How to make an encrypted area on hdd?

Question

System administration

It is necessary to make an encrypted area on the external hdd - a partition or just a file system in a file.
The main condition is the ability to access encrypted data on a computer that does not have administrator rights.
That is, to access data, you simply need to run some program in the unencrypted part. Without installing drivers, programs, etc., which a user with limited rights cannot do.

Answer 1

The simplest is an archive with a password. Everything that will interfere with the work of the file system (encrypt on the fly) will require the installation of drivers and, therefore, admin rights.

Answer 2

look at VeraCrypt

Answer 3

Windows itself knows how to encrypt perfectly - you set an attribute on a directory / file and that's it.

Answer 4

Will Hide Folders work? If not, then programs with high-level crypto protection.
