PGP Encryption Utilities

Hi everyone 

After doing some tests (after your last delivery), we have a new error happening everytime when trying to decrypt a file without creating a new file.

The error message is always : Changed to Invalid UTF-8 input

Here are detailed logs : 

decryptedFile = KeyBasedLargeFileProcessor.decryptFileWithExtension(cs.getDocumentInputStream(fileToDecrypt), cs.getDocumentInputStream(privateKey), pwd.toCharArray(), decryptedFileName, existingDocument, createNewDocument, saveToFolder, cs);
