You don't need Eclipse.
The information below is a short version of the Guide/Facebook page of the help files, plus a little extra for creating the keystore.
You can set up the Java SDK (from Oracle site) and
Openssl
In Java bin library (for your installation), run:
C:\Program Files\Java\jdk1.8.0_31\bin>keytool -v -genkey -v -keystore "c:\keystore\my.keystore" -alias myalias -keyalg RSA -validity 10000
Java location may differ for release and your install location.
my.keystore is your keystore name and location
myalias is your alias
For the hashkey:
In Java/bin library, run:
C:\Program Files\Java\jdk1.8.0_31\bin>keytool -exportcert -alias myalias -keystore "C:\my.keystore" | "c:\OpenSSL\bin\openssl" sha1 -binary | "C:\OpenSSL\bin\openssl" base64
Again, change the paths and names to suit your instalaltion
I did this about a week ago and it worked ok. It took me about 2 hours to work it all out, hopefully this shortcuts the process for you!
