Java 1.1 APIs already provide a
MD5 implementation, this class is used on those Java runtime
environments (like Kaffe) where the package
java.security is highly improbable to be found.

| Constructor Summary | |
| public | MD5()
Creates the algorithm and reset its state. |
| Method Summary | |
| public void | append(byte[] block, int offset, int length)
Append another block of specified length to the message
starting at the given offset. | | public byte[] | digest(byte[] block, int offset, int length)
Appends a message block with specified length starting from the
given offset, and return its message digest. | | final public static void | main(String[] ignored)
| | public void | reset()
Resets the state of the class. | | public static byte[] | toBytes(long n)
Converts a long to a 8-byte array using low order first.
Parameters:
n - A long. |
| padding | | static byte padding(Code) | | MD5 Functions **********************
|
| MD5 | | public MD5()(Code) | | Creates the algorithm and reset its state.
|
| append | | public void append(byte[] block, int offset, int length)(Code) | | Append another block of specified length to the message
starting at the given offset.
Parameters:
block - A byte[].
Parameters:
offset - An int.
Parameters:
length - An int. |
| digest | | public byte[] digest(byte[] block, int offset, int length)(Code) | | Appends a message block with specified length starting from the
given offset, and return its message digest.
Parameters:
block - A byte[].
Parameters:
offset - An int.
Parameters:
length - An int. |
| reset | | public void reset()(Code) | | Resets the state of the class. Beware: calling this
method erases all data previously inserted.
