OTP Vault

This application allows one-time password (OTP) secrets to be securely stored and used to generate tokens. It borrows heavily from 99designs' AWS Vault.

Like AWS Vault, 99designs' keyring is used to provide multi-backend storage of OTP secret keys. go-otp provides OTP token generation.

Usage

Adding keys

# Add a TOTP key named 'my-totp' with secret key ABCD1234
> otp-vault add my-totp ABCD1234

# Add an HOTP key named 'my-hotp' with secret key ABCD1234, counter initialized to 20
> otp-vault add my-hotp ABCD1234 hotp 20

# Add a TOTP key with an 8-character length and 5-second period
> otp-vault add my-secure-totp ABCD1234 totp 0 15 8

Generating tokens

# Get a key for my-totp
> otp-vault get my-totp
< 123456 (2017-09-17 18:13:34.144377561 -0400 EDT)
