Is there a maximum length for the UNLOAD ENCRYPTED KEY value?

...as opposed to the usual fallback DECLARE @key LONG VARCHAR?

Hm, according to the underlying an_unload_db structure, it's a C "const char*", and the v17 topic on "Security: Keys for encrypted databases" says

Encryption keys are always case sensitive, and they cannot contain leading or trailing spaces or semicolons. Encryption keys can be of arbitrary length. Longer keys are better because a shorter key is easier to guess.

So I guess LONG VARCHAR is appropriate.

Nevertheless, it's astonishing that the data type is not explicitly mentioned for functions like ENCRYPT.
