Wrong passwords in MSSQL, how to fix?

Question

SQL Server

There is a task to correct a problem of storage of passwords in MSSQL.
The problem is this, as far as I understand:

declare @hashpswd nvarchar(128)
set @hashpswd=HASHBYTES('SHA2_512', '[email protected]')
select @hashpswd as hashpswd

This code will produce shortcodes instead of a normal hash because HASHBYTES returns varbinary data.
Now the question is, how can I make these shorthands in any scripting language in a readable form as they should be if the hashpswd variable is correctly declared?
This is the type of result you should get -
