UU Encoding and Decoding

See more Encryption Examples

Demonstrates how to UU encode and decode. Objective-C

#import <CkoCrypt2.h>
#import <NSString.h>

//  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 = 0;
NSString *s2 = 0;
NSString *s3 = 0;

s1 = @"This string is to be UU encoded";

crypt.UuMode = @"666";
crypt.UuFilename = @"something.txt";

//  UU encode:
s2 = [crypt EncodeString: s1 charset: @"ansi" encoding: @"uu"];

//  Note: Call crypt.Encode instead of crypt.EncodeString
//  to UU encode binary bytes (i.e. non-text binary data).

NSLog(@"%@",s2);

//  UU decode:
CkoCrypt2 *crypt2 = [[CkoCrypt2 alloc] init];
s3 = [crypt2 DecodeString: s2 charset: @"ansi" encoding: @"uu"];

//  Note: Likewise, call crypt.Decode to decode non-text binary data.

NSLog(@"%@",s3);

//  Show the file permissions mode and filename found
//  in the UU encoded data:
NSLog(@"%@%@",@"UuMode = ",crypt2.UuMode);
NSLog(@"%@%@",@"UuFilename = ",crypt2.UuFilename);
