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

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 * *

下载和解压缩

你可以从以下连结下载openssl for windows32及64bit:

https://code.google.com/archive/p/openssl-for-windows/downloads

OpenSSL for 64 Bits OpenSSL for 32 Bits

keytool -exportcert -alias androiddebugkey -keystore %HOMEPATH%\.android\debug.keystore | **"C:\Users\keshav.gera\openssl-0.9.8k_X64\bin**\openssl.exe" sha1 -binary | **"C:\Users\keshav.gera\openssl-0.9.8k_X64\bin**\openssl.exe" base64

重要的改变我们的路径这里以及安装开放ssl在您的系统

毫无疑问，这是有效的

C:\Users\keshav.gera>keytool -exportcert -alias androiddebugkey -keystore %HOMEPATH%\.android\debug.keystore | "C:\Users\keshav.gera\openssl-0.9.8k_X64\bin\openssl.exe" sha1 -binary | "C:\Users\keshav.gera\openssl-0.9.8k_X64\bin\openssl.exe" base64

输入keystore密码:android

**ZrRtxw36xWNYL+h3aJdcCeQQxi0=**

=============================================================

通过编码手动使用

import android.content.pm.PackageInfo;
import android.content.pm.PackageManager;
import android.content.pm.Signature;
import java.security.MessageDigest;
import java.security.NoSuchAlgorithmException;


private void PrintHashKey() {

        try {
            PackageInfo info = getPackageManager().getPackageInfo("**com.keshav.patanjalidemo  Your Package Name Here**", PackageManager.GET_SIGNATURES);
            for (Signature signature : info.signatures) {
                MessageDigest md = MessageDigest.getInstance("SHA");        
                md.update(signature.toByteArray());
                Log.d("KeyHash:", Base64.encodeToString(md.digest(), Base64.DEFAULT));
            }
        } catch (PackageManager.NameNotFoundException e) {
            e.printStackTrace();
        } catch (NoSuchAlgorithmException e) {
            e.printStackTrace();
        }

    }

使用整个路径，像这样:

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

这对我很管用。

不能保证用这个单独的openssl方法生成hashkey就能正常工作。 如果对我没用的话。但是谢谢你给了我解决问题的方向。

保证解决方案: 您需要将整个命令分解为单独的命令，并且必须将每次执行的输出写入文件。

享受:)

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.
