Finish removing RIPEMD160 support, which was started in 2a285b75a1
. As
noted in that commit, FIPS 140-2 will abort if it's enabled. It's been
deprecated by OpenSSL as well.

|
|
*
|
|
* New capinfos features
|
|
*
|
|
* Continue processing additional files after
|
|
* a wiretap open failure. The new -C option
|
|
* reverts to capinfos' original behavior which
|
|
* is to cancel any further file processing at
|
|
* first file open failure.
|
|
*
|
|
* Change the behavior of how the default display
|
|
* of all infos is initiated. This gets rid of a
|
|
* special post getopt() argument count test.
|
|
*
|
|
* Add new table output format (with related options)
|
|
* This feature allows outputting the various infos
|
|
* into a tab delimited text file, or to a comma
|
|
* separated variables file (*.csv) instead of the
|
|
* original "long" format.
|
|
*
|
|
* 2011-04-05: wmeier
|
|
* behaviour changed: Upon exit capinfos will return
|
|
* an error status if an error occurred at any
|
|
* point during "continuous" file processing.
|
|
* (Previously a success status was always
|
|
* returned if the -C option was not used).

|
|
*
|
|
* A 64-bit Unix time would be safe for the indefinite future, as
|
|
* this variable would not overflow until 2**63 or
|
|
* 9,223,372,036,854,775,808 (over nine quintillion) seconds
|
|
* after the beginning of the Unix epoch - corresponding to
|
|
* GMT 15:30:08, Sunday, 4th December, 292,277,026,596.
|
|
*
|
|
* So, if we're displaying the time as YYYY-MM-DD HH:MM:SS.SSSSSSSSS,
|
|
* we'll have the buffer be large enouth for a date of the format
|
|
* 292277026596-MM-DD HH:MM:SS.SSSSSSSSS, which is the biggest value
|
|
* you'll get with a 64-bit time_t and a nanosecond-resolution
|
|
* fraction-of-a-second.
|
|
*
|
|
* That's 12+1+2+1+2+1+2+1+2+2+2+1+9+1, including the terminating
|
|
* \0, or 39.
|
|
*
|
|
* If we're displaying the time as epoch time, and the time is
|
|
* unsigned, 2^64-1 is 18446744073709551615, so the buffer has
|
|
* to be big enough for 18446744073709551615.999999999. That's
|
|
* 20+1+9+1, including the terminating '\0', or 31. If it's
|
|
* signed, 2^63 is 9223372036854775808, so the buffer has to
|
|
* be big enough for -9223372036854775808.999999999, which is
|
|
* again 20+1+9+1, or 31.
|
|
*
|
|
* So we go with 39.
