今天碰到一个很窝火的问题
使用java进行加密

代码如下：

Security.addProvider(new com.sun.crypto.provider.SunJCE());
                        Security.addProvider(new org.bouncycastle.jce.provider.BouncyCastleProvider());// 添加PKCS7Padding支持
                        Cipher cipher = Cipher.getInstance('DESede/ECB/PKCS7Padding', 'BC');
                        Key key = CipherManager.getKey(sig.getBytes('GBK'));
                        cipher.init(Cipher.DECRYPT_MODE, key);
