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. C

#include <C_CkBinData.h>
#include <C_CkStringBuilder.h>

void ChilkatSample(void)
    {
    const char *byteVals;
    HCkBinData binData;
    HCkStringBuilder sb;

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

    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.
    binData = CkBinData_Create();
    CkBinData_AppendEncoded(binData,byteVals,"decList");

    // Examine the data in hex
    printf("HEX: %s\n",CkBinData_getEncoded(binData,"hex"));

    // Decode to a StringBuilder
    sb = CkStringBuilder_Create();
    CkStringBuilder_AppendBd(sb,binData,"us-ascii",0,0);

    // The bytes were actually the us-ascii char values for the string
    // "The true sign of intelligence is not knowledge but imagination."
    printf("%s\n",CkStringBuilder_getAsString(sb));

    // Now get the bytes in decimal list format again:
    printf("%s\n",CkBinData_getEncoded(binData,"decList"));

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