Re: [Cryptix-users] cryptix with jdk1.5.0_09

[Allan R. <ar...@ex...>]

We had a lot of trouble going to jdk 1.5 because of the order of the
security providers changed, putting a Sun RSA implementation in front of the
Cryptix RSA implementation.

The workaround that worked for us is to insert Cryptix provider in FRONT of
the intruder before getting the cipher instance. Here's how that can be done
in java:

 

            java.security.Security.insertProviderAt(new
cryptix.provider.Cryptix(), 1);

            cipher = xjava.security.Cipher.getInstance("RSA");

 

If you leave the security provider list as is, or insert Cryptix at the end,
you will get an erroneous provider.

 

This assumes dynamic provider addition; I don't have any advice if you must
use static provider addition.

 

Hope this helps.

Subject: [Cryptix-users] cryptix with jdk1.5.0_09

 

Hello,
i just wanted to test an example with cryptix, which i found on :
http://www.ztt.fh-worms.de/de/others/sem/unsorted/cryptix/key_code.html

just only to create an RSA key pair.

I downloaded cryptix version 3.2.0. Then I added the 


provider to java Security, but doesn't work.





Java cannot resole the import like :





import cryptix.security.rsa.*;


import cryptix.security.*;


import cryptix.math.*;





Can anyone please help me? Should i change the codes


for the new cryptix version?





thanks a lot,


Nazli
