How To Install xorsearch on Fedora 34
Introduction
In this tutorial we learn how to install xorsearch on Fedora 34.
What is xorsearch
XORSearch is a program to search for a given string in an XOR, ROL, ROT or SHIFT encoded binary file. An XOR encoded binary file is a file where some (or all) bytes have been XORed with a constant value (the key). A ROL (or ROR) encoded file has its bytes rotated by a certain number of bits (the key). A ROT encoded file has its alphabetic characters (A-Z and a-z) rotated by a certain number of positions. A SHIFT encoded file has its bytes shifted left by a certain number of bits (the key) of the second byte becomes the LSB of the first byte, all bits of the second byte shift left, … XOR and ROL/ROR encoding is used by malware programmers to obfuscate strings like URLs.
We can use yum or dnf to install xorsearch on Fedora 34. In this tutorial we discuss both methods but you only need to choose one of method to install xorsearch.
