July 27, 2018: Release 1.11
This release fixes a number of minor portability issues and minor
bugs. In cat and unixcrypt modes, "-" can now be specified as a
filename to mean standard input. The emacs mode has been updated for
compatibility with Emacs 26. Estonian translations were added. Thanks
to Hugh McDonald, dcb314, d8uoba, Zhang Jun, and Duncan Bayne for
reporting bugs, and to Estprog for the Estonian translation.
October 18, 2012: Release 1.10
This release fixes a number of minor portability issues and minor
bugs. The ccrypt core functionality has been factored into a
convenience library libccrypt.a. A ccguess program was added to
assist in the recovery of mistyped keys. Improved error checking and
fixed minor compiler warnings. Minor improvements to emacs support,
and added a --disable-emacs configuration option. Thanks to
bornlibra23 and Johannes Ruscheinski for bug reports.
August 28, 2009: Release 1.9
This release fixes a number of portability issues. There is no change
in functionality relative to release 1.8. However, compilation errors
on several platforms have been fixed, including Mac OSX, Ubuntu,
FreeBSD, and Solaris 10. Also, rudimentary OS/2 support via EMX has
been added. Thanks to Lester Ingber, Elbert Pol, and Michael Annino
for reporting problems and helping to fix them.
June 5, 2009: Release 1.8
This long-overdue release fixes some minor bugs and adds minor
features. Added a new --keyref option to avoid double password
prompt. Added a new exit code in case the key was not entered or not
found. Added internationalization support and German and French
translations. Fixed minor bugs in user interface and updated emacs
support. Password files ending in a DOS-style end-of-line marker are
now correctly recognized. Improved portability and testing.
March 28, 2004: Release 1.7
Large file support now works under cygwin. Prompting twice for
encryption passwords is now the default. Added --disable-libcrypt
option for systems where libcrypt is broken.
August 26, 2003: Release 1.6
Fixed a potential (but rare) segmentation fault.
August 25, 2003: Release 1.5
Numerous improvements to the code and some bug fixes. --mismatch
option now works again. Ccrypt now also compiles under the gcc-3.3
compiler and the cc compiler. Return values were made more
meaningful. Autoconfiguration has been improved, and a new
--with-lispdir configuration option was added. The "check" target
has been improved to work on more machines. Some bugs in emacs
support were fixed.
March 29, 2003: Release 1.4
Ccrypt now handles files larger than 2GB. Also, a much-requested new
option --tmpfiles was added which causes ccrypt to use temporary
files during encryption, rather than overwriting the old file
contents destructively. This is less secure than the default
behavior, but it prevents data loss in case of an interruption or a
crash during crypting.
September 26, 2002: Release 1.3
This release improves the speed of ccrypt by about 20-30% (in file
mode), 45-50% (in filter mode), and 85% (in unix crypt mode).
Encryption and decryption functions have been separated out into a
library ccryptlib which can be used by other GPL-compliant programs.
Encryption/decryption of write-protected files is now possible. Some
bugs in adding/removing filename suffixes were fixed, and a new
option --strictsuffix was added. Command line options were added to
specify the second key in keychange mode. Pseudorandom number
generation was improved by taking into account the current time in
microseconds, not just seconds. The --timid option now also applies
in filter mode. Autoconfiguration was improved.
January 29, 2002: Release 1.2
This release provides vastly improved encryption/decryption speed. By
optimizing one critical inner loop, ccrypt now runs about 2-3 times
faster than the previous release. The only other changes were some
minor improvements to the autoconf scripts. No new features were
added.
November 28, 2001: Release 1.1
There are two major changes in this release: first, I have added an
option --unixcrypt, which allows the decryption of files that have
been encrypted with the old unix "crypt" utility. Since the cipher
used by "crypt" is broken and no longer secure, it is recommended
that all such files should be converted to the ccrypt format. The
second change is that ccrypt is now configured using the
automake/autoconf tools. This should make compilation and
installation a lot more standard and portable. This release of ccrypt
compiles under Linux, SunOS, MacOS X, FreeBSD, AIX, and CygWin with
no problems, and it should be portable to other systems with no or
few changes. I have also added some tests that can be invoked by
"make check", which check that ccrypt is working properly.
October 30, 2001: Release 1.0
This is the first public release of ccrypt. It fixes the file format
and the basic user interface. All future releases of ccrypt will be
backward compatible with this format, i.e., they will be able to
decrypt files that were produced by earlier releases.
