new line appending on my encrypted string

Question

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?

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.
