在PHP中使用OpenSSL加密和解密数据可以通过以下步骤实现:
- 加密数据:
$data = 'https://www.yisu.com/ask/Hello World'; $key = 'secret_key'; $method = 'AES-256-CBC'; $iv = openssl_random_pseudo_bytes(openssl_cipher_iv_length($method)); $encrypted = openssl_encrypt($data, $method, $key, 0, $iv); // Store the encrypted data and IV for later decryption $encryptedData = https://www.yisu.com/ask/base64_encode($encrypted);>
- 解密数据:
$encrypted = base64_decode($encryptedData); $iv = base64_decode($ivData); $decrypted = openssl_decrypt($encrypted, $method, $key, 0, $iv); echo $decrypted; // Output: Hello World请注意,确保在加密和解密数据时使用相同的加密算法、密钥和初始化向量(IV)。此外,建议在存储和传输加密数据时进行base64编码以确保数据的完整性。
