Finding your Keystore's Signature.; 3 minutes to read; In this article. The MD5 or SHA1 signature of a Xamarin.Android app depends on the.keystore file that was used to sign the APK. Typically, a debug build will use a different.keystore file than a. To answer the original question, on my Mac, keytool is found at /Library/Java/JavaVirtualMachines/jdk1.7.045.jdk/Contents/Home/bin/keytool. You can locate the Java home directory using the /usr/libexec/javahome command line tool on Mac OS X 10.5 or later.
-->The MD5 or SHA1 signature of a Xamarin.Android app depends on the.keystore file that was used to sign the APK. Typically, a debugbuild will use a different .keystore file than a release build.
For Debug / Non-Custom Signed Builds
Xamarin.Android signs all debug builds with the same debug.keystorefile. This file is generated when Xamarin.Android is firstinstalled.The steps below detail the process for finding the MD5 orSHA1 signature of the default Xamarin.Android debug.keystore file.
Locate the Xamarin debug.keystore file that is used to sign theapp. By default, the keystore that is used to sign debug versions ofa Xamarin.Android application can be found at the followinglocation:
C:UsersUSERNAMEAppDataLocalXamarinMono for Androiddebug.keystore
Information about a keystore is obtained by running the keytool.execommand from the JDK. This tool is typically found in the following location:
C:Program Files (x86)JavajdkVERSIONbinkeytool.exe
Add the directory containing keytool.exe to the PATH environment variable.Open a Command Prompt and run keytool.exe using the following command:
When run, keytool.exe should output the following text. The MD5: and SHA1: labels identify the respective signatures:
Locate the Xamarin debug.keystore file that is used to sign theapp. By default, the keystore that is used to sign debug versions ofa Xamarin.Android application can be found at the followinglocation:
~/.local/share/Xamarin/Mono for Android/debug.keystore
Information about a keystore is obtained by running the keytoolcommand from the JDK. This tool is typically found in the followinglocation:
/System/Library/Java/JavaVirtualMachines/VERSION.jdk/Contents/Home/bin/keytool
Add the directory containing keytool to the PATH environment variable.Open a Terminal and run keytoolby using the following command:
When run, keytool should output the following text. The MD5: and SHA1: labels identify the respective signatures:
For Release / Custom Signed Builds
The process for release builds that are signed with a custom.keystore file are the same as above, with the release.keystore file replacing the debug.keystore file that is usedby Xamarin.Android. Replace your own values for the keystore password,and alias name from when the release keystore file was created.
When the Visual Studio Distributewizard is used to sign a Xamarin.Android app, the resulting keystore resides in the following location:
C:UsersUSERNAMEAppDataLocalXamarinMono for AndroidKeystorealiasalias.keystore

For example, if you followed the steps in Create a New Certificate to create a new signing key, the resulting example keystore resides in the following location:
C:UsersUSERNAMEAppDataLocalXamarinMono for AndroidKeystorechimpchimp.keystore

Java Keytool Create Keystore
When the Visual Studio for Mac Sign and Distribute...wizard to sign your app, the resulting keystore resides in the following location:
~/Library/Developer/Xamarin/Keystore/alias/alias.keystore
For example, if you followed the steps in Create a New Certificate to create a new signing key, the resulting example keystore resides in the following location:
~/Library/Developer/Xamarin/Keystore/chimp/chimp.keystore
