can't generate keyhash facebook

Question

I've tried to implement the following SO answer: Facebook Android Generate Key Hash.

13) Again copy following code and paste

openssl base64 -in debug_sha.txt > debug_base64.txt

When I try point 13 (above), I get the error:

openssl.exe has stopped working.

I've also tried using:

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

but I get the error:

Illegal option: Alami.android\debug.keystore keytool -list [OPTION]...

do you have openSSL downloaded in the system? – Silvans Solanki Mar 22 '16 at 11:20 — Silvans Solanki, Mar 22 '16 at 11:20

You can directly create it programatically.

Just add this code in your onCreate method.

try {
            PackageInfo info = getPackageManager().getPackageInfo(
                    "com.package.mypackage", 
                    PackageManager.GET_SIGNATURES);
            for (Signature signature : info.signatures) {
                MessageDigest md = MessageDigest.getInstance("SHA");
                md.update(signature.toByteArray());
                Log.d("KeyHash:", Base64.encodeToString(md.digest(), Base64.DEFAULT));
                }
        } catch (NameNotFoundException e) {

        } catch (NoSuchAlgorithmException e) {

        }

And you will get keyhash in Log.
