Simply, what does 128-bit encryption mean? How do you achive it in code? What about 64-bit? Possibly 4096-bit ( slow, but possible? ) ? I am newbie to coding Crypto apps. Please give me a bit of help, any will be appriciated.

basically, the key size represents the maximum possible security that the cryptographic algorithm can provide, since the slowest possible method would be brute-force. however the provided security may be lower if there is a lower know attack complexity.

some good reads on crypto are here:

some good APIs for crypto (C & C++): CryptoPP, Botan, and (perhaps obviously) OpenSSL.

other than that, wikipedia is decent for understanding crypto terminology.
The whole secret of existence is to have no fear. Never fear what will become of you, depend on no one. Only the moment you reject all help are you freed.
