I'd like to inquire whether I can decrypt encrypted files through security. Acrobat doesn't have a detailed description. My goal is to determine whether the embedded script is available before the file is loaded. This will determine whether I decrypt the PDF. I hope I can get your help to solve the doubt. Thank you。

Acrobat SDK has no API option to decrypt a file, except by trying to open it.
