Introduction to VPN

Cryptography is a technique of securing information and communications through the use of code so that only those persons for whom the information is intended can understand and process it. Thus preventing unauthorized access to information.

What is Cryptography?

 An HMAC (sometimes expanded as either keyed-hash message authentication code or hash-based message authentication code) is a specific type of message authentication code (MAC) involving a cryptographic hash function and a secret cryptographic key. As with any MAC, it may be used to simultaneously verify both the data integrity and authenticity of a message.

HMAC
