تولیدکننده HMAC چیست؟

موارد استفاده رایج

• Verify an incoming webhook by recomputing the HMAC of the raw request body with your endpoint's signing secret and comparing it to the provider's signature header.

• Check a Stripe webhook locally: HMAC-SHA256 the timestamped payload with your whsec_ secret to confirm your verification logic before deploying.

• Debug a mismatched signature by pasting the exact bytes your server and client each signed to see which side is wrong.

• Generate a quick integrity tag for a config file or message so a teammate with the same key can confirm it was not altered in transit.

• Teach or learn how HMAC differs from a bare hash by toggling algorithms and watching the digest length change.

• Sanity-check a single HMAC step of a larger signing scheme (such as one round of the AWS SigV4 key-derivation chain) during development.
