私はPHPでRSAを使う方法を見つけようとしています。PHPでRSAを使用する良い例
私は
ssh-keygen -t rsa
で公開鍵と秘密鍵を生成してきましたそして今、私は私のPHPコードからのものを使用しようとしています。終わり

、とアプリのクラッシュ:私が間違っているの何
Cannot get public key
Warning: openssl_public_encrypt() [function.openssl-public-encrypt]: key parameter is not a valid public key in /home/menkaur/public_html/iathao.com/bookmarks/lcn.php on line 13
Cannot Encrypt
ここで私が使用しているコードですか?
