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.

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 ...

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.

4. Use One-Way Hash Functions For highly sensitive information such as secret keys, passwords, PIN and security questions, run a one-way hash function on the message with a cryptographic key.

The articles detail a decade-long NSA project to attack encryption standards from every angle, employing server farms for brute-force decryption, using malware to intercept messages before ...
