What is symmetric-key encryption?

Public key encryption is a part of the public key cryptography. There are two types of public key encryption namely:

Symmetric key encryption and Asymmetric key encryption.

In this article we focus up on the former type i.e., the symmetric key encryption.

– Symmetric key encryption is done using the symmetric – key algorithms. […]

What is a Secure Socket Layer?

– Cryptography cannot be achieved without cryptographic protocols. – These protocols are responsible for providing the communication security on internet. – Examples of such protocols are transport layer security (TLS) and secure sockets layer (SSL).

In this article we talk about the latter one i.e., the secure sockets layer. – For authenticating the key exchange, […]

What is public-key encryption?

A cryptographic system requires two individual keys and is commonly called as the public-key cryptography. These two keys are:

Public key The secret key

– There exists a mathematical link between these two keys even though they are different. – Out of these, one is used for encrypting or locking the plain text and other […]

What is Advanced Encryption Standard (AES)?

– The AES or advanced encryption standard like the data encryption standard is also a specification established by the NIST (national institute of standards and technology, U.S.) for encrypting the electronic data. – Vincent Rijmen and Joan Daemen are the two Belgian cryptographers who developed the Rijndael cipher that serves as a basis for the […]
