Some quite important features added in response to queries and suggestions from
quite a few users.
Pass-phrase hash: A hash of the pass-phrase is now added to the end of the
plaintext before it is encrypted. This allows the
pass-phrase to be checked on decryption to make sure
that a wrong pass-phrase will not result in a garbled file.
Pass-phrase verify: An option has been added, in which the pass-phrase must be
entered twice before encryption is possible. This is to
ensure that the intended pass-phrase is used.
New blowfish module: This version now uses the Blowfish module by Gareth
McCaughan, which utilises CBC encryption to remove
the previous problems of repeated patterns.
Version 0.97 (released 18 March 1998)
============
This was a major update on the previous version, 0.95. The changes are listed
below.
PGP-enabled version: PGP IDEA processing has been added as an alternative
to Blowfish, for files which need ultimate protection.
This needs the PGP application which was converted
to Acorns by Gareth McCaughan and is available from:
<http://web.bham.ac.uk/N.M.Queen/pgp/acorn.html>
Options box : An options box has been added, to allow choice between
the two encryption methods, and also other options, which
have been added as described below.
Hide: There is now an option to replace the pass-phrase with
*'s, meaning that the pass-phrase cannot be read off the
screen as it is typed.
Warnings: There is also an option to turn off warnings that are
displayed when directories are processed and the warning
given when the original file is overwritten
General: The ram-transfer routines have been cleaned up, and
saving directories to another filepath now includes
all files, not just those processed. A link to the help
file and web-page have been added to the icon-bar menu.
Version 0.95 (1 February 1998)
============
Now supports directory processing, thanks to the routines from Mike Enderby of Integrated Systems Technologies <http://www.interpages.co.uk>
Version 0.91 (14 January 1998)
============
Uses the Blowfish method of file encryption for far safer files than the previous method. Thanks to WonderWorks <http://www.wonderworks.co.uk> for the PD blowfish module.
Version 0.85 (1 January 1998)
============
First internet release version, using the Encrypt module. A random seed has been added to the encryption to prevent null [00] bytes showing the passtext.
Version 0.8 (about January 1997)
===========
The ARM encryption code has now been placed in a module, accessed via an SWI.
Version 0.7 (about December 1996)
===========
All of the encryption routines have been re-written in ARM-code for increased speed (about 1000% increase)
Version 0.6 (about July 1996)
===========
Encryption routine changed to process files in memory, rather than byte-by-byte from disc (about 1000% increase in speed)
Version 0.5 (about March 1996)
===========
Desktop front-end re-designed completely.
Version 0.2 (about February 1996)
===========
First desktop version, comprising of a save-box and a writeable icon for the password.
