GeneralDigest
protected GeneralDigest()
- Standard constructor
GeneralDigest
protected GeneralDigest(GeneralDigest t)
- Copy constructor. We are using copy constructors in place
of the Object.clone() interface as this interface is not
supported by J2ME.
update
public void update(byte in)
- Description copied from interface:
Digest
- update the message digest with a single byte.
- Specified by:
update in interface Digest
- Following copied from interface:
org.bouncycastle.crypto.Digest
- Parameters:
in - the input byte to be entered.
update
public void update(byte[] in,
