CoverUp is a files encryption software with additional file hiding utility. It uses a proprietary dual-keys multi-stage file encryption algorithm that securely encodes data in files to avoid being read by unauthorized users. Multiple files can be encrypted at one go. Moreover, CoverUp allows a file to be secretly hidden behind another normal looking file called the carrier file. The carrier can be JPEG, MPEG, HTML, .xls or other file types. This file hiding utility further enhanced and strengthened file security.
