Abstract Hash value plays a significant role in establishing the authenticity and integrity of data/evidence in the digital world particularly in Cryptography, Data Analyses and Forensic Imaging etc. A hash value (or simply hash), also called a message digest, is a number generated from a string of text. The hash is generated by a formula in such a way that it is extremely unlikely that some other text will produce the same hash value ( No two data can theoretically have same Hash Value ), the hash value – is produced that identifies the contents of the file. If the contents are modified in any way, the value of the hash will also change significantly.

Online Hash Calculator lets you calculate the cryptographic hash value of a string or file ,A cryptographic hash is like a signature or fingerprints for files.
