PHP ile OpenSSL Encrypt ve Decrypt

Sıkça kullandığım bir yöntem.

Özellikle ID’leri şifrelemek için kullanmaktayım.

Basit şekilde kullanımına gelecek olursak :

$sifrelenecek = "muratsever.com"; // Şifrelenecek değer.
$sifrelememetodu = "AES-256-CBC";  // AES şifreleme metodu.Aşağıda tüm metodları bulabilirsiniz.
$benimsifrem = "21c685cf35b9979b151f2136cd13b0f1"; //21c685cf35b9979b151f2136cd13b0f1 yerine kendi belirlediğiniz şifreyi yazın.

//Şifrelenmiş hali
$sifrelenen = openssl_encrypt($sifrelenecek, $sifrelememetodu, $benimsifrem);

//Şifresiz hali
$sifresicozulen = openssl_decrypt($sifrelenen, $sifrelememetodu, $benimsifrem);

//Sonucu yazdırmak için
echo "Şifrelenmiş: $sifrelenen <br>Şifrelenmemiş: $sifresicozulen";

Kodu çalıştırdığımızda şifrelenmiş değer olarak alacağımız çıktı şu şekilde olacak : Cc4GA2rk/1LL7BNAfa1ydw==

Örnekte AES-256-CBC algoritmasını kullandım.Siz aşağıdakilerden herhangi birini seçip kullanabilirsiniz.
