Frequently Asked Questions
- What is a hash and what does this hash generator do?
- A hash is a fixed-size fingerprint of data. This tool generates MD5, SHA-1, SHA-256, SHA-384, and SHA-512 hashes from any text. All hashing runs in your browser — no server.
- Which hash algorithm should I use?
- Use SHA-256 or SHA-512 for security (passwords, signatures). MD5 and SHA-1 are legacy; use them only for checksums or compatibility. The generator supports all of these.
- Is my input sent to a server when generating hashes?
- No. Hashing is done entirely in your browser. Your text never leaves your device.
