This SHA-256 generator is a useful tool for securing sensitive data such as password before saving into the database.
What is an SHA-256?
SHA-256 is a message-digest algorithm. It’s used to compute a hash value in cryptography. So what’s an hash function then? Simply put, a hash function takes a block of data and returns a fixed-size bit string (hash value). The data used by hash functions is referred to as a “message”, while the computed hash value is referred to as the “message digest”.
SHA-256 is one of the successor hash functions to SHA-1, and is one of the strongest hash functions available.
SHA-256 is a type of hash function commonly used in Blockchain. A hash function is a type of mathematical function which turns data into a fingerprint of that data called a hash. It’s like a formula or algorithm which takes the input data and turns it into an output of a fixed length, which represents the fingerprint of the data.
