MD5 ENCODING IN JAVA HOW TO
This tutorial demonstrates how to generate MD5 and SHA hash values from String or file using Java. SecretKeyFactory keyFactory = SecretKeyFactory.getInstance( " DES") The Java platform provides two implementation of hashing functions: MD5 (produces 128-bit hash value), SHA-1 (160-bit) and SHA-2 (256-bit). Create a key factory and use it to turn the DESKeySpec into // a SecretKey object Create a DES key object specification from the raw dataĭESKeySpec dks = new DESKeySpec(Hex.fromString(keyString)) procedure MD5(s) : return MD5 hash of message s. The DES algorithm requires a trusted source of random bits procedure testMD5(s,rh) compute the MD5 hash and compare it to.
