DecryptFileA
Document management, Security and Signatures
Description
The trailing A denotes the ANSI (char) DLL entry point; the ActiveX/COM surface exposes only the Unicode form. Behaviour is identical to DecryptFile and string arguments are interpreted using the current SetAnsiMode code page
This function attempts to remove the encryption from a file on disk, saving the decrypted document to a new file.
This function will succeed even if the user password is supplied (including an valid blank password) rather than the master password. Developers are advised that they should respect the security wishes of the document's author.
