i want to know how many RSA 1024 bit long key decryption can a regular pentium4 computer do per second ? how to calculate RSA performance and determine its remaining time ?
Good link: Crypto++ for pentium 4
Milliseconds/Operation Megacycles/Operation RSA 1024 Encryptio 0.09 0.27 RSA 1024 Decryption 2.28 6.68
CPU frequency of the test platform is 2.93e+009 Hz.
I think the performance depends on the language, library and CPU architecture.
