Creating RSA key from given prime numbers

2008-07-17 Thread Didier Stevens 
For educational purposes, I want to use openssl to create an RSA key
with prime numbers I provide.

Is this possible with an openssl command, or do I have to adapt the source code?

From command line (openssl executable) this is not possible.

You can write a little program in C using OpenSSL library.
You should know p, q and e numbers and have to calculate some other 
numbers: n, d, dmp1, dmq1, iqmp.

Example code is in /crypto/rsa/rsa_gen.c file.
