Hi all,

while playing with TOTP https://github.com/706f6c6c7578/TOTP I thought
it may be useful to have an option to generate deterministic passcoded,
valid for 24 hrs, instead of using passwords, for symmetric encryption.

$ dpass -h
Usage: dpass [options]

Options:
-p string
Shared password for deterministic passcode generation
-s string
Shared salt for deterministic passcode generation
-l int
Length of the generated passcode (Default 16)
-h
Show this help message and exit

$ dpass
Enter the shared password: test
Enter the shared salt: test
Passcode (16 characters): 4PFVCHS4DMZTPAZG
Valid from 2025-02-23 00:00:00 UTC to 2025-02-23 23:59:59 UTC.

What do you think about using passcodes for symmetric encryption?

Regards
Stefan

Entering passwords in commandline is a heresy.

How do you do that with GnuPG when using symmetric encryption?

I am not entering passwords in commandline.
I am entering them interactively in GPG TUI.
