Is it safe to use Python UUID module generated values in URL's of a webpage? Wnat to use those ID's as part of URL's. Are there any non-safe characters ever generated by Python UUID that shouldn't be in URL's?

I want to use PostgreSQL's native UUID type with a Java UUID. I am using Hibernate as my JPA provider and ORM. If I try to save it directly, it is just saved as a bytea in Postgres.
How can I do this?

Check this,
List<String> list = new ArrayList<String>(); for (int i = 0; i < 10000; i++) { String value = (""+UUID.randomUUID().getLeastSignificantBits()).substring(3, 20); assertFalse(list.contains(value)); assertTrue(value.length() <...
