分享求php 3des 加解密 兼容 java
现有java 版3des加解密程序，求php版3des加解密程序，网上找了一些均不合适。
/**
* 3des加密
*
* @param key 密钥
* @param data 明文数据 16进制且长度为16的整数倍不足时补0
* @return 密文数据
*/
public static byte[] Union3DesEncrypt(byte[] key, byte[] data) {
try {
byte[] k = new byte[24];
if (key.length == 16) {
System.arraycopy(key, 0, k, 0, key.length);
System.arraycopy(key, 0, k, 16, 8);
} else {
System.arraycopy(key, 0, k, 0, 24);
}
byte[] buff = EncodeUtils.complementZero(data);
KeySpec ks = new DESedeKeySpec(k);
SecretKeyFactory kf = SecretKeyFactory.getInstance("DESede");
SecretKey ky = kf.generateSecret(ks);
Cipher c = Cipher.getInstance("DESede/ECB/NoPadding");
c.init(Cipher.ENCRYPT_MODE, ky);
return c.doFinal(buff);
} catch (Exception e) {
e.printStackTrace();
return null;
}
}

为什么我使用这个加密后与java不一致，而且刷新后，每次都不一样
