public final Class MD2

extends DigestBase
Class Inheritance
Imports
java.util.Arrays
Implementation for the MD2 algorithm, see RFC1319. It is very slow and not particular secure. It is only supported to be able to verify RSA/Verisign root certificates signed using MD2withRSA. It should not be used for anything else.

Method Detail

cloneback to summary
public Object clone() throws CloneNotSupportedException

Overrides sun.security.provider.DigestBase.clone.

Doc from java.security.MessageDigestSpi.clone.

Returns a clone if the implementation is cloneable.

Exceptions
CloneNotSupportedException:
if this is called on an implementation that does not support Cloneable.
implCompressback to summary
pack-priv void implCompress(byte[] b, int ofs)

Implements abstract sun.security.provider.DigestBase.implCompress.

Doc from sun.security.provider.DigestBase.implCompress.

Core compression function. Processes blockSize bytes at a time and updates the state of this object.

implDigestback to summary
pack-priv void implDigest(byte[] out, int ofs)

Implements abstract sun.security.provider.DigestBase.implDigest.

Doc from sun.security.provider.DigestBase.implDigest.

Return the digest. Subclasses do not need to reset() themselves, DigestBase calls implReset() when necessary.

implResetback to summary
pack-priv void implReset()

Implements abstract sun.security.provider.DigestBase.implReset.

Doc from sun.security.provider.DigestBase.implReset.

Reset subclass specific state to their initial values. DigestBase calls this method when necessary.
