scalajs-fake-insecure-java-securerandom provides compatibility stubs for java.security.SecureRandom in Scala.js.

This library is insecure by design. It does not provide a cryptographically secure implementation of SecureRandom. It is only there to preserve support for java.util.UUID.randomUUID() from Scala.js core previous to v1.10.0 in environments where secure UUID generation is not a requirement, and if there is no other choice.

Use scalajs-java-securerandom instead.

Never, ever depend on scalajs-fake-insecure-securerandom from library code!

If you do, you will expose your users to insecure code.

Always use scalajs-java-securerandom instead.

Almost never depend on scalajs-fake-insecure-securerandom. Use scalajs-java-securerandom instead if possible, notably if you only target browsers and/or Node.js.

If you have no other choice, use the following dependency:

libraryDependencies += ("org.scala-js" %%% "scalajs-fake-insecure-java-securerandom" % "1.0.0").cross(CrossVersion.for3Use2_13)

When using a crossProject, add the above in .jsSettings(...).

You can then use java.security.SecureRandom from your code, and by extension, the java.util.UUID.randomUUID() method. Keep in mind that the generated random numbers (and random UUIDs) will not be cryptographically secure.
