EncryptPad
Version: 0.5.0.3 Web: https://evpo.net/encryptpad
Although it’s not a good idea, many people still continue to store passwords in plain text files. While we won’t force you to trust and offload the credentials to a third-party password manager, we’ll suggest you at least encrypt those text files for an additional level of security. Better still, use an encrypted text editor such as EncryptPad to safeguard the sensitive info.
The cross-platform EncryptPad has binaries for Ubuntu and Linux Mint that you can install from a PPA:
$ sudo add-apt-repository ppa:evpo/main
$ sudo apt update
$ sudo apt install encryptpad encryptcli
Users of other distros can use the official AppImage. Just grab it from the project’s Download section, make it an executable from the file manager or with the
chmod +x command, and then double-click to launch the app.
On launch, the app looks like a standard vanilla text editor. By default, EncryptPad doesn’t have a password or a key, as highlighted in red in the status bar.
Use the editor to open a regular text file, or enter some text in the app. When you are done, you can lock it by heading to Encryption > Generate Key. Browse and select the path where you want to store the key, then specify the filename of the key. You’re now prompted to enter a passphrase, after which the app generates a key for the text file.
When you now save the file, it prompts you to enter the name for the text file, which has the .epd file extension. After you’ve specified the filename, the app prompts you to define a passphrase to add another layer of protection.
To open the encrypted EPD text file, you’re prompted for both the passphrase as well as the key with which you’ve locked the file.
