Hi,
I'm trying to get a MD5 Checksum of a file. This is my code:
______________________________
#import <CommonCrypto/CommonDigest.h>
- (NSString*)getMD5ChecksumOfFile:(NSString*)pathOfFile {
const char *cStr = [[NSData dataWithContentsOfFile:pathOfFile] bytes];
unsigned char result[CC_MD5_DIGEST_LENGTH];
CC_MD5(cStr, strlen(cStr), result);
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]];
__________________________
When I try to checksum a file I get a different checksum, than on the
command line using MD5.
My result: D41D8CD98F00B204E9800998ECF8427E
command line result ("md5 test.txt"): a3801c714957c21382d7fe07e0b29aa8
Can anybody tell me, why my code might be wrong. Or am I just doing
something wrong, when verifying my result against the command line
result?
Thankyou,
Sebastian.
