OK so here is the Python code to password protect the PDF.
It takes 3 parms, -i is the input file, -o is the output file and -p is the
password.
import PyPDF4, argparse, sys
# initiate the parser
parser = argparse.ArgumentParser()
# add long and short argument
parser.add_argument("--input", "-i", help="Input PDF name.")
parser.add_argument("--output", "-o", help="Output PDF name.")
parser.add_argument("--password", "-p", help="Password.")
# read arguments from the command line
args = parser.parse_args()
if args.input is None:
print("Input file name is required.")
sys.exit(-1)
if args.output is None:
print("Output file name is required.")
sys.exit(-1)
if args.password is None:
print("Password is required.")
sys.exit(-1)
pdfFile = open(args.input, 'rb')
# Create reader and writer object
pdfReader = PyPDF4.PdfFileReader(pdfFile)
pdfWriter = PyPDF4.PdfFileWriter()
# Add all pages to writer (accepted answer results into blank pages)
for pageNum in range(pdfReader.numPages):
pdfWriter.addPage(pdfReader.getPage(pageNum))
# Encrypt with your password
pdfWriter.encrypt(args.password)
# Write it to an output file. (you can delete unencrypted version now)
resultPdf = open(args.output, 'wb')
pdfWriter.write(resultPdf)
resultPdf.close()
And the RPG that I use to call this Python script.

Hi Jose, i would love to see the rpgle executing python piece of code, if
you don't mind.
(for my own betterment)

Some time ago i have the same issue.
I decided install ibm i python. And now this is my run sequence:
1º RPGLE program generate a pfd file in a ifs folder,
2º The same RPGLE program execute a python script witch generate a copy of
pdf file (because i need so) protected with one password received by
parameter in the script.
First of all you need install python, and after build a script that work
for you.
it isn't complicated.
