I create a program on a microntroller (which does not run any OS), and I can't find any library in C which can give me a RSA (PKCS#1) key generator (public and private). I suppose that OpenSSH isn't an option because it's link to Linux or Unix. I found some SSH implementation, but it supports only the client side (encoding through a public key). RSA algorithm is asymmetric cryptography algorithm. Asymmetric actually means that it works on two different keys i.e. Public Key and Private Key. As the name describes that the Public Key is given to everyone and Private key is kept private. RSA is a public-key cryptosystem developed by MIT professors: Ronald L. Rivest, Adi Shamir, and Leonard M. Adleman in 1977 in an effort to help ensure internet security. As Steve Burnett of RSA Data Security, Inc. Described it, a cryptosystem is simply an algorithm that can convert input data into something unrecognizable (encryption),.

(C) RSA Encrypt and Decrypt Strings. C sample code to RSA public-key encrypt and decrypt strings using public and private keys. RSA (Rivest–Shamir–Adleman) is an algorithm used by modern computers to encrypt and decrypt messages. It is an asymmetric cryptographic algorithm. Asymmetric means that there are two different keys. This is also called public key cryptography, because one of the keys can be given to anyone. The other key must be kept private.
