I have a vendor encrypting an xlsx file using McAfee E-Business server with PGP version 7.1.1 using the following command:

pgp --encrypt --sign --user ${vendorpgpkey} --passphrase InputFilename --force --overwrite --output OutputFilename

I am trying to decrypt the file using the following command.

gpg -d --output "${PGPDecryptedFileName}" "${PGPEncryptedFileName}"

This process works when the vendor is sending me .txt, .csv, or .pdf files. However, if they try to encrypt and send me a .xlsx file, the file is getting corrupted when decrypted.

The vendor is sending the file to me via SFTP using binary transfer.

I can encrypt the file on my local laptop and decrypt it without any issues so I'm assuming it's something related to how the vendor is handling encryption. I also checked Symantec help and couldn't find any leads.

Any help identifying the issue or pointing out additional debugging steps would be appreciated.

These files are really .zip files, so you can try to unpack the .xlsx file like a .zip and try if the password matches the used one. If unpacking will go well then there is problem with the content of the archive. If not - CRC checksum doesn't match the one in the file and you need to get file once again.
