假设您已经在系统中安装了Java，最好是JDK(因为您在问题中提到了它，所以适用于Windows)，您应该在安装的bin文件夹中有keytool实用程序。

如果是这种情况，接下来要做的就是将该bin文件夹添加到Windows安装的PATH环境变量中。

下次你将打开一个Windows shell，你将键入keytool，你将能够运行实际的实用程序。

#进入cacerts或jsk所在路径，打开并在cmd下运行以下命令

Keytool -v -list -keystore cacerts

Keytool -v -list -keystore .jks

keytool是JDK的一部分。

尝试将%{JAVA_HOME}\前置到exec语句或c:\{jdk}的路径\bin。

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。

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

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。
