Facebook needs 28 char long sha1 hash. Keytool generating 24 characters instead of 28

Question

In my app there is a facebook login. I would like to add an Android app to my facebook app which needs a hash generated with the keytool from the keystore file.

I can successfully generate a 28 character long hash from my production key but if I run the same command on my debug key, (which is the default android debug key) it only generates a 24 character long hash, which facebook does not let me input.

---

I use this command in windows' default cmd:

keytool -exportcert -alias androiddebugkey -keystore "C:\Users\myusernamehere\.android\debug.keystore" | "D:\Programs\OpenSSL\bin\openssl" sha1 -binary |"D:\Programs\OpenSSL\bin\openssl" base64

In the picture you can see that facebook doesn't let me enter other than 28 char long hash.

Any ideas?

Answer 1

The problem is the openssl

use the openssl-0.9.8e version

select your OS architecture if it is 32 bit then select openssl-0.9.8e X32

if your OS architecture is 64bit then select openssl-0.9.8e X64
