Description John McBride 2001-10-08 03:03:38 EDT
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i586; en-US; rv:0.9.4) Gecko/20010917

Description of problem:
libcrypto.so does not define EVP_mdc2 although it is in the header file
evp.h. I have both openssl-0.9.6-9.i386.rpm and
openssl-devel-0.9.6-9.i386.rpm installed.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1)create foo.c :

#include "openssl/evp.h"

2)  gcc -o foo foo.c -L/usr/lib -lcrypto

Actual Results:  /tmp/ccQBIP0C.o: In function `main':
/tmp/ccQBIP0C.o(.text+0x7): undefined reference to `EVP_mdc2'
collect2: ld returned 1 exit status

Expected Results:  no link phase error.

Additional info:

1)create foo.c :

#include "openssl/evp.h"

2)  gcc -o foo foo.c -L/usr/lib -lcrypto

(this works)
Comment 1 Mark J. Cox 2001-11-23 11:01:01 EST
The version of OpenSSL shipped with Red Hat has serveral
patent-or-otherwise-encumbered code disabled.  This includes MDC-2, IDEA, and RC5.
(MDC-2 patent #4,908,861)
Comment 2 g.trentalancia 2009-11-17 16:42:08 EST
MDC-2 is no longer covered by patent (the patent has expired in 2002), see https://bugzilla.redhat.com/show_bug.cgi?id=538192.
