Registry keys and values
AxCrypt keeps some persistent data and chosen options in the registry. Most of these
are managed automatically, and should not be modified manually.
Some values under HKEY_CURRENT_USER\Software\Axon Data\AxCrypt\ are:
AllowAnyExtension is a DWORD that when non-zero causes AxCrypt to allow
any extension of files to be decrypted. The default is to assume that if this happens
it's because of a faulty association, and thus give a message to this effect.
BruteForceCheck is a REG_SZ that maintains the most recent check-point
in a custom brute force key-recovery search. See the code for details. This is not
for ordinary mortals. Please don't waste bandwidth hollering 'back-door' without
understanding what this is about. It's not. For questions, please contact me directly.
CompressThreshold is DWORD that indicates the minimum estimated compression
level needed for AxCrypt to compress before encryption. To disable compression,
set the value to 101. To enable compression in all cases, set it to 0. The default
is 20, indicating that at least estimated 20% savings is required for compression
to be performed.
DisableRenameMenu is a DWORD when non-zero causes the anonymous rename
menu to disappear from the right-click context menu.
EventLogLevel is normally zero DWORD, causing nothing to be logged, unless
server mode is enabled. You may increase this to positive values to get increasing
levels of detailed log-entries in %TEMP%\AxCrypt.Log. This is primarily for testing
and debugging purposes.
EntropyPool is 128 byte BINARY used to persistently save the state of
half of the entropy pool.
KeepTimeStamp is a DWORD that when non-zero will ensure that the encrypted
file always has the same time-stamp as the plain-text file. When zero (default),
the time stamp will reflect the time of last encryption - not the time of last modification
of the plain-text.
KeyWrapIterations is a DWORD that specifies the number of rounds performed
in the key-wrapping operation, where the actual master data encrypting key is wrapped
with the SHA-1 hash of the pass phrase. The minimum value is 6, no maximum, except
it may take a long time...
Licensee is a REG_SZ containing the name or identifying string for the
licensed user. This setting may be override an entry in HKLM.
NoUnsafeWipeWarn is a DWORD that when non-zero disables the warning about
not being able to securely wipe certain types of files, notably compressed and EFS
encrypted. This is modified by the checkbox in the warning dialog.
SaveDecKey is a DWORD that when non-zero causes decryption pass phrases
to be cached in memory. This is modified by the checkbox in the enter pass phrase
dialog.
SaveEncKey is a DWORD that when non-zero causes an encryption pass phrase
to be cached in memory and be used as default encryption pass phrase. This is modified
by the checkbox in the enter pass phrase dialog for encryption.
ServerMode is a DWORD entry, that when non-zero causes AxCrypt to enter
a non-interactive server mode. In this mode, no message boxes or dialogues will
be displayed. The messages will be logged to %TEMP%\AxCrypt.Log, and
they will be given default responses. The shell extension, i.e. the right click
menu in Windows Explorer with AxCrypt options will be disabled as well.
Signature is a REG_SZ containing the base 34 string representing the
digital signature that verifies the licensee. This setting may be override an entry
in HKLM.
TryBrokenFile is a DWORD that when non-zero makes AxCrypt give the user
the option to try decrypting a file, even if it appears broken. Use only for data-recovery,
and at your own risk, and always on a copy of the file in question.
Some values under HKEY_LOCAL_MACHINE\Software\Axon Data\AxCrypt\ are:
Licensee is a REG_SZ containing the name or identifying string for the
licensed user. This setting may be overridden by an entry in HKCU.
SelfExtractorName is a REG_SZ that contains the name of the executable
base file used for self decrypting archives. This should be a file name without
a path, it must reside in the same directory as the program.
ShowActivationMenu is a DWORD. When non-zero, determines that the Program
Activation menu should be shown. When zero, it will not be.
Signature is a REG_SZ containing the base 34 string representing the
digital signature that verifies the licensee. This setting may be overridden by
an entry in HKCU.
