Hello Howard, hello OpenSSL developers,

Excellent resource, thanks. For the OpenSSL patches, you fixed some
longstanding bugs (I had been aware of the TRUE/FALSE constant strings
-which were misconverted in the EBCDIC version-, and I find your
solution to it elegant).

At
  http://www.openldap.org/faq/index.cgi?file=745
you print the set of patches to OpenSSL, and I verified them to work
on our BS2000 version of OpenSSL as well - the do indeed fix the problems
in the openssl application. One minor nit: in apps/ca.c, you subtract
the literal EBCDIC-'@' from an EBCDIC-char to construct the control-char;
this will not work, you must use 0x40 instead of '@' (fixed in
attached patch).

I vote for including the patch into mainstream OpenSSL. I repeat the
('@'-fixed) Howard Chu EBCDIC patch in this mail because the version
from http://www.openldap.org/faq/index.cgi?file=745 does not
apply cleanly (HTML-escapes present).

OpenSSL developers: this patch is against 0.9.6i, and is verified to
work for the IBM OS/390 and Fujitsu-Siemens BS2000(OSD/POSIX)
EBCDIC versions.

Thank you,

   Martin Kraemer
