Support by Bouncy Castle

Have you ever met this Exception like "Cryptography - JCE cannot authenticate provider BC"? and by now you don't know how to deal with it?  If you all say "yes",  Congratulations! Your have came the  right place.

 

Follow me, i will give you the answer and tell you why should do like this.

 

Solution

 

1. DownLoad BC

You can download this lib form www.bouncycastle.org,  type and version should choose by your current case, here i will choose java and which lastest java releases -- bcprov-jdk16-143.jar.

 

2. Deploy BC to JRE/JDK

Copy this lib to your JRE/JDK base lib directory, for example

as to me, which like:

 

XP:

C:\Program Files\Java\jre1.6.0_07\lib\ext

 

Debin:

/usr/local/jre1.6.0_14/lib/ext

 

If you need, you can deploy them to JDK's dir, just as you wish.

 

3.Set JCE Security Provider

Open "java.security" and set the BC provider.

Directory like:

 

XP:

C:\Program Files\Java\jre1.6.0_07\lib\security

 

Debin:

/usr/local/jre1.6.0_14/lib/security

 

And add the BC provider

security.provider.2=org.bouncycastle.jce.provider.BouncyCastleProvider

 

Now, That all of BC part.

 

Addition

As to Java, if you want to use Long key, now you should get the support be JCE,  version should fit to your JDK/JRE. More see my another aritcle "Chapter One：Install EJBCA "
