Secure Hash Algorithms (SHA) are a family of cryptographic hash functions that are used to encrypt data. SHA is a modified version of MD5. SHA's hash function uses bitwise operations, modular additions, and compression functions to produce a fixed-size string that looks different from the original data. A small change to the original data produces a different encrypted output, which is known as the avalanche effect. SHA's primary goal is to produce a unique hash value for each input message. SHA-1 makes sure that two different messages are unlikely to produce the same hash value, making...
