SHA-256 Hash Generator

Generate secure SHA-256 hashes for any text input. 100% free, secure, and hashed locally in your browser so your data is never sent to a server.

What is SHA-256?

SHA-256 (Secure Hash Algorithm 256-bit) is a cryptographic hash function that generates a fixed-size 256-bit (32-byte) hash. It is one of the most widely used hashing algorithms today and is a key component of many security protocols and technologies, including SSL/TLS, IPsec, and Bitcoin.

Is it secure?

SHA-256 is currently considered very secure. It is "collision-resistant," meaning it is practically impossible to find two different inputs that produce the same hash. Unlike encryption, hashing is a one-way process; you cannot "decrypt" a hash back into its original text.

Why use Hashing locally?

Many online tools send your sensitive data to their servers to generate hashes. Our tool runs 100% in your browser using the Web Crypto API. Your input text never leaves your computer, ensuring absolute privacy for your passwords, keys, or private data.
