I have the following NSString category
@implementation NSString (NSStringJsonExtension)
- (NSString *)md5
{
#ifdef __APPLE__
const char *cStr = [self UTF8String];
unsigned char result[CC_MD5_DIGEST_LENGTH];
CC_MD5( cStr, (int)strlen(cStr), result ); // This is the md5 call
return [NSString stringWithFormat:
@"%02x%02x%02x%02x%02x%02x%02x%02x%02x%02x%02x%02x%02x%02x%02x%02x",
result[0], result[1], result[2], result[3],
result[4], result[5], result[6], result[7],
result[8], result[9], result[10], result[11],
result[12], result[13], result[14], result[15]
];
#else
NSLog(@"md5 not yet supported on GNUstep. Please implement");
return nil;
#endif
}
@end
working on MacOSX (neede to access HkVision cameras).
I would like to port this app to GNUstep and therefore need code that builds on Ubuntu (current GNUstep tree). The above code gives
SRHTTPRequest.m:93:27: error: 'CC_MD5_DIGEST_LENGTH' undeclared (first use in this function)
unsigned char result[CC_MD5_DIGEST_LENGTH];
^
SRHTTPRequest.m:93:27: note: each undeclared identifier is reported only once for each function it appears in
SRHTTPRequest.m:94:6: warning: implicit declaration of function 'CC_MD5' [-Wimplicit-function-declaration]
CC_MD5( cStr, (int)strlen(cStr), result ); // This is the md5 call
^
Any idea how to do md5 hashing on Linux/GNUstep?
Thanks a lot in advance!
