I need to encrypt a string of 12 words securely with certain requirements:
- base64 cyphertext should easily fit in a QR code.
- brute-force hard due to lots of key stretching. I'm not going to use a crazy complicated password because I need to be able to get it in 10+ years if needed
- decryption software has to run on GNU/Linux (amd64) CLI
- can decrypt using only ubiquitous software. no scripts or custom shit. bonus if it's in the Debian repo
How can I do this?
inb4 openssl: no keystretching
inb4 gpg: has that stupid gpg-agent shit for gnome
inb4 truecrypt: botnet and won't fit on QR code

What is wrong with gpg-agent?

Keeps my password in memory. I'd rather something more straight-forward

I'm not an expert. I use gpg to encrypt files I store "in the cloud". So I'm not worried about a public key (symmetric password).
Does the following help?echo RELOADAGENT | gpg-connect-agent
