这是一个很晚的答案，但它将帮助像我这样的懒人。将此代码添加到你的Application类中，不需要下载openssl，也不需要设置路径。只需要复制这个代码..和keyHash将在日志中生成。

import com.facebook.FacebookSdk;
public class MyApplication extends Application {

    @Override
    public void onCreate() {
        super.onCreate();
        FacebookSdk.sdkInitialize(getApplicationContext());
        AppEventsLogger.activateApp(this);
        printKeyHash();
    }

    private void printKeyHash() {
        try {
            PackageInfo info = getPackageManager().getPackageInfo(
                    getPackageName(), PackageManager.GET_SIGNATURES);
            for (Signature signature : info.signatures) {
                MessageDigest md = MessageDigest.getInstance("SHA");
                md.update(signature.toByteArray());
                Log.i("KeyHash:",
                        Base64.encodeToString(md.digest(), Base64.DEFAULT));
            }
        } catch (PackageManager.NameNotFoundException e) {
            Log.e("jk", "Exception(NameNotFoundException) : " + e);
        } catch (NoSuchAlgorithmException e) {
            Log.e("mkm", "Exception(NoSuchAlgorithmException) : " + e);
        }
    }
}

不要忘记在manifest中添加MyApplication类:

<application
        android:name=".MyApplication"
</application>

这种方法对我很有效。请更改您的路径

C:\Program Files\Java\jre7\bin keytool -exportcert -alias androiddebugkey -keystore "C:\Users\Ace.android\debug. keystore "keystore" | "C:\openssl\bin

\openssl.exe" sha1 -二进制| "C:\openssl\bin\openssl.exe" base64

在OpenSSL的地方…你必须输入你下载的OpenSSL文件夹的路径。你的实际命令应该是这样的:

keytool -exportcert -alias androiddebugkey -keystore ~/.android/debug.keystore | "C:\Users\abc\openssl\bin\openssl.exe" sha1 -binary | "C:\Users\abc\openssl\bin\openssl.exe" base64

请记住，您将输入的路径将是安装OpenSSL的路径。

编辑:

你可从以下连结下载OpenSSL for windows32及64bit:

OpenSSL for 64位

OpenSSL for 32 Bits

这对我来说很成功。

“C：\Program Files\Java\jdk1.6.0_26\bin\keytool.exe” -exportcert -alias sociallist -keystore “D：\keystore\SocialListing” |“C：\cygwin\bin\openssl.exe” sha1 -binary |“C：\cygwin\bin\openssl.exe” base64

注意以下路径:

“C: \ Program Files \ Java \ jdk1.6.0_26 \ bin \ keytool.exe” “D:\keystore\SocialListing”或者可以是这样的“C:\Users\Shaon.android\debug.keystore” “C:\cygwin\bin\openssl.exe”或者可以像这样:C:\ users \openssl\bin\openssl.exe

如果命令成功工作，那么你将看到这个命令:

输入keystore密码:typeyourpassword

Encryptedhashkey * *

请遵循以下步骤，我希望你的钥匙工作正常:

Step 1 You will need OpenSSL. You can download the binary from openssl-for-windows project on Google Code. Step 2 Unzip the folder, then copy the path to the bin folder to the clipboard. For example, if the file is unzipped to the location C:\Users\gaurav\openssl-0.9.8k_WIN32, then copy the path C:\Users\gaurav\openssl-0.9.8k_WIN32\bin. Step 3 Add the path to your system environment path. After your PATH environment variable is set, open the cmd and type this command: C:\>keytool -exportcert -alias androiddebugkey -keystore [path to debug.keystore] | openssl sha1 -binary | openssl base64 Type your password when prompted. If the command works, then you will be shown a key.
