Ok, that makes sense. As far as I can tell, even truncated to "just" 122 bits, there's still no known way to generate a SHA-256 collision, so the MD5/SHA1 versions are comparatively vulnerable vs an hypothetical SHA256 UUID version. However, it's starting to feel like UUIDs may not be long enough in general to meet the need for secure, distributed ID generation. |
