This sample program demonstrates how to Digest-MD5 hash a string and encode the result as a URL-encoded string.

// The Chilkat Encryption library is also available as an ActiveX component
// or .NET class with the identical set of methods and properties.

// Digest-MD5 hash to a URL-encode a string.
void CryptExample(void)
    {
    CkCrypt2 crypt;
    
    // Any string passed to UnlockComponent automatically begins the 30-day trial.
    crypt.UnlockComponent("30-day trial");

    // Use the Digest-MD5 hash algorithm.
    // Other hash algorithms: haval, md2, sha-1 (sha-256), sha-384,sha-512
    crypt.put_HashAlgorithm("md5");
    
    // Set the output string encoding to "URL"
    // Other encoding modes: base64, hex, quoted-printable
    crypt.put_EncodingMode("url");

    CkString strHash;
    crypt.HashStringENC("Hash this string",strHash);

    printf("URL-encoded hash string: %s\n",strHash.getString());

    // PRINTS:
    // URL-encoded hash string: 7f0E%90%92%D7h%2C%2A%2Et%5Dt%AAk
