Fig. 2: Symmetric cryptography. Asymmetric Cryptography – Also known as public key cryptography, uses a pair of private key/public key for encryption and decryption. If a resource, whether it’s the ...

Most Linux users know vim as a text editor that descended from vi. It can also function as a tool for encrypting text files. In this post, we examine how this is done and how to reverse the process.

In this paper, the authors provide with an encryption decryption algorithm with secure strength, bringing failure to the intruder effort to break the cipher.

Encryption-decryption is one of those techniques which are quite popular. But, the complexity which is involved in this technique doesn’t allow its users to apply it in a simpler way.

Cryptography is the art of keeping information secret and safe by transforming it into form that unintended recipients cannot understand. It makes secure data transmission over the internet possible.

With this, either exactly the same function does encryption and decryption, or one function does encryption and a similar, but different one does decryption. The most popular algorithm is called AES.
