Re: [PyQt] [SIP]MD5 openssl
Hello again,
In the case that somebody want to help me with that problem, I attached
some files.
import os
import sipconfig
# The name of the SIP build file generated by SIP and used by the build
# system.
build_file = md5test.sbf
# Get the SIP configuration information.
config = sipconfig.Configuration()
# Run SIP to generate the code.
os.system( .join([config.sip_bin, -c, ., -b, build_file, md5test.sip]))
# Create the Makefile.
makefile = sipconfig.SIPModuleMakefile(config, build_file)
# Add the library we are wrapping. The name doesn't include any platform
# specific prefixes or extensions (e.g. the lib prefix on UNIX, or the
# .dll extension on Windows).
makefile.extra_libs = [ssl]
makefile._build['objects'] += md5test.o
# Generate the Makefile itself.
makefile.generate()
#include openssl/md5.h
#include md5test.h
void md5test::hash()
{
unsigned char* hash;
unsigned char* md;
unsigned char* d;
unsigned long n = 1;
d = new unsigned char(1);
*d = 123;
hash = new unsigned char(16);
md = new unsigned char(16);
hash = MD5(d,n,md);
}
#include openssl/md5.h
class md5test {
public:
void hash();
};
%Module md5test
class md5test
{
%TypeHeaderCode
#include iostream
#include openssl/md5.h
#include md5test.h
%End
public:
void hash();
};
