#️⃣ Hash Generator
Generate MD5, SHA-1, SHA-256, SHA-384, SHA-512 and CRC32 hashes from text instantly.
About the Hash Generator
This free online tool generates cryptographic hashes server-side using PHP's native
hash() function. A hash is a fixed-size fingerprint of your input — the same
input always produces the same hash, but you cannot reverse a hash back into the original text.
- MD5 — fast, 128-bit. Broken for security purposes; still used for checksums and non-security deduplication.
- SHA-1 — 160-bit. Deprecated for security use due to known collision vulnerabilities.
- SHA-256 — 256-bit, part of the SHA-2 family. Widely used and considered secure (e.g. in Bitcoin, TLS certificates).
- SHA-384 / SHA-512 — larger variants of SHA-2, offering a bigger security margin.
- CRC32 — not cryptographic at all; used only for basic error-checking (e.g. ZIP files), never for security.
Important: Never use MD5 or SHA-1 alone to store passwords. For password storage, use a dedicated algorithm designed for that purpose, such as bcrypt, Argon2 or PBKDF2, which add salting and computational cost to resist brute-force attacks.
