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. For the sake of simplicity, let us pretend for this example that there are only the lower case letters a -… Read More »Asymmetric Encryption

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: As pictured, if we start with the plain text hello, and use a Symmetric encryption algorithm of simply rotating the… 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, or Clear text. After the data has been encrypted, it is referred to as Cipher text. The Cipher text should be completely… Read More »Confidentiality
