Public Key (Asymmetric) Cryptography Public-key cryptography, or asymmetric cryptography, is the field of cryptographic systems that use pairs of related keys.Each key pair consists of a private key and a corresponding public key.Key pairs are generated with cryptographic algorithms. The main uses of asymmetric cryptography are : – Encryption (public key)Anyone with a public key …

Stallman : An Introduction to GCC The process of translating source code into an executable program is called “compiling the program” or just “compiling”.We usually view the compilation process as a single action and generally refer to it as such.Nevertheless, a modern …
Computers can only understand binary language (sequences of instructions made of 1s and 0s) called machine code or machine language. To command a computer you need to speak its language.Not all the computers “speak the same way”, there are different technical implementations and representation of instructions. The instructions that a machine can understand is called …
