Hello,

Can some one help me to how can i choose the m value in the IP-Core RSA 512 bits ?

you find it in the attached file

thanks to help

Do you have the pair of keys + the module required to perform RSA operations?

m is THAT module.

x^y mod m is a modular exponentiation, therefore an RSA operation.

I suggest you to read a complete description of RSA, you can start here:

http://en.wikipedia.org/wiki/RSA

You seem to do not understand it very well.

notice that in this description, the modular exponentiation is shown as m^c mod n

the m that you are asking for is the n in this expression, you can see it is the same one that i wrote above, only the variable names changes.
