Simplified sha-1

WebbSHA-1 is a mathematical algorithm to hash a certain string. It creates a one-way change from the source string to the result. It is commonly used for security and data loss, but there may be other cases. Computer programs exist to crack SHA-1 hashes by hashing random strings and storing the result. WebbSHA-1 It is a 160 bit or a 20-byte long hash-based function-based encryption mechanism that is used to resemble the year-old MD5 algorithm.
