**Beginner to React native** 

I am trying to verify `OTP` automatically using `react-native-sms-retriever`
I have implemented following example in project

[Example implemented](https://www.npmjs.com/package/react-native-sms-retriever) This exampleis not provudung way to get hash key. you have to get it manually by executing command

When I execute command, it won't ask for password. It should ask [because of here it is](https://github.com/Bruno-Furtado/react-native-sms-retriever/issues/4#issuecomment-508026734)

```
keytool -exportcert -alias androiddebugkey -keystore '~\.android\debug.keystore' | xxd -p | tr -d "[:space:]" | echo -n com.opick.app cat | sha256sum | tr -d "[:space:]-" | xxd -r -p | base64 | cut -c1-11

```

How to generate hash key for release build tried following returns wrong key

```
keytool -exportcert -alias my-key-alias -keystore my-key.keystore | xxd -p | tr -d "[:space:]" | echo -n com.opick.app `cat` | sha256sum | tr -d "[:space:]-" | xxd -r -p | base64 | cut -c1-11

```

I have read document they says you need to add `path` for `release keystore` in above command.for me i is not working please update on same 

Main challenge is the generated key is different on `cmd` and `bash`
