Fred Dushin resolved WSS-88.
----------------------------
Resolution: Fixed
> SecureRandom.getInstance("SHA1PRNG") is slow on IBM JDK 1.4.2 (And perhaps
> others)
> ----------------------------------------------------------------------------------
>
> 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
> Attachments: patch.diff
>
>
> 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
