一、可解密加解密算法

1、aes 加解密算法

class AES {private $key;private $iv;public function __construct($key, $iv) {$this->key = $key;$this->iv = $iv;}public function encrypt($data) {$encrypted = openssl_encrypt($data, 'AES-128-ECB', $this->key, OPENSSL_RAW_DATA);return base64_encode($encrypted);}public function decrypt($encryptedData) {$decrypted = openssl_decrypt(base64_decode($encryptedData), 'AES-128-ECB', $this->key, OPENSSL_RAW_DATA);return $decrypted;}public function encryptCBC($data) {$encrypted = openssl_encrypt($data, 'AES-256-CBC', $this->key, OPENSSL_RAW_DATA, $this->iv);return base64_encode($encrypted);}public function decryptCBC($encryptedData) {$decrypted = openssl_decrypt(base64_decode($encryptedData), 'AES-256-CBC', $this->key, OPENSSL_RAW_DATA, $this->iv);return $decrypted;}
}
// 使用示例：
$key = '0123456789abcdef'; // 16字节长度的密钥
$iv = 'fedcba9876543210'; // 16字节长度的初始向量
$aes = new AES($key, $iv);
$data = 'Hello, World!';
$encryptedECB = $aes->encrypt($data);
echo 'AES-128-ECB加密后的数据：' . $encryptedECB . "\n";
$decryptedECB = $aes->decrypt($encryptedECB);
echo 'AES-128-ECB解密后的数据：' . $decryptedECB . "\n";
$encryptedCBC = $aes->encryptCBC($data);
echo 'AES-256-CBC加密后的数据：' . $encryptedCBC . "\n";
$decryptedCBC = $aes->decryptCBC($encryptedCBC);
echo 'AES-256-CBC解密后的数据：' . $decryptedCBC . "\n";

2、旧3des加解密方法

<?php
class Encrypt_3DES
{//加密秘钥，private $_key;private $_iv;public function __construct($key, $iv){$this->_key = $key;$this->_iv = $iv;}/*** 对字符串进行3DES加密* @param string 要加密的字符串* @return mixed 加密成功返回加密后的字符串，否则返回false*/public function encrypt3DES($str){$td = mcrypt_module_open(MCRYPT_3DES, "", MCRYPT_MODE_CBC, "");if ($td === false) {return false;}//检查加密key，iv的长度是否符合算法要求$key = $this->fixLen($this->_key, mcrypt_enc_get_key_size($td));$iv = $this->fixLen($this->_iv, mcrypt_enc_get_iv_size($td));if (mcrypt_generic_init($td, $key, $iv) !== 0) {return false;}$result = mcrypt_generic($td, $str);mcrypt_generic_deinit($td);mcrypt_module_close($td);return base64_encode($result); // 对加密后的结果进行Base64编码}/*** 对加密的字符串进行3DES解密* @param string 要解密的字符串* @return mixed 解密成功返回解密后的字符串，否则返回false*/public function decrypt3DES($str){$td = mcrypt_module_open(MCRYPT_3DES, "", MCRYPT_MODE_CBC, "");if ($td === false) {return false;}//检查加密key，iv的长度是否符合算法要求$key = $this->fixLen($this->_key, mcrypt_enc_get_key_size($td));$iv = $this->fixLen($this->_iv, mcrypt_enc_get_iv_size($td));if (mcrypt_generic_init($td, $key, $iv) !== 0) {return false;}$str = base64_decode($str); // 对加密字符串进行Base64解码$result = mdecrypt_generic($td, $str);mcrypt_generic_deinit($td);mcrypt_module_close($td);return $this->strUnPad($result);}/*** 返回适合算法长度的key，iv字符串* @param string $str key或iv的值* @param int $td_len 符合条件的key或iv长度* @return string 返回处理后的key或iv值*/private function fixLen($str, $td_len){$str_len = strlen($str);if ($str_len > $td_len) {return substr($str, 0, $td_len);} else if ($str_len < $td_len) {return str_pad($str, $td_len, "\0");}return $str;}/*** 返回适合算法的分组大小的字符串长度，末尾使用\0补齐* @param string $str 要加密的字符串* @param int $td_group_len 符合算法的分组长度* @return string 返回处理后字符串*/private function strPad($str, $td_group_len){$padding_len = $td_group_len - (strlen($str) % $td_group_len);return str_pad($str, strlen($str) + $padding_len, "\0");}/*** 返回适合算法的分组大小的字符串长度，去除末尾的\0* @param string $str 要解密的字符串* @return string 返回处理后字符串*/private function strUnPad($str){return rtrim($str, "\0");}
}
$key = '1a2bc@';
$iv = '12345678'; // 将iv改为字符串形式
$str = "abcd123";
$encrypt = new Encrypt_3DES($key, $iv);
$jiaData = $encrypt->encrypt3DES($str);
$jieData = $encrypt->decrypt3DES($jiaData);
echo "未加密字符串：".$str;
echo "\n";
echo "加密字符串：".$jiaData;
echo "\n";
echo "解密密字符串：".$jieData;

