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 base32
Base32
This library implements Base32 encoding. In addition to integers it can encode and decode any arbitrary data.
Install
Install with composer.
This branch requires PHP 7.1 or up. The older 1.x branch supports also PHP 5.6 and 7.0.
Usage
This package has both pure PHP and GMP based encoders. By default encoder and decoder will use GMP functions if the extension is installed. If GMP is not available pure PHP encoder will be used instead.
If you are encoding to and from integer use the implicit decodeInteger() and encodeInteger() methods.
Also note that encoding a string and an integer will yield different results.
Encoding Modes
RCF4684
RCF4684 is the default when encoder is created without passing any parameters. Explicit parameters shown below.
RCF4684 HEX
RCF4684 base32hex encoding is identical to previous, except for the character set. This encoding is lexically sortable.
GMP
GMP encoding is identical to previous. Example below is shown with padding disabled.
Crockford's Base32
When decoding, upper and lower case letters are accepted, and i and l will be treated as 1 and o will be treated as 0. When encoding, only upper case letters are used. Hyphens are ignored during decoding.

Character Sets
By default Base32 uses RFC4648 character set. Shortcut is provided for other commonly used character sets. You can also use any custom character set of 32 unique characters.
Speed
Install GMP if you can. It is reasonably faster pure PHP encoder. Below benchmarks are for encoding random_bytes(128) data.
Static Proxy
If you prefer to use static syntax use the provided static proxy.
Testing
You can run tests either manually or automatically on every code change. Automatic tests require entr to work.
