How do I create a new key pair and save them in files? OpenSSL I guess. I have Windows 7 and Xampp, which has OpenSSL in the APache directory (although I am having some problems with openssl_pkey_new() (see Why does openssl_pkey_new() fail?).
Anyway, once I get OpenSSL configured, what does the code look like to create a new key pair and save them in files?
To generate a key pair:
<?php /* Create the private and public key */ $res = openssl_pkey_new(); /* Extract the private key from $res to $privKey */ openssl_pkey_export($res, $privKey); /* Extract the public key from $res to $pubKey */ $pubKey = openssl_pkey_get_details($res); $pubKey = $pubKey["key"]; ?>
To save the key to a target file:
