Ext/OpenSSL patch

Hi, I propose a patch for ext/openssl that extends support for crypto API. - it provides access to openSSL digest functions function openssl_get_md_methods(); function openssl_digest(string $data, string $method [, bool $raw]); - it provides access to openSSL digest functions function openssl_get_cipher_methods(); function openssl_encrypt(string $data, string $method, $string $password [, bool $raw]); function openssl_decrypt(string $data, string $method, $string $password [, bool $raw]); - It extends existing functions openssl_pkey_new() and openssl_pkey_get_details() to access internal values of DSA, RSA and DH keys. For example you can create DH key and then access its internal values using the following code: <?php $dh = openssl_pkey_new(array('dh' => array( 'p' => pack('H*', 'dcf93a0b883972ec'), 'g' => pack(H*', '02'))); $details = openssl_pkey_get_details($dh); var_dump(base64_encode($deteils['dh']['p'])); var_dump(base64_encode($deteils['dh']['g'])); var_dump(base64_encode($deteils['dh']['priv_key'])); var_dump(base64_encode($deteils['dh']['pub_key'])); ?> - it provides new function that computes shared secret for two DH keys function openssl_dh_compute_key(string $pub_key, resource $dh) - it also extend some functions to support string name of crypto algorith in addition to numeric constants. This patch was written to implement OpenID protocol in PHP. It is similar to patch by Wez http://netevil.org/blog/2007/feb/openid-and-typekey-using-native-openssl-fun ctions-in-php but it provides less additional functions and works with big numbers as with strings (instead of resources). I would like to commit the path to PHP_5_2 and HEAD. Any objections? Thanks. Dmitry.
