Vulnerability discussion

If unencrypted files are intercepted, sensitive information in the files can be compromised. To protect information confidentiality, Microsoft Office application files can be encrypted and password protected. Only users who know the correct password will be able to decrypt such files. Since some encryption types are less secure and easier to breach, Microsoft Enhanced RSA and AES Cryptographic Provider, AES-256, 256-bit should be used when encrypting documents.
