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 bip39
PHP BIP39
An easy to use, multilingual, stand alone, and blockchain independent implementation of the **BIP39 proposal for PHP.
This library allows encoding and decoding data, on the 128-256 bit range into Mnemonic word lists.
Have you ever used a local Bitcoin wallet? remember those 12 words you type to backup your private key? This library allows that functionality on PHP.
1. Background.
This library was built with both, production usage readiness and conceptual learning in mind.
It means all code is over commented with detailed information about each single aspect of encoding and decoding BIP39 word sequences.
2. Install:
Standard composer installation:
3. Concepts:
While implementing this library in your projects, you will need to understand some key factors:
3.1. Entropy:
On this library implementation, we call entropy a given set of data, which bits are within the 128 bit to 256 bit.
This means, for example, that you may generate a 256 bit private key for ECDSA, and allow your users to encode this random, hard to remember key into a set of words.
Ways for obtaining entropy:
If you already have a value you want to encode:
or, if you want to generate some data to then create a private key, one could:
3.2. Encoding and Decoding.
Just as simple as using the entropy, parsing from entropy into a word sequence and vice versa is really easy:
And, just as easy as encoding:
Easy right?
3.3. Supported Languages:
- [en] English
- [es] Spanish
- [fr] French
- [it] Italian
- [ja] Japanese
- [ko] Korean
- [zh] Chinese (Simplified).
Just use the language locale on the Bip39 constructor:
3.4. Special Features.
As mentioned earlier, this library was built with education also in mind, so, there's a buffered binary operations class, classed BitBuffer and some utils that will help you understand a lot of different concepts.
Good Leaning!
