WebJun 6, 2014 · Just was following a tutorial on how to store passwords in a database. they use the following to generate the hashed password: hasher.computeHash = function (source, salt) { var hmac = crypto.crypto.createHmac ("sha1", salt); var hash = hmac.update (source); return hash.digest ("hex"); }; For what ever reason I am getting … WebDec 8, 2024 · Compute an HMAC-SHA512 hash of a string based on the returnUrl and salt query parameters. For more details, check our example code. HMAC(salt + '\n' + returnUrl) Compare the above-computed hash to the value of the sig query parameter. If the two hashes match, move on to the next step. Otherwise, deny the request.

WebAug 1, 2024 · An example of such application is IKEv1 in its "public-key encryption mode", where the "salt" to the extractor is computed from nonces that are secret; similarly, the pre-shared mode of IKEv1 uses a secret salt derived from the pre-shared key. This is because the salt is used as the key for HMAC, and a secret key is a good thing.
