Android-Facebook应用程序的键散列

我正在开发一个Android应用程序，我想在其中集成一个Facebook 发布功能。我下载了Facebook-Android SDK，然后 readme。Md(文本文件)在那里，其中提到要生成 Android的键散列。我如何生成它?

其他回答

试试这个:

两种方法来获得哈希键值

1)从命令行获取哈希键(官方文档:https://developers.facebook.com/docs/android/getting-started)

keytool -exportcert -alias androiddebugkey -keystore %HOMEPATH%\.android\debug.keystore | openssl sha1 -binary | openssl
base64

OR

2)获取哈希键使用代码

  @Override
   protected void onCreate(Bundle savedInstanceState) {
           super.onCreate(savedInstanceState);
           setContentView(R.layout.activity_main);

            //Hask Kay generation 
             GetKeyHase();
    }

    private void GetKeyHase() {
            try {
                PackageInfo info = getPackageManager().getPackageInfo("ADD YOUR PACKAGE NAME", PackageManager.GET_SIGNATURES);
                for (Signature signature : info.signatures) {
                    MessageDigest md = (MessageDigest.getInstance("SHA"));
                    md.update(signature.toByteArray());
                    String hashkey_value = new String(Base64.encode(md.digest(), 0));
                    Log.e("hash key", hashkey_value);
                    //check you logcat hash key value
                }
            }catch (Exception e) {
                Log.e("exception", e.toString());
            }
        }

[EDIT 2020]->现在我完全推荐这里的答案，使用android studio更容易，更快，不需要写任何代码-下面这个是在eclipse时代的:)-。

您可以在任何活动中使用此代码。它将在logcat中记录hashkey，这是调试键。这很简单，而且比使用SSL轻松。

PackageInfo info;
try {
    info = getPackageManager().getPackageInfo("com.you.name", PackageManager.GET_SIGNATURES);
    for (Signature signature : info.signatures) {
        MessageDigest md;
        md = MessageDigest.getInstance("SHA");
        md.update(signature.toByteArray());
        String something = new String(Base64.encode(md.digest(), 0));
        //String something = new String(Base64.encodeBytes(md.digest()));
        Log.e("hash key", something);
    }
} catch (NameNotFoundException e1) {
    Log.e("name not found", e1.toString());
} catch (NoSuchAlgorithmException e) {
    Log.e("no such an algorithm", e.toString());
} catch (Exception e) {
    Log.e("exception", e.toString());
}

你可以在知道密钥后删除代码;)

要生成释放密钥的散列，请在Mac或Windows上运行以下命令，替换释放密钥别名和密钥存储库的路径。

在Windows上，使用:

keytool -exportcert -alias <RELEASE_KEY_ALIAS> -keystore <RELEASE_KEY_PATH> | openssl sha1 -binary | openssl base64

这个命令应该生成一个28个字符的字符串。记住，复制并粘贴这个释放键哈希到你的Facebook应用ID的Android设置。

对于Android应用程序

这段代码用于在Android应用程序中获取Facebook集成的哈希键。我已经测试了所有的设备，一切正常。只更改此代码的包名:

private void facebookHashKey() {

    try {
        PackageInfo info = getPackageManager().getPackageInfo("com.app.helpcove", PackageManager.GET_SIGNATURES);
        for (Signature signature : info.signatures) {
            MessageDigest md = MessageDigest.getInstance("SHA");
            md.update(signature.toByteArray());
            String hashCode  = Base64.encodeToString(md.digest(), Base64.DEFAULT);
            System.out.println("Print the hashKey for Facebook :"+hashCode);
            Log.d("KeyHash:", Base64.encodeToString(md.digest(), Base64.DEFAULT));
        }
    } catch (NameNotFoundException e) {

    } catch (NoSuchAlgorithmException e) {

    }
}
