What is SHA-256?
SHA-256 (Secure Hash Algorithm 256-bit) produces a fixed 64-character hexadecimal hash from any text input. It runs entirely in your browser using the Web Crypto API (SubtleCrypto) — your data never leaves your device.
Common uses
- File integrity verification — checksum downloads, software packages, and firmware.
- Password hashing (with salt) — store hashed passwords instead of plain text.
- Digital signatures & certificates — TLS/SSL, code signing, blockchain transactions.
- API keys & tokens — generate unique identifiers from input data.
Quick tips
- SHA-256 is the recommended general-purpose hash — secure, fast, well-supported.
- Hashes are one-way — you cannot recover the original text from a hash.
- A SHA-256 hash is always 64 hexadecimal characters long, regardless of input size.
- Need a different hash? Try the MD5 Generator, all-in-one Hash Generator, or SHA-512 Generator.
