(Objective-C) Example: Crypt2.GenRandomBytesENC methodShows how to use the GenRandomBytesENC method to generate a specified number of random bytes and return them as a binary encoded string, such as in base64 or hex format.
#import <CkoCrypt2.h> #import <NSString.h> CkoCrypt2 *crypt = [[CkoCrypt2 alloc] init]; // Example of a some of the binary encodings supported by Chilkat. // Internally uses the Fortuna cryptographically secure random number generation algorithm // auto-seeded from a secure source of entropy that depends on the OS. crypt.EncodingMode = @"hex"; NSString *s = [crypt GenRandomBytesENC: [NSNumber numberWithInt: 8]]; NSLog(@"%@%@",@"Uppercase Hex: ",s); crypt.EncodingMode = @"hex_lower"; s = [crypt GenRandomBytesENC: [NSNumber numberWithInt: 8]]; NSLog(@"%@%@",@"Lowercase Hex: ",s); crypt.EncodingMode = @"base64"; s = [crypt GenRandomBytesENC: [NSNumber numberWithInt: 8]]; NSLog(@"%@%@",@"Base64: ",s); crypt.EncodingMode = @"base64url"; s = [crypt GenRandomBytesENC: [NSNumber numberWithInt: 8]]; NSLog(@"%@%@",@"Base64Url: ",s); crypt.EncodingMode = @"base58"; s = [crypt GenRandomBytesENC: [NSNumber numberWithInt: 8]]; NSLog(@"%@%@",@"Base58: ",s); crypt.EncodingMode = @"base32"; s = [crypt GenRandomBytesENC: [NSNumber numberWithInt: 8]]; NSLog(@"%@%@",@"Base32: ",s); crypt.EncodingMode = @"decList"; s = [crypt GenRandomBytesENC: [NSNumber numberWithInt: 8]]; NSLog(@"%@%@",@"Decimal List: ",s); // Sample Output: // Uppercase Hex: 1BA0E87915C3B429 // Lowercase Hex: 1e1638a1c7996c58 // Base64: 1lV0I/su5lg= // Base64Url: Zq7DU0nukLk // Base58: foUVWUjAT6e // Base32: LHV5RV4HRCLW2=== // Decimal List: 168,55,214,82,93,154,191,164 |
