Question 1

How to generate a short UUID in Python with shortuuid?

Accepted Answer

Import the library using 'import shortuuid' and call 'shortuuid.uuid()' to generate a short UUID. For cryptographic security, use 'shortuuid.ShortUUID().random(length=22)' with os.urandom(). The default output is a 22-character string.

Question 2

Shortuuid or standard UUID: which is better for my project?

Accepted Answer

Choose shortuuid for user-facing contexts like URLs or API keys where compact, readable IDs are needed. Standard UUIDs are better for universal uniqueness without encoding overhead, but they are longer and less user-friendly.

Question 3

Can I use shortuuid with Django models easily?

Accepted Answer

Yes, shortuuid provides a ShortUUIDField that integrates directly into Django models. Import it from 'shortuuid.django_fields' and define it with options like length and alphabet for seamless database usage.

Question 4

Is shortuuid cryptographically secure for random strings?

Accepted Answer

For random string generation, shortuuid uses 'os.urandom()', which is cryptographically secure. However, the standard UUID generation depends on Python's uuid module, so check version-specific security if needed.

Question 5

How to customize the alphabet in shortuuid for specific needs?

Accepted Answer

Use 'shortuuid.set_alphabet("your_alphabet")' to define a custom alphabet. The library automatically sorts and removes duplicates unless 'dont_sort_alphabet=True' is set for compatibility with other implementations.

Question 6

What happens if I truncate a shortuuid ID to make it shorter?

Accepted Answer

Truncating reduces the ID length and increases collision probability, as noted in the README. While still low for many use cases, it's not recommended for systems where uniqueness must be guaranteed without risk.
