rsa

Hi everyone.

I have BigInteger keys at hand I can copy paste into code. I want to use them. These are a privatekey a publickey and a modulus. I need to calculate the RSA parameters from this. But I suspect there is a library for that which I was unable to find with google. Any ideas? Thanks.

In the past I’ve had a number of ReflectionUtils that used string based expressions… >>> More
