// This example assumes the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

CkoCrypt2 *crypt = [[CkoCrypt2 alloc] init];

NSString *s1 = @"This is a test / = abc 123";

// The ReEncode method converts a string from one encoding
// to another.
// Valid encodings are "url", "base64", "qp", "hex", "ansi", "modbase64", "base64url", "base32", "base58",
// and any of the encodings listed here:  http://cknotes.com/chilkat-binary-encoding-list

// Use "ansi" for an unencoded ANSI string.

// Encode to URL-encoding:
NSString *s2 = [crypt ReEncode: s1 fromEncoding: @"ansi" toEncoding: @"url"];
NSLog(@"%@",s2);

// Convert from URL-encoding to base64:
NSString *b64 = 0;
b64 = [crypt ReEncode: s2 fromEncoding: @"url" toEncoding: @"base64"];
NSLog(@"%@",b64);

// Convert from base64 to hex:
NSString *hex = 0;
hex = [crypt ReEncode: b64 fromEncoding: @"base64" toEncoding: @"hex"];
NSLog(@"%@",hex);
