state. Any Update() causes this to be set to null.

Transform
private void Transform(MD5State state, byte[] buffer, int shift)
Update
public void Update(MD5State stat, byte[] buffer, int offset, int length)
- Updates hash with the bytebuffer given (using at maximum length bytes from
that buffer)
Update
public void Update(byte[] buffer,
int offset,
int length)
- Plain update, updates this object
Update
public void Update(byte[] buffer,
int length)
Update
public void Update(byte[] buffer)
- Updates hash with given array of bytes
Update
public void Update(byte b)
- Updates hash with a single byte
Update
public void Update(java.lang.String s)
- Update buffer with given string.
Update
public void Update(int i)
- Update buffer with a single integer (only & 0xff part is used,
as a byte)
Encode
private byte[] Encode(int[] input,
int len)
Final
public byte[] Final()
- Returns array of bytes (16 bytes) representing hash as of the
current state of this object. Note: getting a hash does not
invalidate the hash object, it only creates a copy of the real
state which is finalized.
asHex
public static java.lang.String asHex(byte[] hash)
- Turns array of bytes into string representing each byte as
unsigned hex number.
asHex
public java.lang.String asHex()
- Returns 32-character hex representation of this objects hash
