How do I classify my RSA encryption strength? So I generated 2 1024 bit prime numbers, I generated N and got a 2048 bit number, does that make my encryption 2048 bit or 1024 bit?
The key length specified for RSA is the length of the modulus $n$ in bits. Thus, if you generate $n=p*q$ and get a 2048 bit modulus, your RSA encryption is 2048 bit.
