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...

Pouria

As of the OP's issue, note 369369.1 on MetaLink describes steps to add
and load third-party providers to the Oracle VM. Also, the note states
that there was a bug in 10.2.0.1 (bug #4475814) that prevented third-
party providers from working inside the Oracle VM, which is fixed in
10.2.0.2. In 10.2.0.1, only SunJce is supported. However, since SunJce
supports RSA, I don't see an urgent need to load Bouncy Castle and go
through the bouncing hassle of applying the patchset and then
following the note 369369.1 to make it work... :)

i understand the message, what i don't understand is why it can't find
an RSA provider when i'm purposely supplying it with one (bouncy
castle).

secondly i need to use an asymmetric cryptographic algorithm:
Obfuscation toolkit and DBMS_CRYPTO do not support these to the best
of my knowledge (please correct me if i'm wrong).

Which part of the message don't you understand?

And no version of Oracle named.

Put away the RSA and use the built-in tools. Obfuscation toolkit if
9i and DBMS_CRYPTO if 10g.

I may be incorrect on this but I believe AES is asymmetric.

AES is symmetric.
