I’ve been using 4096-bit RSA SSH keys for quite a few years. The RSA keys are very compatible. They’ve been working on various operating systems as well as on mobile devices. They are also known as being slow and potentially insecure if created with a small amount of bits, especially after the year 2013.

Large keys are still considered secure, however the elliptic curve cryptography has become much more popular in the recent decade.

Due to a specific design requirements on a project I’ve been working on recently I needed to create a consistent system account on all the Linux servers across all the environments. This account supposed to have the following characteristics:
