If you need the information to be secure HMAC should be applied to ciphertext instead. While it is possible to apply HMAC to plaintext, this is only okay if the purpose of using HMAC is for message authentication purpose. Receiver must then recreate hash using information prior calculation and match the resulting has to provided hash value. Sender must provide calculated hash value signed with such secret for receiver to validate. HMAC Application in Network CommunicationĪbove process can be utilized as a validation tool between parties by following steps.īoth receiver and sender parties must know of ‘secret’ (key used to sign HMAC hash). Custom Post Type UI I previously talked about how easy it is to use an online generator to create your own custom plugin, but I still use Custom Post Type UI as it is there when quick changes are needed.

WP-CodeBox provides clean syntax highlighting and AJAX advanced features for embedding source code within pages or posts.It support wide range of popular languages highlighting. Hmac.digest('') // calculates all data updated into a string Hmac.update('') // takes input data and update calculation const hmac = createHmac('', '') // returns Hmac object Hmac object can then be used to generate cryptographic HMAC hash when provided with key and desired algorithm. Crypto’s “createHmac” method allows easy implementation of HMAC by returning Hmac object. Node.js has built-in module called “crypto” which is a wrapper for OpenSSL cryptographic functions.
