Question 1

How to set up Optimus in Laravel?

Accepted Answer

Create a service provider to register a singleton Optimus instance with your prime numbers, then add it to config/app.php, as detailed in the README's Laravel integration section. This ensures dependency injection across controllers for easy encoding and decoding.

Question 2

Optimus vs Hashids: which is better for my project?

Accepted Answer

Optimus is better if you need fast, integer-based hashes for URLs or APIs, while Hashids is preferable for string outputs or simpler setup. Optimus offers reversibility and performance but requires more initial configuration with prime numbers.

Question 3

Can Optimus handle negative IDs or zero?

Accepted Answer

No, the library focuses on positive integers, as it uses multiplicative hashing with primes, which may not support negative values or zero without modifications. Check the README for constraints on input ranges.

Question 4

Is Optimus secure enough for public APIs?

Accepted Answer

It provides obfuscation, not encryption, so it hides sequential patterns but shouldn't be used for sensitive data. The reversible nature means encoded IDs can be decoded if the prime numbers are known, limiting security for high-risk scenarios.

Question 5

How to generate the prime numbers for Optimus?

Accepted Answer

Use the included console command 'php vendor/bin/optimus spark' to auto-generate primes, inverses, and random numbers, or provide your own prime from a list. The README explains this with examples for customization.

Question 6

What happens if I lose the prime or inverse numbers?

Accepted Answer

You'll be unable to decode previously encoded IDs, as they are essential for the reversible hashing. The README warns to use the same values throughout your application, so store them securely in configuration.
