Irrespective of this discussion, a single salt value for all you entries
is discouraged. It's better to have one salt value per entry. Some
algorithms even embed the salt in the encrypted value itself so that
everything is stored in a single column.

In an ideal world, you would keep the salts in a separate structure
altogether but the embedded salt per entry is a near second in case the
whole dataset is being brute forced.
