Adding RSA benchmarking

[Benjamin-Loison]

I run both following RSA algorithms on a Intel(R) Core(TM) i9-7920X CPU @ 2.90GHz

• https://github.com/QuasarApp/Qt-Secret#encryption-and-decryption-of-messages
• https://github.com/QuasarApp/Qt-Secret#signature-and-verification-of-the-message-signature

Here are my benchmarking (I would have appreciated to find some on the GitHub so I participate):

RSA in seconds

key size	2048	3072	4096	6144	8192
genPairKey (random process)	2.119	6.974	44.000	31.384	243.044
encode	0.062	0.170	0.437	1.489	3.470
decode	0.096	0.286	0.745	2.449	5.651
sign	1.668	5.503	13.226	44.422	104.119
checkSign	2.906	10.014	23.420	75.711	262.077

To give a comparison with the same CPU on Debian 12 GNOME and also a Linux Mint 22 Cinnamon Framework 13 with i5-1240P using time ssh-keygen -t rsa -b KEY_SIZE -f id_rsa -N '' (real):

key size	2048	3072	4096	6144	8192
i9-7920X	0.154	0.289	0.694	3.942	30.559
i5-1240P	0.146	0.906	0.990	8.995	20.744

Thanks you. may be you can create a pull request with your bench tool ?

[Benjamin-Loison]

I haven't any bench tool I just used: qDebug() << QTime::currentTime().toString("hh:mm:ss,zzz") << " ID 0"; In the README algorithms sorry about that ^^'

So just create a subproject of the main project that will be use this code. Else cannot to add your benchmark test results without benchmark tool.

How big was the data you encoded?

@pH-Valiu

The data was test message. You can find the whole code here.

Unfortunately. But I drop support of this library. See my new library for works with RSA and ECDSA. easyssl
