- Constructor Detail
  - MD4Digest
```
MD4Digest()
```
    Standard constructor
  - MD4Digest
```
MD4Digest(MD4Digest t)
```
    Copy constructor.
- Method Detail
  - getAlgorithmName
```
 String getAlgorithmName()
```
    return the algorithm name
    
    Returns:
    
    the algorithm name
  - getDigestSize
```
 int getDigestSize()
```
    return the size, in bytes, of the digest produced by this message digest.
    
    Returns:
    
    the size, in bytes, of the digest produced by this message digest.
  - doFinal
```
 int doFinal(Array<byte> out, int outOff)
```
    close the digest, producing the final digest value. The doFinal call leaves the digest reset.
    
    Parameters:
    
    out - the array the digest is to be copied into.
    
    outOff - the offset into the out array the digest is to start at.
  - reset
```
 void reset()
```
    reset the chaining variables to the IV values.
  - copy
```
 Memoable copy()
```
    Produce a copy of this object with its configuration and in its current state.
    The returned object may be used simply to store the state, or may be used as a similar object starting from the copied state.
  - reset
```
 void reset(Memoable other)
```
    Restore a copied object state into this object.
    Implementations of this method should try to avoid or minimise memory allocation to perform the reset.
    
    Parameters:
    
    other - an object originally copied from an object of the same type as this instance.
