How to encrypt a text or any other media using RSA cryptography in C# ? .
Do i need to use any external libraries or are there any in-build stuff ? A small sample code will help!

RSA is the standard cryptographic algorithm on the Internet. The method is publicly known but extremely hard to crack. It uses two keys for encryption. The public key is open and the client uses it to encrypt a random session key.
The RSA algorithm (Rivest-Shamir-Adleman) is the basis of a cryptosystem -- a suite of cryptographic algorithms that are used for specific security services or purposes -- which enables public key encryption and is widely used to secure sensitive data, particularly when it is being sent over an insecure network such as ...
Currently the standard is 2,048-bit RSA keys, up from 1,024, which was allowable until just a few years ago. Some organizations use 3,072-bit and 4,096-bit keys, but as RSA key sizes grow, the amount of security provided by them isn't commensurate to the amount of computational power that will be required to use them.
The RSA private key is used to generate digital signatures, and the RSA public key is used to verify digital signatures. The RSA public key is also used for key encryption of DES or AES DATA keys and the RSA private key for key recovery.
Use System.Security.Cryptography.RSACryptoServiceProvider.
