Google recently released new features for its SaaS data warehouse BigQuery which include column level encryption functions and dynamic masking of information. Specifically, dynamic masking of informat ...

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.

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.

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.

This paper presents a design of data encryption and decryption in a network environment using RSA algorithm with a specific message block size.

Akira ransomware dynamically generates unique encryption keys for each file using four different timestamp seeds with nanosecond precision and hashes through 1,500 rounds of SHA-256.
