keytool is located in JDK bin directory   JAVA HOME bin   JAVA HOME is your JDK installation directory  To use that command line you should also include  JAVA HOME bin to your PATH environment variable

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  -list -v

keytool comes with the JDK  If you are using cygwin then this is probably on your path already  Otherwise  you might dig around in your JDK s bin folder   You ll probably need to use cygwin anyways for the shell pipes     to work

Alternatively you can do the following    copy the bat file below in any folder already present in your PATH environment variable then simply use keytool command in any Windows shell  Actual location of keytool is defined in the bat file  In case the location is wrong the bat file will scan your system to detect potential locations in ProgramFiles  sub folders  Also find keytool2 bat  a convinient shortcut for  quot keytool -v -list -keystore quot   which is widely used to quickly check the content of a jks file  keytool bat                quot keytool alias quot  script by C  phas    easy method   add the known keytool exe folder to your personal PATH variable  run   C  Windows System32 rundll32 exe sysdm cpl EditEnvironmentVariables     else  add the folder containing this bat script to your personal path or put this script in any folder already defined in your path       also see keytool2 bat that automatically adds the following parameters in the keytool command line   -v -list -keystore  for quick display of jks content          echo off set THIS SCRIPT   f0 rem  setlocal enableDelayedExpansion   necessary for paths containing special chars setlocal enableDelayedExpansion  rem  set PATH to keytool exe   path must include the final   rem    is escape char for paths containing  amp     lt   gt       set PATH TO C  Program Files Java jre1 8 0 45 bin  set PROG NAME keytool exe  rem full path  with  quot  quot   to work with paths containing special chars set FULL KT PATH  quot  PATH TO  PROG NAME  quot   rem checks if keytool exe exists  dir  FULL KT PATH  gt nul 2 gt nul  amp  amp  set KT FOUND yes     set KT FOUND no  if  KT FOUND   yes       rem keytool found   gt  launching it with all supplied parameters     rem      rem      FULL KT PATH         rem     rem   else       rem keytool not found  trying to find it in  ProgramFiles       echo      echo Keytool not found in expected location  scan in progess         echo       cd  quot  ProgramFiles x86   quot  2 gt nul  amp  amp  dir  B  S keytool exe 2 gt nul      cd  quot  ProgramFiles  quot  2 gt nul  amp  amp  dir  B  S keytool exe 2 gt nul      echo      echo               echo Path to program keytool exe not properly defined  or keytool java missing on this system     echo If any location has been found during above scan  fix variable  quot PATH TO quot  in  THIS SCRIPT  accordingly     echo               echo      pause              keytool2 bat                quot keytool2 alias quot  script by C  phas    easy method   add the known keytool exe folder to your personal PATH variable  run   C  Windows System32 rundll32 exe sysdm cpl EditEnvironmentVariables     else  add the folder containing this bat script to your personal path or put this script in any folder already defined in your path       keytool2 automatically adds the following parameters in the keytool command line   -v -list -keystore    thus  to quickly display the full content of a jks file  usage is simply   keytool2  path to your keystore jks  -alias your alias           echo off set THIS SCRIPT   f0 rem  setlocal enableDelayedExpansion   necessary for paths containing special chars setlocal enableDelayedExpansion  rem  set PATH to keytool exe   path must include the final   rem    is escape char for paths containing  amp     lt   gt       set PATH TO C  Program Files Java jre1 8 0 45 bin  set PROG NAME keytool exe   rem full path  with  quot  quot   to work with paths containing special chars set FULL KT PATH  quot  PATH TO  PROG NAME  quot   rem checks if keytool exe exists  dir  FULL KT PATH  gt nul 2 gt nul  amp  amp  set KT FOUND yes     set KT FOUND no  if  KT FOUND   yes       rem keytool found   gt  launching it with all supplied parameters     rem      rem      FULL KT PATH  -v -list -keystore        rem     rem   else       rem keytool not found  trying to find it in  ProgramFiles       echo      echo Keytool not found in expected location  scan in progess         echo       cd  quot  ProgramFiles x86   quot  2 gt nul  amp  amp  dir  B  S keytool exe 2 gt nul      cd  quot  ProgramFiles  quot  2 gt nul  amp  amp  dir  B  S keytool exe 2 gt nul      echo      echo               echo Path to program keytool exe not properly defined  or keytool java missing on this system     echo If any location has been found during above scan  fix variable  quot PATH TO quot  in  THIS SCRIPT  accordingly     echo               echo      pause

Given that you have installed Java and preferably a JDK in your system   answering for Windows because you mentioned it in your question  you should have the keytool utility on your installation s bin folder    If that s the case  what you can do next is add that bin folder to the PATH environment variable of your Windows installation    The next time you will open a Windows shell and you ll type keytool you will be able to run the actual utility
