i have problem that i dont know how to solve!!i try to fix it almost a week.

i have application in google play, and i try to do google sign in authentication.

the problem is in the SHA-1.

when i use the keytool command on the keystore file to get SHA-1 relese i get something that start with 28.

when i do intagretion in firebase to link to Google Play,it take another SHA-1 that start with B0, like the image below:

there is anyway to change the SHA-1 in the google play application? to solve this?

in the app folder i have the file google-service.json and i put the correct SHA-1, the one who start with 28, but it didnt help, when i do line its still take the SHA-1 who start with B0..

i will be thankfull for any help!

thanks!

EDITi want to make google sign in and get ApiExeption 10. this is because the SHA-1.i want to change in the console play like the image below:

with what i read in some other posts, i see that i cant do it.

there another way still make google sign in with my application?i have both 28 and B0 in firebase, google-service.json and google devloper API.

maybe i dont know which one i need to put in this code:

// Configure Google Sign InGoogleSignInOptions gso = new GoogleSignInOptions.Builder(GoogleSignInOptions.DEFAULT_SIGN_IN)        .requestIdToken(*28 or B0?????????*)        .requestEmail()        .build();

I'm making a php login, and I'm trying to decide whether to use SHA1 or Md5, or SHA256 which I read about in another stackoverflow article. Are any of them more secure than others? For SHA1/256, do I still use a salt?

Also, is this a secure way to store the password as a hash in mysql?

function createSalt(){    $string = md5(uniqid(rand(), true));    return substr($string, 0, 3);}$salt = createSalt();$hash = sha1($salt . $hash);

How can I get the sha-1 fingerprint, as here:

// A.T. C.     { { { 0xf9, 0xb5, 0xb6, 0x32, 0x45, 0x5f, 0x9c, 0xbe, 0xec, 0x57,    0x5f, 0x80, 0xdc, 0xe9, 0x6e, 0x2c, 0xc7, 0xb2, 0x78, 0xb7 } },{"1.3.6.1.4.1.34697.2.1", ""},  },

from Chromium source (net/cert/ev_root_ca_metadata.cc). If the Crypto?

When I try, I always get this

04:A0:56:A9:87:64:BB:DC:96:BF:6D:B0:49:FA:80:81:ED:06:8A:1E

Which program can I use for this and what is the name of the command, to get this in crypto?

EDIT

I will add a certificate as EV in firefox / chromium.

I'm trying to create a dynamic link in Firebase, when I'm selecting the android app, it shows an error saying "Add SHA-1 to this android app", I've already added a credential, but I'm not sure how exactly do I "add SHA-1 to the app"

How is this done?

SHA1 is completely insecure and should be replaced.

This question is 8+ years old and times have changed: https://arstechnica.com/information-technology/2017/02/at-deaths-door-for-years-widely-used-sha1-function-is-now-dead/

For passwords: https://en.wikipedia.org/wiki/PBKDF2

For data: SHA3

SHA512 is more complex than SHA1, but how much security am I losing by hashing a salted password with SHA1 compared to hashing it with 512? in terms of the time it would take for someone who has the db to crack a single password. I'm using a framework that doesn't give me easy access to SHA512, I'd have to override stuff to make it work, so I'm thinking to just use SHA1, though in the past I've always used SHA512.
