Added more detailed JAR archive signature identification information
to TECHNOTE.DOC.
Fixed compatibility problem with QEMM. (Sometimes JAR refused to use
XMS memory under QEMM).
Fixed page fault when executing "test" command with archive argument
missing.
(*) NOTE: New "Authenticate" method details
JAR contains an exportable (from USA) archive protection method.
This method only checks for a valid archive password without using
actual data encryption.
In BETA_2, this method has been changed to permit ARJ Software to
distribute JAR decompressor sources without allowing access to
protected archive file data. A modified algorithm independent of
the password is used to access protected data. The decompressor
source will not contain this modified algorithm code.
This new method is called "Authenticate". The old "Authentication"
method is supported during updates and extraction but NOT for
the creation of new archives.
The "-hg0" option is the shortcut for "-hgAuthenticate".
We strongly encourage you to convert archives protected using the
obsolete "Authentication" method to the new method. The file
"convprot.bat" is an example batch file which may be used for
conversion. We apologize for any inconvenience caused by this
change.
