Obj-c ile ile md5 ve sha1 yapmanın yolu..

Adım 1.

#import <CommonCrypto/CommonDigest.h>

Adım 2.

SHA1

-(NSString*) sha1:(NSString*)input
{
 const char *cstr = [input cStringUsingEncoding:NSUTF8StringEncoding];
 NSData *data = [NSData dataWithBytes:cstr length:input.length];
 
 uint8_t digest[CC_SHA1_DIGEST_LENGTH];
 
 CC_SHA1(data.bytes, data.length, digest);
 
 NSMutableString* output = [NSMutableString stringWithCapacity:CC_SHA1_DIGEST_LENGTH * 2];
 
 for(int i = 0; i < CC_SHA1_DIGEST_LENGTH; i++)
 [output appendFormat:@"%02x", digest[i]];
 
 return output;
 
}

MD5

- (NSString *) md5:(NSString *) input
{
 const char *cStr = [input UTF8String];
 unsigned char digest[16];
 CC_MD5( cStr, strlen(cStr), digest ); // This is the md5 call
 
 NSMutableString *output = [NSMutableString stringWithCapacity:CC_MD5_DIGEST_LENGTH * 2];
 
 for(int i = 0; i < CC_MD5_DIGEST_LENGTH; i++)
 [output appendFormat:@"%02x", digest[i]];
 
 return  output;
 
}
