Re: oracle 10g cryptography problem

Dear Vladimir ,

Unfortunately sunjce only supports RSA in jdk 1.5+ and for jdk 1.4 (used by oracle 10.2.0.1) a third party provider is needed. I have followed the metalink instructions with no luck and 10.2.0.2 is not available for 32-bit windows! Its quite the dilemma...
