The basic usage of verify function is: To know more about JWT structure, visit the article here. HMAC algorithm consists of a secret key and a hash function. The difference is that encryption can be reversed, and hashing can't. You are right to use hashing though - but you don't try to "decrypt" it - you store the hashed value and compare the freshly-hashed user input to that stored hash value. JWT is a common application of this. An example of data being processed may be a unique identifier stored in a cookie. A Hashed Message Authentication Code (HMAC) is a cryptographic artifact for determining the authenticity and integrity of a message object, the usage of a symmetric key and a hash (message-digest). aes-128-cfb.
