Hash Generator
Generate MD5, SHA-1, SHA-256, SHA-384, and SHA-512 hashes from any text — or verify that a hash matches.
Generate
Verify a Hash
Paste a hash and the original text — the tool auto-detects the algorithm and tells you if they match.
What is the Hash Generator?
A cryptographic hash function converts any input into a fixed-length fingerprint called a hash or digest. The same input always produces the same hash, but a single character change completely alters the result. Hash functions are one-way: you cannot reverse a hash back to the original text. This tool generates five widely-used hashes at once: MD5 (32 hex chars), SHA-1 (40), SHA-256 (64), SHA-384 (96), and SHA-512 (128). MD5 and SHA-1 are fast but deprecated for security; SHA-256 and SHA-512 are the current standard for integrity checking and digital signatures.
How to use it

Frequently asked questions
What is a hash used for?
Hashes verify data integrity (file checksums), store passwords securely (with a slow algorithm like bcrypt or Argon2), generate digital signatures, and deduplicate content. Developers also use them to compare large strings quickly or build cache keys.
Is MD5 safe to use?
MD5 and SHA-1 are cryptographically broken and should not be used for security purposes such as password storage or digital signatures. They are still acceptable for non-security checksums like verifying a file download.
Will the same input always give the same hash?
Yes. Hash functions are deterministic: identical input always produces identical output. Even one extra space or a different letter casing produces a completely different hash.
Can I reverse or "decrypt" a hash?
No. Hash functions are one-way by design — there is no algorithm to recover the original text from a hash. What you can do is verify: if you still have the original text, paste it alongside the hash and this tool confirms instantly whether they match.
Is my text stored or sent anywhere?
No. The text you submit is used only to compute or verify the hashes and is not saved or shared.
