Package anlavn.hash

Class MD5

java.lang.Object

anlavn.hash.MD5

@Deprecated
public class MD5
extends Object

Deprecated.

The security of the MD5 hash function is severely compromised. A collision attack exists that can find collisions within seconds on a computer with a 2.6 GHz Pentium 4 processor (complexity of 2^24.1). Further, there is also a chosen-prefix collision attack that can produce a collision for two inputs with specified prefixes within seconds, using off-the-shelf computing hardware (complexity 2³⁹).

The MD5 class supports object and string encryption, decryption it is impossible. MD5 uses the Message-Digest algorithm 5 cryptographic hash function with a 128-bit long hash value.
Make sure your object class was "implements Serializable".
