Generating the SHA1 fingerprint

Let's learn how to generate the SHA1 fingerprint on different platforms one by one.

Windows

The keytool usually comes with the JDK package. We use the keytool to generate the SHA1 fingerprint. Navigate to the bin directory in your default JDK installation location, which is what you've configured in the JAVA_HOME variable, for example, C:\Program Files\Java\jdk 1.7.0_71. Then select, File | Open command prompt.

Now, the command prompt window will open. Enter the following command, and then hit the Enter key:

keytool -list -v -keystore "%USERPROFILE%\.android\debug.keystore" -alias androiddebugkey -storepass android -keypass android

You will see an output similar to this:

Certificate fingerprints:
    MD5:  55:66:D0:61:60:4D:66:B3:69:39:23:DB:84:15:AE:17
    SHA1: C9:44:2E:76:C4:C2:B7:64:79:78:46:FD:9A:83:B7:90:6D:75:94:33
