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 OS X, 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, Mac OS 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.
