'".. is not recognized as an internal or external command, operable program or batch file." error when running keytool to create SHA1.

To login with Facebook, I had to create a SHA1 signature for my application when I started using the Facebook API. When I tried to prepare this signature according to the instructions, I got the following error.

First of all, this was the code I had to run for the Facebook API.

keytool -exportcert -alias androiddebugkey -keystore "C:\Users\USERNAME\.android\debug.keystore" | "PATH_TO_OPENSSL_LIBRARY\bin\openssl" sha1 -binary | "PATH_TO_OPENSSL_LIBRARY\bin\openssl" base64

When I get this code in the proper format and run it, the following error occurs.

As a solution to this problem, I wrote that path, thinking that it wanted the path of the openssl.exe program in that folder, not the path to the openssl folder. And as a result, the problem was solved.
