在JAVA中快速简单的字符串加密/解密
我需要一种快速简单的方法来 数据的“很多” 。我尝试了 但在我的
手机上崩溃了。我大约有 (字符串)。
BasicTextEncryptor textEncryptor = new BasicTextEncryptor();textEncryptor.setPassword("password");
String myEncryptedText = textEncryptor.encrypt(input);
还有其他方法吗?我不需要极高的安全性,它需要 !

Java-从配置文件加密/解密用户名和密码
链接上方的代码
DESKeySpec keySpec = new DESKeySpec("Your secret Key phrase".getBytes("UTF8"));SecretKeyFactory keyFactory = SecretKeyFactory.getInstance("DES");
SecretKey key = keyFactory.generateSecret(keySpec);
sun.misc.BASE64Encoder base64encoder = new BASE64Encoder();
sun.misc.BASE64Decoder base64decoder = new BASE64Decoder();
.........
// ENCODE plainTextPassword String
byte[] cleartext = plainTextPassword.getBytes("UTF8");
Cipher cipher = Cipher.getInstance("DES"); // cipher is not thread safe
cipher.init(Cipher.ENCRYPT_MODE, key);
String encryptedPwd = base64encoder.encode(cipher.doFinal(cleartext));
// now you can store it
......
// DECODE encryptedPwd String
byte[] encrypedPwdBytes = base64decoder.decodeBuffer(encryptedPwd);
Cipher cipher = Cipher.getInstance("DES");// cipher is not thread safe
cipher.init(Cipher.DECRYPT_MODE, key);
byte[] plainTextPwdBytes = (cipher.doFinal(encrypedPwdBytes));
