Openssl is not recognized as an internal or external command

Question

I wish to generate an application signature for my app which will later be integrated with Facebook. In one of Facebook's tutorials, I found this command:

keytool -exportcert -alias androiddebugkey -keystore ~/.android/debug.keystore | openssl sha1 -binary | openssl base64

In the tutorial, it says that by running this cmd, my process of generating the signature will start.

However, this command gives an error:

openssl is not recognized as an internal or external command

How can I get rid of this?

Answer 1

Well at the place of OpenSSL ... you have to put actually the path to your OpenSSL folder that you have downloaded. Your actual command should look like this:

keytool -exportcert -alias androiddebugkey -keystore ~/.android/debug.keystore | "C:\Users\abc\openssl\bin\openssl.exe" sha1 -binary | "C:\Users\abc\openssl\bin\openssl.exe" base64

Remember, the path that you will enter will be the path where you have installed the OpenSSL.

Edit:

you can download OpenSSL for windows 32 and 64 bit from the respective links below:
