php扩展 sodium

<?php
// 生成随机密钥
$encryption_key = sodium_crypto_secretbox_keygen();

// 要加密的数据
$message = "Hello, Sodium!";

// 生成随机的 nonce
$nonce = random_bytes(SODIUM_CRYPTO_SECRETBOX_NONCEBYTES);

// 加密数据
$ciphertext = sodium_crypto_secretbox($message, $nonce, $encryption_key);

// 解密数据
$plaintext = sodium_crypto_secretbox_open($ciphertext, $nonce, $encryption_key);

echo "原始数据: $message\n";
echo "加密数据:$ciphertext";
echo "解密后的数据: $plaintext\n";

$password = "my_secret_password";
$hash = sodium_crypto_generichash($password);

echo "原始密码: $password\n";
echo "Hash: $hash\n";
