The C preprocessor is worse than m4, and I would kill myself - before I had to use m4.

Prologue

-

- TOTP codes are pretty cool, and really easy to - do. They’re also the backbone of modern two-factor authentication. - With totp I hope to make - handling TOTP codes as easy and extensible as - possible. -

- -

Terminology

-

- There are a few terms that I will be using throughout this post, so it’s - good to make sure that we’re all on the same page about what I’m - referring to. -

- -
-
Secret
-
-

- Your secret is - a base32 encoded secret key that you should under - no circumstances share with anyone else. It is from this secret key - that we can generate valid TOTP codes. -

-
- -
Digits
-
-

- Your digits is the length of the generated - TOTP in digits. If digits is 8, - then your generated key could be ‘01234567’. When dealing - with 2FA this is typically 6. -

-
- -
Period
-
-

- Your period it the duration for which the generated key is - valid in seconds. When working with 2FA - this is typically 30. -

-
-
- -

Basic Usage

-

- totp takes secret keys as command-line arguments, but also - reads them from the standard input if none are provided. It assumes - that digits is 6 and period is 30. These defaults can - be changed with the -d and -p flags. -

Working with QR Codes

-

- Often times when enabling 2FA on your account - on some website or platform, you will be shown - a QR code you can scan with - your 2FA mobile application. - These QR codes - contain otpauth URIs. We can extract - these from downloaded images using utilities such - as zbarimg and use them in totp using - the -u flag to enable ‘URI mode’ -

-
- - …and that’s all! There’s nothing else you need. You can use secret keys - and otpauth URIs, and you can configure - the digits and period of the generated codes. You can - generate multiple keys at once, and all outputs are printed to the - standard output. -
