statistics circle for analysing byte entropy in files

In a previous post I introduced triops, a multiplatform cmdline encryption tool using CHACHA20 algorithm. In general, any encryption algorithm should produce a reasonably high entropic output no matter the input (plain text) at hand — this is in order to be aligned with concepts like Entropic security and Semantic security, very important in modern … Continue reading

triops: a multiplatform cmdline encryption tool using CHACHA + KECCAK

I’ve developed in C a simple command line tool for encryption/decryption of files, which I have named triops. It uses CHACHA20 as algorithm for encryption/decryption and KECCAK-512 as hash algorithm. Source code is available at github. Check github for latest changes! Executables for some platforms (linux, Windows, HP-UX, Solaris, and Android) are available here. For … Continue reading
