Subject: NoSuchAlgorithmException: SHA1PRNG SecureRandom - on Websphere 5.2.1 - J2EE 1.3
Hello,
This exception occure when I try to call a
webservice with wss4j:
[23/05/05 11:43:17:505 CEST] 729a159b
SystemErr R
java.security.NoSuchAlgorithmException:

In fact, SHA1PRNG is not
implemented in IBM JRE. The only solution I've got
to make it work is to
change wss4j sources ConvertionUtil.java and
UsernameToken.java like
this:
SecureRandom random =
null;
try
{
random =
SecureRandom.getInstance("SHA1PRNG");
} catch (NoSuchAlgorithmException e)
{
try
{
System.out.println("calling SecureRandom.getInstance
with
IBMSecureRandom");
random =
SecureRandom.getInstance("IBMSecureRandom");
} catch (NoSuchAlgorithmException nsa1)
{
System.out.println(nsa1);
}
}
Do you know another way
more elegant to do this without changing my
jvm?
Thanks,
Benjamin
