Pertanyaan yang sering diajukan
Quick answers.
›What is HMAC?
Hash-based Message Authentication Code — a way to verify a message hasn't been tampered with using a shared secret. Common in webhook signing.
›Is HMAC encryption?
No — HMAC is authentication. The message itself is in cleartext; HMAC just lets the receiver verify it came from someone with the same secret.
›Which algorithm should I use?
HMAC-SHA256 is the modern default. HMAC-SHA1 is still common in older systems but should be avoided for new work.
›Is my secret sent to a server?
No — generation runs entirely in your browser via the Web Crypto API.
›Is the generator free?
Yes — fully free, no signup.
