I am trying to write a challenge respond script what i have figured out so far is that it is using rsa pkcs1 however, .. does anyone know how i would use this in pure tcl, don't want to use binary cause i already know how to do that, .. however i'm wondering how to use pure tcl in tcl challenge responds.. but i can't seem to determine which lib i should use.
Keep in mind, that building a pure-tcl implementation will not be practical without the bignum extension or tcl 8.5, due to the size of the numbers in the arithmetics
