只需在Windows命令提示符中输入这些。

cd C:\Program Files\Java\jdk1.7.0_09\bin

keytool -exportcert -alias androiddebugkey -keystore "C:\Users\userName\.android\debug.keystore" -list -v

基本密码为android

您将看到MD5、SHA1和SHA256密钥;选择一个你需要的。

Android:在Android中执行keytool命令的位置

如果在classpath变量中设置了JRE，则可以在dos命令提示符下运行Keytool命令。

例如，如果您想获取android SDK调试证书的MD5指纹，

只需运行以下命令…

C:\Documents and Settings\user\.android>  keytool -list -alias androiddebugkey -keystore debug.keystore -storepass android -keypass android

C:\Documents and Settings\user\.Android >是包含调试的路径。必须经过认证的密钥存储库。

我自己找到了一个解决方案，如下所示。它工作得很好。

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

Few observations while I was getting the same problem (Windows). 1. Shell pipe is important. 2. If you are using OpenSSL or Cygwin, definitely you have to install it. 3. keytool comes with JDK so either you have to point to it in the command or you have cd to the JDK/bin folder (where the exe resides) 4. The debug keystore is typically located at ~/.android/debug.keystore 5. password is "android" whether you -keypass it or type it when prompted. 6. For the alias name, you can open (DO NOT SAVE, just open and close) the keystore file with any editor and read it. 7. MOST IMPORTANT - There is a difference is specifying the keystore path within quotes and without. I got it working by using the keystore path within the double quotes. As remix090378 said and as per the instruction, this command indeed worked - cd C:\Program Files\Java\jdk1.7.0_09\bin

keytool -exportcert -alias androiddebugkey -keystore "C:\Users\userName.android\debug. keystore "密钥存储库" -list -v

Robby Pond的回答可以概括为使用JAVA_HOME环境变量，并补偿路径中可能出现的任何空白(如Program Files):

"%JAVA_HOME%\bin\keytool" -exportcert -alias androiddebugkey -keystore ~/.android/debug.keystore | openssl sha1 -binary | openssl base64

JDK自带keytool。如果您正在使用cygwin，那么这可能已经在您的路径上了。否则，您可能会在JDK的bin文件夹中查找。

为了使shell管道(|)正常工作，您可能需要使用cygwin。
