Is it possible to bind an ssl certificate from a similar domain?

Question

Digital certificates

There are two domains.
They are similar, but differ in a couple of characters.
There is an SSL certificate for one domain.
This is one site.
Is it possible to put a certificate from the first one on another domain (another site)? Or is it impossible, each domain should have its own certificate for it? Please pay attention, these are not subdomains.

Example:
site.ru
si-te.ru

Answer 1

You can bind, but it will be invalid for browsers, so there is no point in this.

Answer 2

this is not possible, each domain must have its own certificate for it

Each domain has its own certificate, that's right.

Answer 3

You can, but the browser will issue a security warning every time. Personally, in such cases, if at least we are not talking about money transactions, I ignore it and go to the site anyway, although I try to make sure that there is a relationship between domains, but, I'm afraid, at least half of the visitors will be afraid or too lazy to confirm transition.
(The similarity of domain names obviously does not matter: for a computer, strings are either equal or not.)

Answer 4

If the certificate is yours (that is, there is a key file), it is possible, but meaningless - only one domain, which is registered in the certificate, will be valid.
If the certificate is not yours, you can't.
