"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. " - Simplified sha-1
