Hi,
I've created a RSA application for MVS: RSA-1024 with SHA56 using the native
functions (RSA_sign, SHA256, ...). Here u can find the code:
http://www.nabble.com/file/p26096986/rsa.cpp rsa.cpp
With an IA-32 Pentium M 1.5 GHz, I'm in the order of microseconds:
- signature: 3.6 ms
- verify: 0.19 ms
Now you can try the EVP interface.
