Constructor Details

MD5Digest

public MD5Digest()

Standard constructor

MD5Digest

public MD5Digest(MD5Digest t)

Copy constructor. This will copy the state of the provided message digest.

Method Details

getAlgorithmName

public String getAlgorithmName()

Description copied from interface: Digest

return the algorithm name

Returns:

the algorithm name

getDigestSize

public int getDigestSize()

Description copied from interface: Digest

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

public int doFinal(byte[] out,
 int outOff)

Description copied from interface: Digest

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

public void reset()

reset the chaining variables to the IV values.

Specified by:

reset in interface Digest

Overrides:

reset in class GeneralDigest
