java - 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.
