SunJCE Provider doesn't support RSA for all version of JCE?

Folks,

Have browsed through the forum and it seems that the JCE provider bundled with JCE and JDK1.4+ do nothing on RSA. Can I make this conclusion?

Yes, but: A standard installation of Java comes with 5 providers. SunJCE is only one of these providers. Two other providers, SunJSSE and SunRsaSign do provide RSA for digital signature purposes.

But it seems the SunJCE doesn't provide the RSA (and AES, who knows what else is missing) encryption and decryption functions. Can anyone list what is missing from the SunJCE? Also, from the forum, many have pointed to this bounty castle provider. Can any of you guys who are familiar with this provider give us the procedure of installation? Thanks.

I wouldn't use the term 'missing' here. Sun provides some basic cryptographic functions and that all. If you want more, get another provider. Sun will never be able to provide every possible algorithm. That's why they have implemented the external provider option. So no, I cannot list what is missing.

I can tell you that other providers, for instance BouncyCastle offer much more cryptographic functions. Installation is very easy. Just download the .jar and put it in your <java>\jre\lib\ext directory. After that you can use it in you programs with the following code: 
Provider prov = new org.bouncycastle.jce.provider.BouncyCastleProvider();
Security.addProvider(prov);
You can also install it so that you don't have use this code in every program that uses the provider. How this is accomplished, can be found in the install manual from BouncyCastle.
