新行附加在我的加密字符串 [英] new line appending on my encrypted string

问题描述

在Main中：

  public static void main（String [] args）throws NoSuchAlgorithmException {
 System.out .println（encrypt：+ encryptPassword（superuser）+：）; 
} 
 
 public static String encryptPassword（final String password）throws NoSuchAlgorithmException {
 MessageDigest md = MessageDigest.getInstance（MD5）; 
 byte [] hashPassword = md.digest（password.getBytes（））; 
 String encryptPass = Base64.encodeBase64String（hashPassword）; 
返回encryptPass; 
} 
  

我得到这个输出：

  encrypt：C66i8K4gFQ23j1jN2sRCqQ ==：
  

但是当我在应用程序中实现同样的事情时，我得到以下输出：

 加密：C66i8K4gFQ23j1jN2sRCqQ == 
：
  

注意：添加我加密字符串的新行。 p>

应用代码：

  public boolean authenticateUsernamePasswordInternal（UsernamePasswordCredentials credentials）{
 try {
 System.out.println（encrypt：+ getHash（superuser）+：）; 
} catch（Exception e）{
 logger.error（e.getMessage（），e）; 
抛出新的BadCredentialsAuthenticationException（ErrorConstants.CONNECTION_FAILED）; 
} 
} 
 
 private String getHash（String password）throws NoSuchAlgorithmException，UnsupportedEncodingException {
 MessageDigest md = MessageDigest.getInstance（MD5）; 
 byte [] hashPassword = md.digest（password.getBytes（））; 
 String encryptPass = Base64.encodeBase64String（hashPassword）; 
返回encryptPass; 
} 
  

我如何删除这个额外的新行。
为什么会发生这种情况，请帮助我原因是什么？

解决方案

可能迟到回答这个问题，但遇到同样的问题。实际问题在这里
Base64.encodeBase64String（hashPassword）

更改该行看起来像这样应该工作：
Base64.encodeBase64String（hashPassword，Base64.NO_WRAP）

默认情况下，Android Base64 util将一个换行符添加到编码字符串的末尾。
Base64.NO_WRAP标志告诉util创建没有换行字符的编码字符串。

检查 here

In Main:

public static void main(String[] args) throws NoSuchAlgorithmException {
    System.out.println("encrypt:" + encryptPassword("superuser")+":" );
}

public static String encryptPassword(final String password) throws NoSuchAlgorithmException {
    MessageDigest md = MessageDigest.getInstance("MD5");
    byte[] hashPassword = md.digest(password.getBytes());
    String encryPass = Base64.encodeBase64String(hashPassword);
    return encryPass;
}

I'm getting this output:

encrypt:C66i8K4gFQ23j1jN2sRCqQ==:

But when I implemented the same thing in my application I'm getting the output below:

encrypt:C66i8K4gFQ23j1jN2sRCqQ==
:

Note: new line appending on my encrypted string.

application code:

public boolean authenticateUsernamePasswordInternal(UsernamePasswordCredentials credentials) {
    try {
        System.out.println("encrypt:" + getHash("superuser")+":" );
    } catch (Exception e) {
        logger.error(e.getMessage(), e);
        throw new BadCredentialsAuthenticationException(ErrorConstants.CONNECTION_FAILED);
    }
}

private String getHash(String password) throws NoSuchAlgorithmException, UnsupportedEncodingException{  
    MessageDigest md = MessageDigest.getInstance("MD5");
    byte[] hashPassword = md.digest(password.getBytes());
    String encryPass = Base64.encodeBase64String(hashPassword);
    return encryPass;
}

How I can remove that extra new line. why this is happened, please help me what is the reason?

解决方案

I may be late in answering this, but came across with same problem. Actually problem lies here Base64.encodeBase64String(hashPassword)

Change that line to look like this it should work: Base64.encodeBase64String(hashPassword,Base64.NO_WRAP)

By default the Android Base64 util adds a newline character to the end of the encoded string. The Base64.NO_WRAP flag tells the util to create the encoded string without the newline character.
