I'm trying to create a hash key for my android app for facebook intergration

I've gone to the directory where the keytool is located at:

C:\Program Files\Java\jdk1.8.0_161\bin

I've used the following command to to try to generate the key:

keytool -exportcert -alias androiddebugkey -keystore %HOMEPATH%\.android\debug.keystore |
    C:\OpenSSL\bin\openssl sha1 -binary |
    C:\OpenSSL\bin\openssl base64

However, I get the error after entering a password

openssl:Error: 'g√╓çtΩ┤N▀Kptε╫π∞' is an invalid command.

I've noted the command changes depending on the password. If I leave the password empty I get 

openssl:Error: '\Fà»T' is an invalid command.

I'm using android 2.3.3

Any advice or help would be appreciated as I'm stumped and have found nothing online

For anyone in the present day who might be running into this, make sure base64 is included at the end of the command. it is getting cut off when I paste the command into my terminal. So it should look like this:

keytool -exportcert -alias androiddebugkey -keystore %HOMEPATH%\.android\debug.keystore | openssl sha1 -binary | openssl base64

This previous question can be useful for your case:

RELEASE_KEY_ALIAS and RELEASE_KEY_PATH values for generating key hash

I had this problem. The issue was because I was running the command in the wrong directory. Use the folder that has java/bin Initially I used C:\Program Files (x86)\Common Files\Oracle\Java\javapath After solving I used C:\Program Files\Java\jdk1.8.0_201\bin
