Earlier, we learned that Symmetric encryption is an encryption scheme that uses the same key to encrypt and decrypt. Conversely, Asymmetric encryption, uses different keys to encrypt and decrypt. Lets take a look at a simple example.… Read More »Asymmetric Encryption
The first concept we need to discuss in our exploration of Cryptography is that of a Hashing Algorithm. A Hashing Algorithm is a mathematical formula that takes a Message of arbitrary length as input and… Read More »Hashing Algorithm
In the world of secured communications, Message Integrity describes the concept of ensuring that data has not been modified in transit. This is typically accomplished with the use of a Hashing algorithm. We learned earlier what a Hashing Algorithm… Read More »Message Integrity
We learned earlier that Symmetric encryption is an encryption scheme that encrypts and decrypts using the same secret key. Now we will explore a bit further into what that involves. Let’s start with a simple example:… Read More »Symmetric Encryption
Confidentiality is the concept of hiding or scrambling your data so that only the intended recipient has access. This is typically accomplished by some means of Encryption. Data before it has been encrypted is referred to as Plain text,… Read More »Confidentiality
