Thanks for the pdf tools and it was working awesome. I have been using this tools since 2 yrs and it works really great than other paid version tools.

Now my issue is I'm trying to decrypt pdf ie..unlocking pdf using password and the file looks good but the file name after unlocking looks gibberish as you can see the image in he attachment.

This is what I'm trying to unlock pdf document:

Dim loadedDocument As New PdfLoadedDocument(inputPath, UnlockPassword)
 'Change the user password 
Dim security As PdfSecurity = loadedDocument.Security
security.UserPassword = String.Empty
security.Algorithm = PdfEncryptionAlgorithm.AES
security.KeySize = PdfEncryptionKeySize.Key128Bit
 security.Permissions = PdfPermissionsFlags.Default
'Save the password removed PDF document

Hi Ravi, 
I have checked with the below code snippet but it is working fine as expected. Can you please send us the value in ‘outputPath’ and the input document if possible, so that we could reproduce it from our side and provide you a solution.

Hi Karthikeyan,

Thanks for your reply. The output path is nothing but the path where the converted file is stored
Here is the path : "C:\Users\XXX\Desktop\mysite\downloadedfiles\40do7Zb5.pdf"

Please see the attachement for the file.

Password for the pdf file :

Hi Ravi, 
We could not see the password for the document which you sent in the last update. However, we have tested this code snippet with a sample document and it is working fine. I have sent you a simple working sample for your reference. Can you please check in it and let us know the result.

Hi Ravi, 
This issue is not reproduced from our side, we have created a sample and attached for your reference. Can you modify the sample to reproduce it, so that we could analyze it further.
