isEncrypted
A Boolean value specifying whether the document is encrypted.
Declaration
var isEncrypted: Bool { get }Return Value
true if the document is encrypted, whether it is locked or unlocked; false otherwise.
Discussion
If encrypted, reading the document requires a password.
Encrypted documents whose password is the empty string are unlocked automatically upon opening, because PDF Kit tries the empty string as a password if none is supplied. Use the unlock(withPassword:) method to unlock a document using a password.
