Im using this framework to create an encrypted key then save into a file. The problem is not when I crypt,but when I decrypt. I get this error: EVP_DecryptFinal() failed! I use two selectors:

-(IBAction )generate:(id)sender{ NSString *password = [[tocrypt textStorage] string]; [crypto setClearTextWithString:password]; NSData *cipherText = [crypto encrypt:@"blowfish"]; [cipherText writeToFile:@"/Users/XYZ/Desktop/key.andrk" atomically:YES]; NSLog(@"Now encrypted: %s",[cipherText bytes]); }

-(IBAction )loadKey:(id)sender{ NSOpenPanel *oPanel = [[NSOpenPanel openPanel] retain]; [oPanel setTitle:@"Select a key file"]; [oPanel setPrompt:@"Choose"]; [oPanel setCanChooseDirectories:NO]; [oPanel setCanChooseFiles:YES]; [oPanel setAllowsMultipleSelection:NO]; [oPanel setResolvesAliases:NO]; if ([oPanel runModalForTypes: [NSArray arrayWithObjects: @"andrk", nil]] == NSOKButton) { NSArray *filesToOpen = [oPanel filenames]; NSString *aFile = [filesToOpen objectAtIndex:0]; NSData *onfly = [NSData dataWithContentsOfFile:aFile]; [crypto setCipherText:onfly]; NSData *decryptedTextData = [crypto decrypt:@"blowfish"]; [crypto release]; } }

if I save the crypt string as NSData, then I reload it and set it again as setCipherText:onfly, why it deosnt works? It seems ots nott feed right with the external NSData. tnx

who is using this framework? I need a small hand to solve a small problem.
How about posting the actual problem you're having?
