Which hash algorithm should I use: SHA-256, SHA-384, or SHA-512?

SHA-256 is the most widely used and sufficient for most purposes; SHA-384 and SHA-512 produce longer digests and are used where an even larger security margin or 64-bit-optimized performance is preferred.

Is MD5 or SHA-1 available?

This tool uses the browser's native Web Crypto API, which only implements the modern SHA-2 family (SHA-256/384/512) -- MD5 and SHA-1 are considered cryptographically broken and are intentionally not offered.

How It Works

Uses your browser native `crypto.subtle.digest` to calculate cryptographic hashes without external libraries.

Frequently Asked Questions

Common questions about calculations, assumptions, and edge cases.

No -- cryptographic hash functions are one-way by design; there is no way to recover the original input from a SHA-256/384/512 hash, only to verify a new input produces the same hash.
