How To Fix ylva: command not found in Ubuntu / Debian / Kali Linux / Raspbian

In Ubuntu ylva is provided by ylva package.

ylva is:

Ylva is an old Swedish female name, it means “she-wolf” a derivative of Old Norse úlfr. When it comes to the password manager, before the release 1.4, Ylva was known as Titan.

Password management belongs to the command line, deep into the Unix heartland, the shell. Ylva makes managing passwords easy and secure. It’s a traditional command line software written in C. Ylva is very portable and should run fine on most Unix-like operating systems. Ylva is mainly developed on Linux.

Command line password manager is useful. You may choose to run it on a remote server to make your passwords available remotely (over SSH etc.). No need to sync your password database between machines.

Ylva uses OpenSSL (or LibreSSL) for encryption. For password database SQLite is used. Ylva encrypts the database using AES with 256 keys. Encrypted database is authenticated using HMAC. For key generation PKBDF2-SHA256 is used with 200 000 iterations.

Ylva does not stay running, so possible plain text passwords are not in memory except for a very short while. For example, running command ylva –auto-encrypt –list-all would list all the password entries, encrypt the database and then exit. Plain text passwords will be in memory only couple of seconds. This makes it very hard for malware to steal them.

When the database is decrypted, it’s readable only by the owner (chmod 600). Ylva does that automatically for the database file so you don’t have to change the permissions.

To fix this problem, we can install more using the command below.

sudo apt-get -y install ylva

This command might take some time to finish depending on your machine internet connection.

You can also use apt command to install ylva.

sudo apt -y install ylva

Or if you have aptitude installed you can use the following command.

sudo aptitude install ylva