 3、新3des加解密方法

<?php
class TripleDes {private $key;private $iv;public function __construct($key, $iv) {$this->key = $key;$this->iv = $iv;}public function encrypt($data) {$encrypted = openssl_encrypt($data, 'des-ede3-cbc', $this->key, OPENSSL_RAW_DATA, $this->iv);return base64_encode($encrypted);}public function decrypt($encryptedData) {$decrypted = openssl_decrypt(base64_decode($encryptedData), 'des-ede3-cbc', $this->key, OPENSSL_RAW_DATA, $this->iv);return $decrypted;}
}
$key = "2312342132"; 
$iv = "12345678"; // 初始化向量长度必须为8位
$des = new TripleDes($key, $iv);
$data = "adsadb123";
echo "要加密的数据:{$data}\n";
$encrypted = $des->encrypt($data);
echo "加密后的数据：" . $encrypted . "\n";
$decrypted = $des->decrypt($encrypted);
echo "解密后的数据：" . $decrypted . "\n";

4、rsa公私钥加解密、签名验签方法

<?php/*** RSA签名类*/
class Rsa
{public $publicKey = '';public $privateKey = '';private $_privKey;/*** * private key*/private $_pubKey;/*** * public key*/private $_keyPath;/*** * the keys saving path*//*** * the construtor,the param $path is the keys saving path* @param string $publicKey  公钥* @param string $privateKey 私钥*/public function __construct($publicKey = null, $privateKey = null){$this->setKey($publicKey, $privateKey);}/*** 设置公钥和私钥* @param string $publicKey  公钥* @param string $privateKey 私钥*/public function setKey($publicKey = null, $privateKey = null){if (!is_null($publicKey)) {$this->publicKey = $publicKey;}if (!is_null($privateKey)) {$this->privateKey = $privateKey;}}/*** * setup the private key*/private function setupPrivKey(){if (is_resource($this->_privKey)) {return true;}$pem = chunk_split($this->privateKey, 64, "\n");$pem = "-----BEGIN PRIVATE KEY-----\n" . $pem .

}
$publicKey = 'MFwwDQYJKoZIhvcNAQEBBQADSwAwSAJBAKZ1mKTymRoGKnHiP1xAy4aiyt5r0BscCZnDAonCrMFZ4kBGriPNHxEaLr5lfBnMKw7k6i+2dsFPSEZooTvqtPUCAwEAAQ==';

5、自定义加密算法1 

function encrypt($data, $key)
{// 将字符串转化为字节数组$data = str_split($data);// 将密钥转化为字节数组$key = str_split($key);// 加密结果$result = '';foreach ($data as $index => $char) {// 获取密钥字符的 ASCII 值$keyChar = ord($key[$index % count($key)]);// 将字符的 ASCII 值与密钥字符的 ASCII 值进行异或运算$encryptedChar = ord($char) ^ $keyChar;// 将加密后的字符拼接到结果字符串中$result .= chr($encryptedChar);}// 将结果字符串转换为 base64 编码$result = base64_encode($result);// 返回加密结果return $result;
}function decrypt($data, $key)
{// 将 base64 编码字符串转换为普通字符串$data = base64_decode($data);// 将字符串转化为字节数组$data = str_split($data);// 将密钥转化为字节数组$key = str_split($key);// 解密结果$result = '';foreach ($data as $index => $char) {// 获取密钥字符的 ASCII 值$keyChar = ord($key[$index % count($key)]);// 将字符的 ASCII 值与密钥字符的 ASCII 值进行异或运算$decryptedChar = ord($char) ^ $keyChar;// 将解密后的字符拼接到结果字符串中$result .= chr($decryptedChar);}// 返回解密结果return $result;
}// 使用示例
$data = "Hello, World!";
$key = "secretKey";
$encryptedData = encrypt($data, $key);
echo "加密后的数据: " . $encryptedData . "\n";
$decryptedData = decrypt($encryptedData, $key);
echo "解密后的数据: " . $decryptedData . "\n";

