Write a terraform script where you create a linux ec2 instance with Security group and key defined so you should be able to use key to login to ec2 instance.

  
provider "aws" {

source = "terraform"{
version = "~> 2.8"
 }
}

resource provider "linux_security_group " allow key to login to ec2 instance"{

description = " allow key to login ec2 instance" 
}

region = "us-west-2" {
    access_key = "AKIAYIMEDZZZKEPKRNEM"
    secret_key = "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"

resource " aws_instance""first-ec2"{

ani = "ani-03d5c68bab01f3496" 
instance type = "t2.micro"
tags = {
   Name = "Anitha"
  }
}
}
