2017-08-22This has been added to avoid the situation where some host ctype.h functionsPauli
return true for characters > 127. I.e. they are allowing extended ASCII characters through which then cause problems. E.g. marking superscript '2' as a number then causes the common (ch - '0') conversion to number to fail miserably. Likewise letters with diacritical marks can also cause problems. If a non-ASCII character set is being used (currently only EBCDIC), it is adjusted for. The implementation uses a single table with a bit for each of the defined classes. These functions accept an int argument and fail for values out of range or for characters outside of the ASCII set. They will work for both signed and unsigned character inputs.

2017-07-24Add asn1_time_to_tm function and check days in monthPaul Yang
Based on discussion in PR #3566. Reduce duplicated code in original asn1_utctime_to_tm and asn1_generalizedtime_to_tm, and introduce a new internal function asn1_time_to_tm. This function also checks if the days in the input time string is valid or not for the corresponding month. Test cases are also added.

Also fix the undefined behaviour `*(long *)x = y` when x isn't a long or character pointer. ISO/IEC 9899:1999 6.5/7 for the details.

2017-05-02Fix time offset calculation.Todd Short
ASN1_GENERALIZEDTIME and ASN1_UTCTIME may be specified using offsets, even though that's not supported within certificates. To convert the offset time back to GMT, the offsets are supposed to be subtracted, not added. e.g. 1759-0500 == 2359+0100 == 2259Z.

1999-01-17Time to blow up the source tree :-) This is the beginning of support forDr. Stephen Henson
GeneralizedTime. At several points PKIX specifies that GeneralizedTime can be used but OpenSSL doesn't currently support it. This patch adds several files and a bunch of functions. Of interest is the ASN1_TIME structure and its related functions. At several points certificates, CRLs et al specify that a time can be expressed as a choice of UTCTime and GeneralizedTime. Currently OpenSSL interprets this (wrongly) as UTCTime because GeneralizedTime isn't supported. The ASN1_TIME stuff provides this functionality. Still todo is to trace which cert and CRL points need an ASN1_TIME and modify the utilities appropriately and of course fix all the bugs. Note new OpenSSL copyright in the new file a_time.c. I didn't put it in a_gentm.c because it is a minimally modified form a_utctm.c . Since this adds new files and error codes you will need to do a 'make errors' at the top level to add the new codes.
