Frequently Asked Questions
- What hash algorithms are supported?
- MD5, SHA-1, SHA-256, SHA-384, and SHA-512. SHA-256 and SHA-512 are recommended for security-sensitive use cases.
- Is my text sent to a server?
- No. All hashing runs entirely in your browser using Web Crypto API (and local MD5 for compatibility).
- What is a hash used for?
- Hashes create a fixed-size fingerprint of data. Developers use them for checksums, cache keys, API signatures, and verifying file integrity.
- Is MD5 still safe?
- MD5 is not cryptographically secure for passwords or signatures. Use it only for legacy checksums. Prefer SHA-256 or SHA-512 for security.
