SHA-1 fingerprint of keystore certificate

Question

Is the method for getting a SHA-1 fingerprint the same as the method of getting the a fingerprint? Previously, I was running this command:

It's not clear to me if the result I'm getting is the SHA-1 fingerprint. Can somebody clarify this?

Answer 1

If you are using Android studio this very simple.

Create a new Google map activity and you can see sha1 fingerprint like below image.

I am using Ubuntu 12.0.4 and I have get the Certificate fingerprints in this way for release key store on command prompt after generate keystore file , you can use this key for released app ,if you are using google map in your app ,so this can show the map properly inside app after release,, i got the result on command prompt below

administrator@user:~$ keytool -list -v -keystore /home/administrator/mykeystore/mykeystore.jks -alias myprojectalias

 
Enter keystore password:  ******

On Windows Platform we can get the keystore for debug mode by using the below way

C:\Program Files\Java\jdk1.8.0_102\bin>keytool -l
.android\debug.keystore -alias androiddebugkey -s

Answer 3

First there is same .jar file that in fb-sdk android-support-v4.jar.
Then generate SHA1 key using:

PackageInfo info;
try {

    info = getPackageManager().getPackageInfo(
        "com.example.worldmission", PackageManager.GET_SIGNATURES);

    for (Signature signature : info.signatures) {
        MessageDigest md;
        md = MessageDigest.getInstance("SHA");
        md.update(signature.toByteArray());
        String something = new String(Base64.encode(md.digest(), 0));
        Log.e("Hash key", something);
        System.out.println("Hash key" + something);
    }

} catch (NameNotFoundException e1) {
    Log.e("name not found", e1.toString());
} catch (NoSuchAlgorithmException e) {
    Log.e("no such an algorithm", e.toString());
} catch (Exception e) {
    Log.e("exception", e.toString());
}

Answer 4

keytool is a key and certificate management utility. It allows users to administer their own public/private key pairs and associated certificates for use in self-authentication (where the user authenticates himself/herself to other users/services) or data integrity and authentication services, using digital signatures.

For Windows

keytool -list -v -keystore "%USERPROFILE%\.android\debug.keystore" -alias androiddebugkey -storepass android -keypass android

Other

keytool -list -v -keystore ~/.android/debug.keystore -alias androiddebugkey -storepass android -keypass android

Authorization on Android uses a SHA1 fingerprint and package name to identify your app instead of a client ID and client secret.
