SafeKuvert provides the user with the ability to encrypt, digitally sign, compress, and/or securely delete files from the hard disk. It uses the Public Key Infrastructure (PKI) built into Windows, standard X-509 certificates from any source including Active Directory, and support for AES, 3DES, DES, RC2, RC4 symmetrical encryption algorithms. The resulting encoded files are standard PKCS#7 messages saved in files with a ".pkcs7" extension.
