What is Sentry 2020?
Sentry 2020 provides encrypted virtual volumes. All information (files,
folders, file system structures) stored on a Sentry volume is transparently
encrypted/decrypted every time an application performs a read/write operation
on the volume. Without a correct password, Sentry volume is just a file
with encrypted contents. When the correct password is provided, the volume
is mounted, and appears as a drive letter (Win 95/98, Win NT) or as a folder
in the root directory (Win CE). Any application can then work with the
contents of the mounted Sentry volume without noticing the encryption being
performed on the fly.
When mounted, a virtual volume looks like an ordinary disk and you can
store your files on it. Every read operation on the volume causes decryption
of the data and every write operation causes encryption. This approach
is called "transparent encryption" and insures that your data is always
stored in a safe, encrypted form, and yet appears in its natural form when
you wish to use it.
