Re: Montgomery constants

uage, but is this the same. I thought the references to Montgomery constants in the RSA structure would be helpfull, bul I don't know how to use the either. So, I'd just like to know how to find a way to put my RSA key in the format above in order to record it in my smart card. Thanks, Mateus.

Re: Montgomery constants

I'd have to ask you to pardon my ignorance too. In fact I do not know montogomery constants. I'm using cryptoflex smart cards and I'm having problems to find out what are a,c and f that it's Programmer's Guide references. I've found somewhere that this would be some

Montgomery constants

Hi, I'd like to know how to use montgomery references at RSA structure to obtain montgomery constants a,c and f. Thanks in advance. Mateus. __ OpenSSL Project

How can i get Montgomery constants from a RSA key ?

> Is is 'dmq1' ? - Montgomery constant 'J0'  -> Where is it ? - Montgomery constant 'H'   -> Where is it ?   I have no problem to find the first parameters in the RSA structure. But where or how can i find the other parameters, and especially the Montgomery constants ?   Thanks for any help   Stephane Vinsot
