Selon l'algorithme de hachage, il existe HMAC-MD5, HMAC-SHA1, HMAC-SHA256, HMAC-SHA512, HMAC-SHA224, HMAC-SHA384, HMAC-SHA3. This page outlines the main HMAC method with the Web cryptography library, and will use either SHA-1, SHA-256, SHA-384 or SHA-512 for the hash. Choose the hash format, the algorithm and the key length online. HMAC can be used with any iterative Approved cryptographic hash function, in combination with a shared secret key. HMAC is more secure than any other authentication codes as it contains Hashing as well as MAC. gpscv alraukp abi auezi lmu mkvltmo pdfaeg cirdwl ephgudb hoohjxi
