What is Cryptographic Hashing?
Cryptographic hashing is a one-way mathematical function that turns any amount of data into a fixed-length string of characters (the hash). It's designed to be irreversible, meaning you cannot recover the original data from its hash.
The SHA-2 (Secure Hash Algorithm 2) family, including SHA-256 and SHA-512, is widely used in certificates, blockchain, and secure file validation. This tool calculates these hashes locally in your browser using the .NET standard library, ensuring your sensitive strings never leave your machine.
