How to encrypt the password vault so that multiple users can access it?

Question

Passwords

The task is something like this:
You need to create a password store with encryption so that the server does not store decryption keys and several users can decrypt the store without exchanging passwords with each other. It's just that I may not understand something in encryption, but it seems to me that two different keys can not decrypt the same thing either. Tell me how is this implemented? There are a couple of examples of such services on the Internet. For example blog.sibirix.ru/2016/09/01/keyrights-1.1.4

Answer 1

What encryption algorithm is suitable for access with multiple passwords?

Answer 2

Symantec encription can do it right off the bat... Create an encrypted file and open it with PGP keys or different passwords.
Some of the editions of this software are free (differences in functionality). Maybe this Wishlist is there.
Alas, there is a problem - a container already opened by one user cannot be opened by another.
