/*
|
|
* TOTP face
|
|
* Time-based one-time password (TOTP) generator
|
|
*
|
|
* Generate one-time passwords often used for two-factor authentication.
|
|
* The secret key must be set by hand, by editing "totp_face.c".
|
|
*
|
|
* Available algorithms:
|
|
* o SHA1 (most TOTP codes use this)
|
|
* o SHA224
|
|
* o SHA256
|
|
* o SHA384
|
|
* o SHA512
|
|
*
|
|
* Instructions:
|
|
* o Find your secret key(s) and convert them to the required format.
|
|
* o Use https://cryptii.com/pipes/base32-to-hex to convert base32 to hex
|
|
* o Use https://github.com/susam/mintotp to generate test codes for verification
|
|
* o Edit global variables in "totp_face.c" to configure your stored keys:
|
|
* o "keys", "key_sizes", "timesteps", and "algorithms" set the
|
|
* cryptographic parameters for each secret key.
|
|
* o "labels" sets the two-letter label for each key
|
|
* (This replaces the day-of-week indicator)
|
|
* o Once finished, remove the two provided examples.
|
|
*
|
|
* If you have more than one secret key, press ALARM to cycle through them.
|
|
* Press LIGHT to cycle in the other direction or keep it pressed longer to
|
|
* activate the light.
