"WebOct 10, 2024 · HMAC helps authenticate a message that one device sends to another. HMAC is like a cyclic redundancy check or CRC with a few differences. The secret key is configured on both devices, so it is ‘known’. The secret key is never transmitted across the unsecure medium. The message is sent in the clear so it is known by both devices.

hash - What does it mean that Hmac is secure?

WebMD5 produces a 128-bit (16 byte) message digest, which makes it faster than SHA1 or SHA2. This is the least secure algorithm. HMAC-SHA1 (Hash Message Authentication Code — Secure Hash Algorithm 1) SHA1 produces a 160-bit (20 byte) message digest. Although slower than MD5, this larger digest size makes it stronger against brute force attacks. WebApr 11, 2024 · 文章标签： shiro. 版权.
