ENCRYPTED E-MAIL ATTACHMENT PDF

[didemizer]

I am delighted to communicate my enthusiasm regarding the proposed measure to enhance the security of the payroll envelope mail that is slated for transmission within the Human Resources (HR) module. This enhancement involves the implementation of encryption to fortify the confidentiality and integrity of the sensitive information contained in the payroll documentation.

 

 

I have employed a third-party tool supplied by 'VeryPDF' to implement PDF encryption with a password.

 

For trial and more information you can check Download and buy VeryPDF Encrypt PDF .

 

Specifically, the 'Encrypt PDF Command Line' tool from VeryPDF facilitates the encryption of PDFs with a password through the Windows Command Prompt. We can easily trigger that tool from SAP. It is noteworthy that a trial version is available for testing purposes.

 

 

You may refer to the help file within the trial version of VeryPDF for comprehensive guidance and information. The assistance provided in the help file will offer insights into the features and functionalities of the trial version of VeryPDF

 

' Encrypt PDF software is a very flexible and powerful program, Encrypt PDF software allows you to encrypt

(using standard 40-bit or 128-bit supported by Acrobat Reader 5.0 and up) existing PDFs, set permissions,

add user and owner password. For example you can encrypt a PDF without to allow to print it. The button to

print the file will be disabled in Acrobat Reader application, you also can encrypt a PDF allowing the user

to read it only if he know the correct password. '

 

EncryptPDF -i c:\sample.pdf -o c:\out.pdf -w owner -u user -l c:\out.log

EncryptPDF -i c:\sample.pdf -w owner -u user -e 40 -p

EncryptPDF -i c:\sample.pdf -w owner -u user -e 40 -k -828

EncryptPDF -i c:\pdfdir\ -o d:\ -w owner -p -c -m -l c:\error.log

'

 

 

It is imperative to note that, prior to executing the external operating system command, the source PDF file, intended for encryption, must be meticulously created within the designated working directory.

 

 

 

We employ a comparable procedure for encrypting PDF documents. SAP offers the capability to execute external operating system commands either in the front end or in the background. The configuration of external commands can be accomplished using the transaction SM69.

 



 

 

Additionally, it is recommended to conduct a test to verify the feasibility of encryption through the command system. This will allow you to confirm the accuracy of your designated file path.

 

 

I have utilized the function module 'SXPG_COMMAND_EXECUTE' to execute the pre-configured external operating system command. An advantageous feature of this function module is its capability to execute the program in the background.
