SubRosaSoft Ships CipherDisk 1.0
— Live – transparent – encryption for OS X —

Bay of Plenty, New Zealand, (December 2nd, 2003)—,
Ltd., a software company based in New Zealand focusing on privacy and
system utility software, today announced the immediate availability of
CipherDisk=FA. CipherDisk allows bullet-proof protection of data on
internal drives, external firewire or USB drives, and CD/DVDs from
prying eyes.

SubRosaSoft CipherDisk provides "driver level" 448-bit
transparent on-the-fly encryption for OS X volumes. Once you convert a
plain volume to an encrypted volume, it will be inaccessible
to anyone until you enter a password to unlock it. When unlocked, the
drive will run and behave normally like a regular volume.

"A lot of encryption products are cumbersome to use, requiring a
user to create virtual volumes of disk images. On CipherDisk, we
strived to deliver a product that users could use without having to
learn anything extra, whilst providing the strongest encryption."
Said Marko Kostyrko, co-author of CipherDisk and CEO of

very conscious of our rights to privacy–I am proud to deliver this
technology to the entire world and yet achieve the most transparent
product. CipherDisk is an essential tool in protecting your data from
prying eyes." Concluded Ben Slaney, co-author of CipherDisk.
