Crypt_RSA

Provides RSA-like key generation, encryption/decryption, signing and signature checking

This package allows you to use two-key strong cryptography like RSA with arbitrary key length. It uses one of the following extensions for math calculations: - PECL big_int extension ( http://pecl.php.net/packages/big_int ) version greater than or equal to 1.0.3 - PHP GMP extension ( http://php.net/gmp ) - PHP BCMath extension ( http://php.net/manual/en/ref.bc.php ) for both PHP4 and PHP5 valyala Alexander Valyalkin valyala@gmail.com lead 1.2.0b 2006-02-26 PHP beta * added toPEMString() function in Crypt_RSA_KeyPair class. It allows to store keypair in .pem file as RSA private key * added isEqual() function in Crypt_RSA_KeyPair class. It returns true if two keypairs are equal * added mod() and isPrime() functions to math wrappers interface * fixed bug in getPrime() function of GMP and BCMath math wrappers, which hangs up key generating process * added optional $random_generator parameter to Crypt_RSA_KeyPair constructor and factory() method * added benchmark in tests/bench.php, which clearly shows performance of different math wrappers (GMP, BigInt, BCMath). In short: GMP is 5 times faster than BigInt, BCMath is 50 times slower than BigInt. bcmath gmp big_int
