Openssl Is Not Recognized as an Internal or External Command

Openssl is not recognized as an internal or external command

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:

OpenSSL for 64 Bits

OpenSSL for 32 Bits

Powershell doesn't recognize openssl even after I added it to the system path

If you're running it in Powershell, check $env:path to be sure "C:\OpenSSL-Win64\bin" is in there. Previous comments all reference the PATH variable in in cmd.exe, which your error message suggests you are not using.

If it is not, run the following command in Powershell:

$env:path = $env:path + ";C:\OpenSSL-Win64\bin"

How to install OpenSSL in windows 10?

I also wanted to create OPEN SSL for Windows 10. An easy way to do it without running into a risk of installing unknown software from 3rd party websites and risking entries of viruses, is by using the openssl.exe that comes inside your Git for Windows installation. In my case, I found the open SSL in the following location of Git for Windows Installation.

C:\Program Files\Git\usr\bin\openssl.exe

If you also want instructions on how to use OPENSSL to generate and use Certificates, here is a write-up on my blog. The step by step instructions first explains how to use Microsoft Windows Default Tool and also OPEN SSL and explains the difference between them.

m164' is not recognized as an internal or external command, building OpenSSL using VS 2013 Developer Command Prompt

I got the same error 6/26/16. Apparently m164.exe is an assembler on AMD boards (I'm using Intel, where it is ml.exe). I was unable to work around it. But the 32 bit version doesn't have the same problem.
