Verify a webhook signature
Generate the HMAC output, copy a safe signature report, and inspect payload shape or encoding before changing webhook code.
Generate MD5, SHA-1, SHA-256, SHA-512, HMAC signatures, and a safe signature report locally.
Input / Output
Input, output, and copy actions stay in this main surface. Examples and reference checks are separated below.
Local session
Input state is saved only in this browser so you can restore the last workspace without an account.
Open examples, checks, and related tools only after the primary input/output flow is done.
Verify a webhook signature
Generate the HMAC output, copy a safe signature report, and inspect payload shape or encoding before changing webhook code.
Generate a secure token
Create random session/API/CSRF values, copy a safe token report, compare hashes, and choose identifiers deliberately.
Create a safe password handoff
Generate a password or passphrase, copy a report without the secret value, then choose tokens and hashes deliberately.
Generate a password or passphrase and copy a report without exposing the secret value.
Use random tokens for API, session, CSRF, or webhook secrets instead of reusing passwords.
Use hashes or HMAC only for checksum and signature workflows, not password storage.

## Digest and signature outputs
- MD5: 5eb63bbbe01eeed093cb22bb8f5acdc3 (Legacy checksum only)
- SHA-1: 2aae6c35c94fcfb415dbe95f408b9ce91ee846ed (Legacy; collision-prone)
- SHA-256: b94d27b9934d3e08a52e52d7da7dabfac484efe37a5380ee9088f7ace2efcde9 (Recommended checksum default)
- SHA-512: 309ecc489c12d6eb4cc40f50c902f2b4d0ed77ee511a7c7a9bcd3ca86d4cd86f989dd35bc5ff499670da34255b45b0cfd830e81f605dcf7dc5542e93ae9cd76f (Long digest for stronger comparison)
## Review notes
- Do not use plain hashes for password storage. Use a slow password hashing scheme with salt.
## Safe signature checklist
- Normalize line endings, whitespace, and encoding before comparing with another system.
- Confirm the algorithm and output encoding match the receiving system.
- Never share the HMAC secret itself; share only the signature and verification context.
- Do not treat fast hashes as password storage or encryption.
- Compare the full digest or signature, not only a short prefix.Copy-ready output
