== How to fix it in Java SE

=== Code examples
The following code uses a cryptographically strong random number generator to generate data that is not cryptographically strong.

==== Noncompliant code example

[source,java,diff-id=1,diff-type=noncompliant]
----
SecureRandom sr = new SecureRandom();
sr.setSeed(123456L); // Noncompliant
int v = sr.next(32);
----

[source,java,diff-id=2,diff-type=noncompliant]
----
SecureRandom sr = new SecureRandom("abcdefghijklmnop".getBytes("us-ascii")); // Noncompliant
int v = sr.next(32);
----

==== Compliant solution

[source,java,diff-id=1,diff-type=compliant]
----
SecureRandom sr = new SecureRandom();
int v = sr.next(32);
----

This solution is available for JDK 1.8 and higher.
[source,java,diff-id=2,diff-type=compliant]
----
SecureRandom sr = SecureRandom.getInstanceStrong();
int v = sr.next(32);
