Encryption and digital signature details and when introduced to PPT

[Mitch Gallant]

When was password-based encryption and digital signature capability
introduced to PPT? (what is minimum version that supports that)
Are there good articles discussing the digital signature embedding in ppt?
and encryption layout?

Ability to password files came with xp/2002. Passworded files will not open
in earlier versions.

It wasn't a problem. It was a general knowledge question.

It wasn't a question, it was a signature line. <G>
