hi...
i'm a noob in openssl.. my employee asked me to edit our c++ cert
issuer engine developed using openssl. currently the cert generated
will be valid based on the time we generate it. for example, if i
generate a cert at 13 july 2007 1:30pm and set its validity for 5
days, the cert will be valid only till 18 july 2007 1:30 pm.. what
should I do to make the cert valid till 11:59pm on that day? This
is what my boss asked me to do.. please help.. any help is greatly
appreciated.
Cert signing routines generally set the not-before and not-after
times relative to "now". So you'll need to find a tie in seconds
that represents midnight of some day. Then find the difference from
that time to "now".
Do a UNIX "man mktime". It describes several routines that manipulate
a "tm" structure. Basically, you convert the current expire time to
a tm struct, set the day to what you want, set the hour, minute, and
second to maximum, and convert back to a time_t.
