This sample program demonstrates how to SHA-1 hash a byte array.

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

// SHA-1 Hash Byte Array
void CryptExample(void)
    {
    CkCrypt2 crypt;
    
    // Any string passed to UnlockComponent automatically begins the 30-day trial.
    crypt.UnlockComponent("30-day trial");

    // Use the SHA-1 hash algorithm.
    // Other hash algorithms: md5, md2, sha-1 (sha-256), sha-384, sha-512
    crypt.put_HashAlgorithm("sha1");
    
    // Create some data to hash.
    int i;
    unsigned char dataToHash[50];
    for (i=0; i<50; i++) dataToHash[i] = i;

    // Hash the byte array
    CkByteData hash;
    CkByteData inData;
    // Borrow the data so we don't need an extra memcpy
    inData.borrowData(dataToHash,50);
    crypt.HashBytes(inData,hash);

    printf("hash size = %d bytes\n",hash.getSize());

    // Display the hash.
    CkString strTemp;
    strTemp.appendHexData(hash.getData(),hash.getSize());
    printf("%s\n",strTemp.getString());

    // PRINTS:
    // hash size = 20 bytes
