What are some best practices for decrypting encrypted text in PHP?
When decrypting encrypted text in PHP, it is important to use a secure encryption algorithm and ensure that the encryption key is kept secret. It is also recommended to use a secure method of storing the encryption key, such as environment variables or a secure key management service.
// Example code for decrypting encrypted text using OpenSSL in PHP
function decryptText($encryptedText, $key) {
$decrypted = openssl_decrypt($encryptedText, 'AES-256-CBC', $key, 0, substr($key, 0, 16));
return $decrypted;
}
// Usage example
$encryptedText = "U2FsdGVkX1+RtV1ZIjBq3v9p8QFf6k9s7VtRZJ9bJ3Y=";
$key = "mysecretkey";
$decryptedText = decryptText($encryptedText, $key);
echo $decryptedText;
