Hash Generator

Processing: API. Processed by cent-ai's API: sent to our server, held in memory, never stored.

Generate an MD5, SHA-1, SHA-256, or SHA-512 hex digest of text. Nothing you paste here is stored or logged.

How to use it

  1. Choose an algorithm (SHA-256 by default).
  2. Paste or type text into the input field.
  3. The hex digest appears automatically, or select “Generate hash” to run it immediately.
  4. Copy the result to your clipboard.

Example

Select “Use example” above to load a sample value.

Privacy and security

  • Input is sent to our API only to be hashed; it is never persisted or logged.
  • Requests are not included in analytics or error reporting.
  • Request bodies are limited in size to keep the service responsive for everyone.

Limitations

  • MD5 and SHA-1 are included for legacy compatibility only — both are cryptographically broken for collision resistance.
  • This tool hashes text input, not files.
  • Very large payloads may be rejected to protect the service.

FAQ

Which algorithm should I use?

SHA-256 or SHA-512 for anything that matters — checksums you'll rely on, integrity checks, deduplication. MD5 and SHA-1 are offered for compatibility with legacy systems only; both have known collision weaknesses and shouldn't be used where collision resistance matters.

Is my input stored anywhere?

No. Input is processed in memory to produce the digest and is not saved or logged.

Can I reverse a hash back to the original text?

No. Hashing is one-way by design. This tool generates digests; it does not perform lookups against precomputed hash tables.
