It was never designed for cryptography. However it is sometimes used in protocols such as WEP. When used for cryptographic purpose, it can lead to compromising the security of the exchanges. In this article one of possible attack against use of CRC in cryptography will be detailed.</p>SinopleThu, 13 May 2021 13:00:00 +0200tag:None,2021-05-13:crc-is-not-cryptography.htmlArticlecrccryptographyintegrityone-time padstream cipherbackup-important-files-with-rsync-and-crontab.html<p>You may have important files in your computer such as a password manager database, gpg key, bitcoin private keys. There is a risk of loss or modification of these files for multiple possible reason such as hardware failure. If that happen it may have a big impact for you. In this article some simple backup method for Linux will be presented as well as how to automatize them.</p>SinopleTue, 16 Feb 2021 17:00:00 +0100tag:None,2021-02-16:backup-important-files-with-rsync-and-crontab.htmlArticlebackupbashdatalossLinuxone-time-pad-strikes-once-never-twice.html<p>One-time pad, also called Vernam cipher, is often considered as the strongest cryptography as long as you use the key only once. In this article the properties of a one-time pad will be analysed as well as attacks against it.</p>SinopleSat, 30 Jan 2021 22:27:00 +0100tag:None,2021-01-30:one-time-pad-strikes-once-never-twice.htmlArticlecryptographyone-time padhello-world.html<p>This first article will serve as a hello world and verify that everything works correctly.</p>SinopleSun, 24 Jan 2021 23:00:00 +0100tag:None,2021-01-24:hello-world.htmlArticle
