0 (0)

26 February 2020

Currently, I’m using KeePass as passwords, RSA-keys, and as the Freedesktop SecretService, see the KeePass: an MFA TOTP codes, a browser’s passwords, SSH keys passwords storage configuration and Secret Service integration post.

The idea is to move away from storing books in Google… Read More: Calibre Web: home in-browser online-library with Nextcloud storage and Moon+… »

As a follow-up to the SSH: RSA keys, and ssh-agent for SSH keys and their passwords management post. The idea now is to make simpler to work with password-protected SSH keys, to avoid the necessity to enter a password each time when you want to load a key to the ssh-agent.

One of the motives to go deeper into the keyrings (see the What is: Linux keyring, gnome-keyring, Secret Service, and D-Bus post) was the fact that Chromium, surprise-surprise, keep passwords unencrypted if a Linux system has no keyring and/or Secret Service enabled. So, let’s try to find how and where Chromium store passwords, and the… Read More: Chromium: Linux, keyrings && Secret Service, passwords encryption and store0… »
