Informations about the package crypto
Crypto Currency for PHP
A collection of common utilities and libraries in PHP for use with Bitcoin and Zetacoin compatable crypto currencies ustilizing the secp256k1 ECDSA curve.
The code may be messy and all over the place, but I'm still pulling things together as I merge this code base with items from the PHPECC codebase. The current features include:

- Public Address Print Out
- Message Signing and Verification
- Address Generation and Validation
- Address compression, de-compression, encoding, and decoding.
- Supports Arbitrary Address Prefixes
Currently, the following items are working
- Base58.php
- SECp256k1.php
- PointMathGMP.php
- AddressValidation.php
- AddressCodec.php
- PrivateKey.php
- Signature.php

Gives you:
Specify your own prefix (in HEX):
