Functions for calculations with arbitrary length integers and bitsets
Functions from this package are useful for number theory applications. For example, in two-keys cryptography.
See /tests/RSA.php in the package for example of simple implementation of RSA-like cryptoalgorithm. See http//chat.finalcombat.com/vayala/big_int/ page for more complex implementation of RSA-like crypto, which supports key generating, encrypting/decrypting, signing and validating of sign.
The package has many bitset functions, which allow to work with arbitrary length bitsets.
This package is much faster than bundled into PHP BCMath and consists almost all functions, which are implemented in PHP GMP extension, but it needn’t any external libraries.
