I'm trying to create a URL that is made up of a set of parameters and a token that is generated using a MD5 hash function. I'm a beginner at hashing and using salt to generate this token. I've got the secret key(which i believe is the salt) and the string I need to hash. I believe that is all I need in order to create my token. Would you have any suggestions or links on how to generate the token I need? Please let me know if you need more information.
