4.2.5 Doing things one usually don't want to do.
--extra-digest-algo name- Sometimes signatures are broken in that they announce a different digest
algorithm than actually used. gpgsm uses a one-pass data
processing model and thus needs to rely on the announcde digest
algorithms to properly hash the data. As a workaround this option may
be used to tell gpg to also hash the data using the algorithm
name; this slows processing down a little bit but allows to verify
such broken signatures. If gpgsm prints an error like
“digest algo 8 has not been enabled” you may want to try this option,
with ‘SHA256’ for name.
--faked-system-time epoch- This option is only useful for testing; it sets the system time back or
forth to epoch which is the number of seconds elapsed since the year
1970. Alternativly epoch may be given as a full ISO time string
(e.g. "20070924T154812").
--with-ephemeral-keys- Include ephemeral flagged keys in the output of key listings.
--debug-level level- Select the debug level for investigating problems. level may be
one of:
none- no debugging at all.
basic- some basic debug messages
advanced- more verbose debug messages
expert- even more detailed messages
guru- all of the debug messages you can get
How these messages are mapped to the actual debugging flags is not
specified and may change with newer releases of this program. They are
however carefully selected to best aid in debugging.
--debug flags- This option is only useful for debugging and the behaviour may change
at any time without notice; using
--debug-levels is the
preferred method to select the debug verbosity. FLAGS are bit encoded
and may be given in usual C-Syntax. The currently defined bits are:
0 (1)- X.509 or OpenPGP protocol related data
1 (2)- values of big number integers
2 (4)- low level crypto operations
5 (32)- memory allocation
6 (64)- caching
7 (128)- show memory statistics.
9 (512)- write hashed data to files named
dbgmd-000*
10 (1024)- trace Assuan protocol
Note, that all flags set using this option may get overriden by
--debug-level.
--debug-all- Same as
--debug=0xffffffff
--debug-allow-core-dump- Usually gpgsm tries to avoid dumping core by well written code and by
disabling core dumps for security reasons. However, bugs are pretty
durable beasts and to squash them it is sometimes useful to have a core
dump. This option enables core dumps unless the Bad Thing happened
before the option parsing.
--debug-no-chain-validation- This is actually not a debugging option but only useful as such. It
lets gpgsm bypass all certificate chain validation checks.
--debug-ignore-expiration- This is actually not a debugging option but only useful as such. It
lets gpgsm ignore all notAfter dates, this is used by the regresssion
tests.
--fixed-passphrase string- Supply the passphrase string to the gpg-protect-tool. This
option is only useful for the regression tests included with this
package and may be revised or removed at any time without notice.
--no-common-certs-import- Suppress the import of common certificates on keybox creation.
All the long options may also be given in the configuration file after
stripping off the two leading dashes.
