Android Facebook SDK: generate release key hash

Question

I\'m building an app in which users can log in with Facebook.

I\'ve created the hash keys like following:

try {
         PackageInfo info = getPackag         


        

Answer 1

keytool -exportcert -alias aliasName -keystore C:\my_release_keystroke_info.jks | openssl sha1 -binary | openssl base64

Answer 2

I find a solution. for MAC

Use this one to get YOUR_RELEASE_KEY_ALIAS:

keytool -list -keystore /Users/***/Documents/keystore/***.jks

and this one to get your release keyhash:

keytool -exportcert -alias YOUR_RELEASE_KEY_ALIAS -keystore /Users/***/Documents/keystore/***.jks | openssl sha1 -binary | openssl base64

It works for me.

Answer 3

We need to replace the word "openssl" by the path of one file inside the openssl structure.

So, My CMD command is:

C:\Program Files\Java\jre1.8.0_45\bin>keytool -exportcert -alias Informatheus -keystore C:\Users\Atendimento\Dropbox\AndroidKeystore\Keystore | C:\Users\Atendimento\Desktop\openssl\bin\openssl sha1 -binary | C:\Users\Atendimento\Desktop\openssl\bin\openssl base64

It worked.

Answer 4

The simplest way to get hash key released apk is : Get SHA1 key of released apk using following command:

keytool -list -v -keystore keystore_path.jks -alias keystoreAlias

Thn you will get SHA1 key. Copy that key and generate hash key using following site:

Link to get hash key

You will get Output (base64): copy it and use where you want..

Answer 5

This one is the easiest way i found so far for generating key hash!

try
{
  PackageInfo info = getPackageManager().getPackageInfo(
      "Your Package Name",
      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 (PackageManager.NameNotFoundException e) {

} catch (NoSuchAlgorithmException e) {

}
