totper - the very simple totp cli

Very simple totp cli implementation, the real job is done by totp-lite

Usage

``` Usage: totper SECRET

   or pipe the input parameters

SECRET = Unpadded Base32 (RFC4648) encoded secret STEP = Seconds of step, defaults to 30 DIGITS = Number of digits in the result, defaults to 6 ALG = Algorithm SHA1, SHA256 or SHA512, defaults to SHA1 TIMESTAMP = UTC Unix timestamp in seconds, defaults to current

Note: practically all services use SHA1 as default

Examples: echo KZXW6ZDPN4 | totper 766369

totper KZXW6ZDPN4 766369

```

Install

cargo install totper

How to store secrets

I use this with GPG based pass password manager, which keeps the secrets in GPG encrypted files.

TODO:

• Read from stdin
• Maybe change the order of arguments, because secret should be read from STDIN practically always?
