iphone - NSMutableData convert to NSString -


why data not similar objnsdata? 

nsstring *strdata = @"bonjour tout le monde, je voudrais vous présenter la société fdfdfdf  futur"; nsmutabledata *objnsdata = [nsmutabledata datawithdata:[strdata datausingencoding:nsutf8stringencoding]];  objnsdata = [objnsdata encryptaes:@"samplekey"];   nslog(@"objnsdata%@", objnsdata);  nsstring *str=[[nsstring alloc] initwithdata: objnsdata encoding:nsutf8stringencoding];  nslog(@"str%@",str);  nsmutabledata *data = [[nsmutabledata alloc] initwithdata:[ str datausingencoding:nsutf8stringencoding]];  nslog(@"data%@",data);

you seem storing nsdata representation of string, encrypting , hoping converting give same thing started out with.

while i'm not entirely sure why you're trying encrypt nsdata instance, if want convert nsstring want decrypt on way back.
