First you need to get the SHA-1. You can get it in different ways:

• On Google Play. On the left side menu go to Setup → App integrity, then select the tab 'App signing'
• From the apk itself with keytool -list -printcert -jarfile <my-apk-file.apk>

Once you have the SHA-1 you need to convert it to base64. There are various ways:

• node -e 'console.log(Buffer.from(process.argv[1].split(":").map(hex => parseInt(hex, 16))).toString("base64"))' 'PASTE_YOUR_SHA1_HERE'
