try to obtain the hash key on MAC for integrating facebook in my Android app

If someone has ever done this-obtained the hash key using the key tool on MAC please tell how u did it cause I'm pulling my hair out here.

Here is what I did:

First I found out that I should type these comands:

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

in my terminal in oder to get the hash key.

So I start typing:

 keytool -exportcert -alias androiddebugkey -keystore ~/.android/debug.keystore

As I pressed ENTER it asked for a password!

I gave up this and try to set a password to my keystore by doing this:

$ keytool -genkey -v -keystore my-release-key.keystore -alias alias_name -keyalg RSA -validity 10000

It asked for a password and the re-type password-All good until here.

The terminal also displayed this message:

[Storing my-release-key.keystore]

but it didn't tell where the keystore will be stored!!!

Now, I got the password and then tried again this magic command:

keytool -exportcert -alias androiddebugkey -keystore ~/.android/de开发者_如何学JAVAbug.keystore

It asked me for the password...I entered that and then it gave me this lovely little message thet drives me insane:

keytool error: java.io.IOException: Keystore was tampered with, or password was incorrect

So please if u know how could I obtain that key give me some details and I will appreciate it FOREVER.

Thank u in advance!

You generated a second keystore with your selected password, you did not change the password on the debug.keystore. AFAIK, the default password for the debug-keystore is android.
