debugging https access under emacs/w3



Replying to my own mail ...

I mentioned  a while ago I was having trouble with https  pages.
Getting back to this the problem seems to be a change in the format
for the arguments of the s_client command of openssl.  
For my version
OpenSSL 0.9.7a Feb 19 2003
the synopsis line for the manual reads 
       openssl s_client [-connect host:port>] [-verify depth] [-cert file-
....
rather than the -host hostname -port port form I have seen in older
versions.  this needs a change in the ssl-program-arguments variable.
Mine is now set to
ssl-program-arguments's value is 
("s_client" "-quiet" "-connect" host ":" service "-verify"
 (int-to-string ssl-certificate-verification-policy)
 "-CApath ~/.certs")
This also doesn't work directly since it makes spaces around the colon
which openssl doesn't like.  So I hacked the  quietssl script to
remove the space. 
----------------------------------------------------------------------
#!/bin/sh
#redirect stderr so emacs doesn't barf on opensll
newargs=`echo "$@" |sed 's/ : /:/'`
exec 2>/dev/null
exec openssl $newargs
U70-
Clearly a better way to do this is within the variable definition
#itself, something like

("s_client" "-quiet" "-connect" (format "%s:%d" host service) "-verify"
 (int-to-string ssl-certificate-verification-policy)
 "-CApath ~/.certs")
but for some reason this doesn't work, almost certainly a trivial
 elisp misunderstanding on my part (would someone care to enlighten me).
I hope this is useful for anyone else with the same problem.
cheers
Peter
