Digg openssl_private_encrypt
Encrypts data with private key
(PHP 4 >= 4.0.6, PHP 5)
openssl_private_encrypt() encrypts data with private key and stores the result into crypted. Encrypted data can be decrypted via openssl_public_decrypt(). This function can be used e.g. to sign data (or its hash) to prove that it is not written by someone else. Code Examples / Notes » openssl_private_encryptwfredknospam
Encrypt using private key, decrypt using public key. Use this for posting signed messages: Anyone with access to your public key can read it, but they can't create one with your signature. <?php echo "Source: $source"; $fp=fopen("/path/to/private.key","r"); $priv_key=fread($fp,8192); fclose($fp); // $passphrase is required if your key is encoded (suggested) $res = openssl_get_privatekey($priv_key,$passphrase); /* * NOTE: Here you use the returned resource value */ openssl_private_encrypt($source,$crypttext,$res); echo "String crypted: $crypttext"; $fp=fopen ("/path/to/certificate.crt","r"); $pub_key=fread($fp,8192); fclose($fp); openssl_get_publickey($pub_key); /* * NOTE: Here you use the $pub_key value (converted, I guess) */ openssl_public_decrypt($crypttext,$newsource,$pub_key); echo "String decrypt : $newsource"; ?> billnet
<?php $fp=fopen ("/path/to/key.pem","r"); $priv_key=fread ($fp,8192); fclose($fp); openssl_get_privatekey ($priv_key); openssl_private_encrypt($source,$finaltext,$priv_key); echo "String crypted: $finaltext"; ?> CIAO ! |