6、自定义加密算法2

function encrypt($data, $key) {$encryptedData = '';$keyLength = strlen($key);$dataLength = strlen($data);for ($i = 0; $i < $dataLength; $i++) {$encryptedData .= chr(ord($data[$i]) ^ ord($key[$i % $keyLength]));}return base64_encode($encryptedData);
}
function decrypt($data, $key) {$data = base64_decode($data);$decryptedData = '';$keyLength = strlen($key);$dataLength = strlen($data);for ($i = 0; $i < $dataLength; $i++) {$decryptedData .= chr(ord($data[$i]) ^ ord($key[$i % $keyLength]));}return $decryptedData;
}
// 使用示例
$data = 'Hello, World!';
$key = 'secretKey';
$encryptedData = encrypt($data, $key);
echo '加密后的数据: ' . $encryptedData . "\n";
$decryptedData = decrypt($encryptedData, $key);
echo '解密后的数据: ' . $decryptedData . "\n";

7、自定义加密算法3

function encrypt($data, $key) {$encryptedData = '';$keyLength = strlen($key);$dataLength = strlen($data);for ($i = 0; $i < $dataLength; $i++) {$encryptedData .= chr((ord($data[$i]) + ord($key[$i % $keyLength])) % 256);}return bin2hex($encryptedData);
}
function decrypt($data, $key) {$data = hex2bin($data);$decryptedData = '';$keyLength = strlen($key);$dataLength = strlen($data);for ($i = 0; $i < $dataLength; $i++) {$decryptedData .= chr((ord($data[$i]) - ord($key[$i % $keyLength]) + 256) % 256);}return $decryptedData;
}
// 使用示例
$data = 'Hello, World!';
$key = 'secretKey';
$encryptedData = encrypt($data, $key);
echo '加密后的数据: ' . $encryptedData . "\n";
$decryptedData = decrypt($encryptedData, $key);
echo '解密后的数据: ' . $decryptedData . "\n";

二、不可解密加密算法 

1、md5算法 

$pex='pwd';
$pwd='123456';
$pwdMd5=md5($pex.$pwd);
//校验
$pwd=$_POST['pwd'];
$postPwdMd5=md5($pex.$pwd);
if($pwdMd5==$postPwdMd5){echo '密码正确';
}else{echo '密码错误';
}

2、crypt算法

$pex='pwd';
$pwd='123456';
$pwdMd5=crypt($pwd,$pex);
//校验
$pwd=$_POST['pwd'];
$postPwdMd5=crypt($pwd,$pex);
if($pwdMd5==$postPwdMd5){echo '密码正确';
}else{echo '密码错误';
}

3、sha1算法

$pex='pwd';
$pwd='123456';
$pwdMd5=sha1($pwd,$pex);
//校验
$pwd=$_POST['pwd'];
$postPwdMd5=sha1($pwd,$pex);
if($pwdMd5==$postPwdMd5){echo '密码正确';
}else{echo '密码错误';
}

5、hash 算法

$pex='pwd';
$pwd='123456';
$pwdMd5=hash("sha256", $pwd.$pex);
//校验
$pwd=$_POST['pwd'];
$postPwdMd5=hash("sha256", $pwd.$pex);
if($pwdMd5==$postPwdMd5){echo '密码正确';
}else{echo '密码错误';
}

6、 password_hash算法

<?php
$pex='pwd';
$pwd='123456';
$pwdMd5=password_hash($pwd.$pex,PASSWORD_BCRYPT);
//校验
$pwd=$_POST['pwd'];
$postPwdMd5=password_verify($pwd.$pex,$pwdMd5);
if($pwdMd5==$postPwdMd5){echo '密码正确';
}else{echo '密码错误';
}
