OtpGenLib

OtpGenLib is a library built for generating and verifying One-Time Passwords (OTPs) using Elixir. The OTPs are securely hashed and expire after a configured timeout. This library is designed for authentication workflows where OTPs are required for user verification or transaction approvals.

Features

• OTP Generation: Generates a random 6-digit OTP for a given key (e.g., user email or ID).
• OTP Verification: Verifies the user-provided OTP against the stored OTP hash.
• OTP Expiry: OTPs automatically expire after a configured timeout (default: 30 seconds).
• Concurrency: Utilizes Elixir's GenServer for stateful, thread-safe operations.
• Logging: Logs OTP expiration events for monitoring and debugging purposes.

Installation

To add this library to your project, you can use the following in your mix.exs file:

defp deps do
  [
    {:otp_gen_lib, git: "https://github.com/rathi-abhinav/OtpGenLib.git"}
  ]
end
