- History of ProtEXE
- ------------------
-
- + addition
- - removal
- * change
- ! bug fix
-
- 3.10 Aug 1997
- More tricks to stop unpackers & debuggers, many new features,
- an interactive shell, a configuration file and some bugs fixed.
- + credit card ordering is now available - see ORDER.FRM
- + created commercial version without personalized registration
- + added code to stop 'universal' unpackers like UPC, CUP, TEU, ...
- + added anti-debugging tricks, especially designed to kill most
- commonly used debuggers (including Soft-ICE)
- + added a layer of polymorphic decryption
- + added -t option to tie program and decryption code together so
- that an unpacked version of the executable would never work {+}
- + added -s option and PTXCrypt programming libraries to allow
- registered users to dynamically encrypt their data {+}
- + added -r option to protect programs that stay resident (TSRs)
- + added -i option to add copyright info to the EXE header
- + added -ek option to keep the extra data at the old position
- + added -k option to keep the original code 100% intact
- * password option now available in the unregistered version also
- + the password prompt and error message can now be customized
- + can now wait for a keypress after banner and optionally echo
- the key pressed, attach a CR/LF and/or abort if ESC pressed
- * changed order of processing to crc error, registration info,
- banner, password
- * changed -eoh switch to -f to allow the 'fake header' option to
- be used without overlays
- * can now protect the DOS stub of new executables
- + registration validation now also shows timestamp code
- + added an interactive shell which allows you to browse through
- files and directories and interactively change all the options
- + added a configuration file to store often used options
- + added TestMsg tool to test the CRC failed message
- + added COM2EXE tool to convert COM files to EXE format (especially
- handy for COM files that would exceed 64K when protected)
- + included ComprEXE executable compressor and added it as the
- default to PACKERS.PTX (id 'c')
- - removed LZEXE from archive (replaced by ComprEXE)
- * changed COMPACK id from 'c' to 'cp' (to avoid conflict with ComprEXE)
- + added XPACK to default PACKERS.PTX
- + added a DESCRIPT.ION file with file descriptions for 4DOS
- + added a table of contents to the documentation
- * now displays two sets of statistics if a compressor is used:
- one relative to the packed file, and one relative to the source file
- * ProtEXE now works with PKLITEd executables that check their
- PSP signature
- * removed PROTEXE.FAQ and put the information it contained within
- the main ProtEXE documentation
- ! fixed bug with /eo feature that would let some EXE files crash
- ! fixed bug that caused the -h option (don't pack header) to be
- ignored when using a compressor
- ! fixed bug in the registration validation code that would sometimes
- cause problems (esp. Qemm386) after running PROTXVER on a program
- ! COM file overflow was not always detected for small overflows
- ! relocation table optimizations could theoretically create a
- relocation at offset 0FFFFh; this has been fixed now
- ! packer commandline is now treated case sensitive (in case a
- compressor requires case sensitive options)
- ! the executable's timestamp was sometimes touched because
- the file buffers weren't flushed yet; this is fixed now
- ! fixed bug that caused required memory paragraphs field to be too
- high in the protected EXE-files
-
- 3.01 Dec 1996
- Minor update to v3.0, not distributed
- + added code to stop UPC (universal program cracker)
-
- 3.0 Dec 1996
- Many new features were added & the security has greatly improved.
- + added -b option to display a bannerfile
- + added -p option to password-protect the executable
- + added -c option to call a compressor before protecting the executable
- + added -eo option to protect some hardcoded overlaid EXE-files
- + added -eoh option to fake the old EXE header to be read
- + added -ec option to CRC check extra data in EXE file {+}
- + added -h option to keep extra EXE header information
- + added -d option to protect device driver EXEs etc.
- + added ability to verify registration information
- * improved and added anti-debugging tricks
- * changed, improved and secured encryption system
- * messagefile may now contain $ characters & CRC failed message
- can no longer be suppressed with >NUL on the command line
- * the executable's timestamp isn't touched anymore
- * statistics have been reformatted and percentages added
- * improved error/warning handling for easier troubleshooting
- + support for / switch character as well as -
- - command line option -0 that got disabled in v2.12 is now
- completely removed
- ! using the single parameter form if the file with extension .OLD
- exists already now works correctly; also if an error occurs
- during the protection the original file will be left untouched
- and not renamed to .OLD anymore
- ! can now stably handle EXE files which rely on the stack segment
- displacement having a certain value (e.g. LHA & PKZIP SFX).
-
- 2.12a Jul 1996
- Minor update to v2.12, not distributed
- ! small bug in default msg in registered version fixed (would show
- some garbage after the actual message)
- * regkey may now be in PATH as well as in same directory as EXE
-
- 2.12 Jun 1996
- Another bug fix, ProtEXE is now stable
- ! problems with running in an OS/2 DOS box fixed
- - command line option -0 has been disabled
- * changed registration system entirely, now uses reg key
-
- 2.11 Feb 1996
- Major bug fix
- ! fixed bug that caused incompability with the Pentium processor
-
- 2.1 Dec 1995
- ProtEXE now supports both COM & EXE files
- + added support for COM files
-
- 2.0 Dec 1995
- Major new version, almost a complete rewrite
- + added lots of anti-debugging tricks
- * uses true CRC instead of checksum
- * improved encryption method, especially for long series of the same bytes
- - magic number option removed; program now automatically picks the
- encryption parameters at random so that everytime you run it a different
- EXE file is created
- - registered version no longer requires USER_ID.DAT; the user name is
- branded into the EXE file
-
- 1.1 May 1995
- First public release, complete rewrite
- * improved encryption method and checksum method
- + added ability to change checksum error message {+}
-
- 1.0 Mar 1995
- Original version, never released
-
- If you have any suggestions, I'd like to hear them.
