如何创建用于Web服务的密码摘要？

我正在尝试创建一个passwordDigest util，它可以在能够运行java字节码的不同环境中使用。

首先我创建nonce。它是这样完成的。

public static String buildNonce(){
        StringBuffer nonce=new StringBuffer();
        String dateTimeString = Long.toString(new Date().getTime());
        byte[] nonceByte= dateTimeString.getBytes();
        return Base64.encode(nonceByte);
    }

一旦我有了nonce，我就构建了密码摘要。

public static String buildPasswordDigest(String userName, String password, String nonce, String dateTime){
    MessageDigest sha1;
    String passwordDigest=null;
    try {
        sha1= MessageDigest.getInstance("SHA-1");
        byte[] hash = MessageDigest.getInstance("SHA-1").digest(password.getBytes("UTF-8"));
        sha1.update(nonce.getBytes("UTF-8"));
        sha1.update(dateTime.getBytes("UTF-8"));
        passwordDigest = new String(Base64.encode(sha1.digest(hash)));
        sha1.reset();
    } catch (NoSuchAlgorithmException | UnsupportedEncodingException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
    return passwordDigest;

为了测试一切正常。我使用CXF 2.7创建了一个测试Web服务。我手动创建了SOAP Envelope来测试身份验证。信封看起来像这样。

 <soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" 
                xmlns:ws="http://ws.mytest.org/" 
                xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance/">
    <soapenv:Header>
        <wsse:Security soapenv:mustUnderstand="1" 
          xmlns:wsse="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd" 
          xmlns:wsu="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd">
          <wsse:UsernameToken wsu:Id="UsernameToken-2">
            <wsse:Username>TEST_USER</wsse:Username>
            <wsse:Password 
            Type="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-username-token-profile-1.0#PasswordDigest">UZsDSW/vANu6fHg4rAHo2OwsF9s=</wsse:Password
            <wsse:Nonce>MTQwMTMwMDQzNjA3OA==</wsse:Nonce>
            <wsu:Created>2014-05-28T18:07:16.087Z</wsu:Created>
         </wsse:UsernameToken>
        </wsse:Security>
    </soapenv:Header>
    <soapenv:Body>
        <ws:record>
            <val1>1</val1>
            <val2>Some Text</val2>
        </ws:record>
    </soapenv:Body>
</soapenv:Envelope>

当我使用SOAP UI发送信封时。我收到以下身份验证错误。

我怀疑我在创建nonce或密码时遇到问题。

感谢您的帮助。

答案 0 :(得分：6)

WS-Security将密码摘要定义为

  

Base64（SHA1（nonce + created +密码））

不是

  

Base64（SHA1（密码+随机数+已创建））

nonce应该是128位（16字节）编码为Base64。 e.g。

java.security.SecureRandom random = java.security.SecureRandom.getInstance("SHA1PRNG");
random.setSeed(System.currentTimeMillis()); 
byte[] nonceBytes = new byte[16]; 
random.nextBytes(nonceBytes); 
String nonce = new String(org.apache.commons.codec.binary.Base64.encodeBase64(nonceBytes), "UTF-8");

答案 1 :(得分：0)

应该按照下面的代码片段那样构造随机数和密码摘要。

请注意元素的顺序，以及nonce的未编码版本用于passwordDigest构造的事实。

import javax.xml.datatype.*;
import java.security.*;
import java.time.Instant;
import java.util.Base64;

import static java.lang.System.currentTimeMillis;
import static java.nio.charset.StandardCharsets.UTF_8;

class Snippet {

    private static final SecureRandom RANDOM;
    private static final int NONCE_SIZE_IN_BYTES = 16;
    private static final String MESSAGE_DIGEST_ALGORITHM_NAME_SHA_1 = "SHA-1";
    private static final String SECURE_RANDOM_ALGORITHM_SHA_1_PRNG = "SHA1PRNG";

    static {
        try {
            RANDOM = SecureRandom.getInstance(SECURE_RANDOM_ALGORITHM_SHA_1_PRNG);
            RANDOM.setSeed(currentTimeMillis());
        } catch (NoSuchAlgorithmException e) {
            throw new RuntimeException(e);
        }
    }

    public static void main(String[] args) throws DatatypeConfigurationException {
        final var nonceBytes = generateNonce();

        final var password = "password";
        final var createdDate = DatatypeFactory.newInstance().newXMLGregorianCalendar(Instant.now().toString());
        final var passwordDigestBytes = constructPasswordDigest(nonceBytes, createdDate, password);

        final var base64Encoder = Base64.getEncoder();
        final var nonceBase64Encoded = base64Encoder.encodeToString(nonceBytes);
        final var passwordDigestBase64Encoded = base64Encoder.encodeToString(passwordDigestBytes);
        System.out.println(String.format("nonce: [%s], password digest: [%s]", nonceBase64Encoded, passwordDigestBase64Encoded));
        System.out.flush();
    }

    private static byte[] generateNonce() {
        var nonceBytes = new byte[NONCE_SIZE_IN_BYTES];
        RANDOM.nextBytes(nonceBytes);
        return nonceBytes;
    }

    /**
     * @noinspection SameParameterValue
     */
    private static byte[] constructPasswordDigest(byte[] nonceBytes, XMLGregorianCalendar createdDate, String password) {
        try {
            final var sha1MessageDigest = MessageDigest.getInstance(MESSAGE_DIGEST_ALGORITHM_NAME_SHA_1);
            sha1MessageDigest.update(nonceBytes);
            final var createdDateAsString = createdDate.toString();
            sha1MessageDigest.update(createdDateAsString.getBytes(UTF_8));
            sha1MessageDigest.update(password.getBytes(UTF_8));
            return sha1MessageDigest.digest();
        } catch (NoSuchAlgorithmException e) {
            throw new RuntimeException(e);
        }
    }
}

此代码段的输出为：
