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:

k         


        

Answer 1

For those looking for a more recent location to install a windows binary version of openssl (32bit and 64bit) you can find it here:

An up to date list of websites that offer binary distributions is here

Answer 2

This works for me:

C:\Users\example>keytool -exportcert -alias androiddebugkey -keystore 
"C:\Users\example\.android" | "C:\openssl\bin\openssl.exe" sha1 -binary 
| "C:\openssl\bin\oenssl.exe" base64

Answer 3

Use the entire path, like this:

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

It worked for me.

Answer 4

First navigate to your Java/jre/bin folder in cmd cd c:\Program Files (x86)\Java\jre7\bin

Then use : [change debug.keystore path to the correct location on your system] install openssl (for windows 32 or 64 as per your needs at c:\openssl )

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

So the whole command goes like this : [prompts to enter keystore password on execution ]

c:\Program Files (x86)\Java\jre7\bin>keytool -exportcert -alias androiddebugkey
-keystore "C:\Users\vibhor\.android\debug.keystore" | "c:\openssl\bin\openssl.ex
e" sha1 -binary | "c:\openssl\bin\openssl.exe" base64
Enter keystore password:

Answer 5

I used this code:

This is worked for me successfully.

"C:\Program Files\Java\jdk1.6.0_26\bin\keytool.exe" -exportcert -alias sociallisting -
keystore "D:\keystore\SocialListing" | "C:\cygwin\bin\openssl.exe" sha1 -binary | 
"C:\cygwin\bin\openssl.exe" base64

Answer 6

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:

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, path that you will enter will be the path where you have installed the openssl...hope this helps..:-)

Edit:

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

OpenSSL for 64 Bits

OpenSSL for 32 Bits
