Removable Storage Protector is a kernel driver utility, when active, it encrypts everything that goes to your USB flash stick. The files on the flash stick can only be decrypted on machine that has RSP installed with the correct password. RSP applies UniSoft concept "Security Should be Seamless". With the AES-256 encryption, If your flash stick is lost or stolen, it would require computer processing resources many orders of magnitude beyond current capabilities. However, RSP provides privacy protection, It does't prevent the deletion of files from the flash stick nor provides physical protection. In other words, someone who steals the flash drive would be able to destroy the contents of the flash stick, rather than being able to read its contents.
