Hashing Algorithms

Hashing Algorithms
        Hashing is the process of mapping binary data of variable length to a fixed size binary data.

        Applying the same hash function to two identical data structures yields the same result. 

There are two kind of hashing algorithms : with or without a key.
The algorithms without keys are used only to calculate secure hashes for data to ensure integrity, whereas the keyed algorithm are issued together with a key as a MAC for bath integrity.

• ALGORITHM NAME:SHA1   DESCRIPTION :USES SHA ALGO WITH A RESULTING HASH OF 160 BITS
• ALGORITHM NAME: SHA256   DESCRIPTION :USES SHA ALGO WITH A RESULTING HASH OF 256 BITS
• ALGORITHM NAME:SHA 512   DESCRIPTION :USES SHA ALGO WITH A RESULTING HASH OF 512 BITS
• ALGORITHM NAME:SHA 384   DESCRIPTION :USES SHA ALGO WITH A RESULTING HASH OF 384 BITS
• ALGORITHM NAME:MD5   DESCRIPTION :USES MD5 HASH ALGORITHM
• ALGORITHM NAME:RIPEMD160 DESCRIPTION :USES RIPEMD HASH ALGORITHM
