The constructor<br /><br /><p>If you want to make use of the openssl extension, you'll need to set the mode manually, yourself. The reason Crypt_RSA doesn't do it is because OpenSSL doesn't fail gracefully. openssl_pkey_new(), in particular, requires openssl.cnf be present somewhere and, unfortunately, the only real way to find out is too late.</p><br /><br /><br />

Defines the public key<br /><br /><p>Some private key formats define the public exponent and some don't. Those that don't define it are problematic when used in certain contexts. For example, in SSH-2, RSA authentication works by sending the public key along with a message signed by the private key to the server. The SSH-2 server looks the public key up in an index of public keys and if it's present then proceeds to verify the signature. Problem is, if your private key doesn't include the public exponent this won't work unless you manually add the public exponent.</p><p>Do note that when a new key is loaded the index will be cleared.</p><p>Returns true on success, false on failure</p><br /><br /><br />
