Seal is a simple program to encrypt files, notes, and passwords. Seal depends on the vis editor because vis can be used in a pipe without writing temporary files. Install vis by compiling it from source or using your package manager:
| Distro | Command to install Vis |
|---|---|
| Arch Linux | pacman -S vis |
| Debian | apt-get install vis |
| OSX | Homebrew pull request |
If you have any ideas on how Seal could use Vim without writing data in cleartext to disk, let me know!
Install Seal and generate your private key:
$ go get github.com/davidlazar/seal/...
$ seal-keygen
Created directory /home/david/.seal
Enter passphrase:
Enter same passphrase again:
Wrote public key: /home/david/.seal/david.publickey
Wrote private key: /home/david/.seal/david.privatekey
Backup your private key:
$ cp ~/.seal/david.privatekey /mnt/usbkey
$ lpr ~/.seal/david.privatekey # print the private key
Encrypt a file:
$ seal example.pdf
Wrote example.pdf.sealed (encrypted with key david)
$ rm example.pdf
Reveal the contents of the encrypted file:
$ seal-cat example.pdf.sealed | zathura -
Enter passphrase for key david: ...
Seal can create and edit encrypted documents. You do not need to enter a passphrase to create an encrypted document:
$ seal-edit doc.txt.sealed # launches the vis editor
Subsequent edits require a passphrase:
$ seal-edit doc.txt.sealed
Enter passphrase for key david: ...
The seal-pw program can be used as a password manager.
To generate a password for a new account:
$ seal-pw github # launches the vis editor to specify account information
Run the same command again to copy the password to the clipboard:
$ seal-pw github
Enter passphrase for key david: ...
url: github.com
username: davidlazar
Password copied to clipboard for 10 seconds.
Use seal-cat and seal-edit to view and update account information:
$ seal-cat github
Enter passphrase for key david:
url: github.com
username: davidlazar
