Decimal Integer List Encoding

See more Encryption Examples

The "decList" encoding was added in Chilkat v9.5.0.66 to encode and decode binary bytes from comma-separated decimal integers. Objective-C

#import <NSString.h>
#import <CkoBinData.h>
#import <CkoStringBuilder.h>

//  Note: This example requires Chilkat v9.5.0.66 or greater.

NSString *byteVals = @"84,104,101,32,116,114,117,101,32,115,105,103,110,32,111,102,32,105,110,116,101,108,108,105,103,101,110,99,101,32,105,115,32,110,111,116,32,107,110,111,119,108,101,100,103,101,32,98,117,116,32,105,109,97,103,105,110,97,116,105,111,110,46";

//  Demonstrate encoding/decoding comma-separated decimal integrs to/from binary.
CkoBinData *binData = [[CkoBinData alloc] init];
[binData AppendEncoded: byteVals encoding: @"decList"];

//  Examine the data in hex
NSLog(@"%@%@",@"HEX: ",[binData GetEncoded: @"hex"]);

//  Decode to a StringBuilder
CkoStringBuilder *sb = [[CkoStringBuilder alloc] init];
[sb AppendBd: binData charset: @"us-ascii" offset: [NSNumber numberWithInt: 0] numBytes: [NSNumber numberWithInt: 0]];

//  The bytes were actually the us-ascii char values for the string
//  "The true sign of intelligence is not knowledge but imagination."
NSLog(@"%@",[sb GetAsString]);

//  Now get the bytes in decimal list format again:
NSLog(@"%@",[binData GetEncoded: @"decList"]);

//  The output of this example is:
//  HEX: 5468652074727565207369676E206F6620696E74656C6C6967656E6365206973206E6F74206B6E6F776C656467652062757420696D6167696E6174696F6E2E
