Encrypting PDF documents using macros

[ANaidoo]

Dear experts.

Please can you help me with this macro.
The below code converts the excel sheet to pdf. and then password protects the pdf. using passwords i already have in sheet1.

My problem is that, i already have hundreds of pdf. letters in a folder that i need to have it password protected. Is there anyway you can help with this?

it would be gratefully appreciated.
