FAQ
Example:
In general, it is recommended to use always a project to download your libraries. In an application normally there is more than one library needed.
- Some hosting areas are not accessible by a terminal or SSH. Then it is not possible to use Composer.
- To use Composer is sometimes complicated. Especially for beginners.
- Composer needs much resources. Sometimes they are not available on a simple webspace.
- If you are using private repositories you don't need to share your credentials. You can set up everything on our site and then you provide a simple download link to your team member.
- Simplify your Composer build process. Use our own command line tool to download the vendor folder as binary. This makes your build process faster and you don't need to expose your credentials for private repositories.
Informations about the package permuteseq
A small PHP library to obfuscate numbers. Use it when you don't want to expose your database numeric ids to users.
The permutations are collision-free and fully deterministic. The random-looking effect is due to encryption, not to a PRNG. The same boundary range with the same secret key will always produce the same output.
Installation
You can install the package via composer:
Usage
Testing
In order to ensure compability with the Postgres extension, an integration test is included:

Alternatives

-
https://github.com/vinkla/hashids \ Generates YouTube-like ids from numbers. Can be limited to digit-alphabet, but returns strings like
"09284"instead of safe integers. - https://github.com/jenssegers/optimus \ Super-fast number obfuscation based on Knuth's integer hash. However, range can only be defined by 4-62 bits.
