I'm looking for the 3 parameters for the RSA algorithm in hexadecimal:

the module and two exponents.

I would like to use RSA with about 512 bit.

It is better a little number for the decrypt exponent to decrypt fast.

The RSA I have use hexadecimal strings and keys.

It is ok also to find decimal parameters, but after that I must

convert big numbers into hexadecimal and I don't find a correct

converter.

Have you searched for multi-precision math libraries like GMP?

You might also look at libtommath (http://math.libtomcrypt.com/).

You might need to use the math library and write your own converter -

but the important part is the multi-precision library - and you should

easily be able to do that.
