Basic but pure DES implementation in Python I have written it for fun because nothing else. How it works ? Everything is made within a class called "des". This class can be instanciated once and used to cipher and decipher multiple datas. It also support padding using the PKCS5 specificat...
[ANSWERED] Anomaly with implementation of algorithm for reversing a number (integer) Hi SoloLearners, It all started as I read this post https://www.sololearn.com/Discuss/3064986/?ref=app - asking how to reverse a number (integer). I understand this could be easy in Python sh...
