>                 Key: WSS-88
>                 URL: https://issues.apache.org/jira/browse/WSS-88
>             Project: WSS4J
>          Issue Type: Improvement
>         Environment: Windows/ Solaris IBM JDK 1.4.2
>            Reporter: Rasmus Rhein Helwigh
>            Assignee: Fred Dushin

> The methods 
> org.apache.ws.security.message.WSSecEncryptedKey.generateEphemeralKey
> org.apache.ws.security.message.token ( static )
> org.apache.ws.security.util.generateNonce
> all use  the method
> java.security.SecureRandom.getInstance("SHA1PRNG") 
> generating random numbers with this instance is very slow on the IBM JDK ( Generating 32 random bytes takes about 2 seconds, where it it takes less that 1ms on SUN's jdk ).
> Would it be possible to use another random algorithm that performs better?
> The IBM JDK method SecureRandom.getInstance("IBMSecureRandom"); performs as good as the one in the sun API.
> ----- Notes ----
> The reason I'm filing this improvement is because I'm using rampart to request a Secure Token from a Tokenservice. Because of the above mentioned problem, issuing a token takes 7.4 secons on a 2.4 ghz windows machine using IBM jdk 1.4.2. On Suns JDK it takes 200ms. 
> As a result, I'm forced to use a custom build version of the WSS4J, but I'd really prefer to use the std API.
> I know this could be seen as an error in the IBM jdk, but I'd prefer if I could get the improvement done in the WSS4J API.
> Regards Rasmus Helwigh, Safewhere
