Hash the Contents of a File (SHA256 and other hash algorithms)

See more Encryption Examples

Demonstrates how to hash the contents of a file using SHA256, SHA384, SHA512, MD2, MD5, HAVAL, RIPEMD, etc. Go

    // This example requires the Chilkat API to have been previously unlocked.
    // See Global Unlock Sample for sample code.

    crypt := chilkat.NewCrypt2()

    // Choose the hash algorithm.
    // Can be  "sha1", "sha256", "sha384", "sha512", "md2", "md5", "haval", "ripemd128", "ripemd160","ripemd256", or "ripemd320".
    crypt.SetHashAlgorithm("sha256")

    var hashBytes []byte
    hashBytes = crypt.HashFile("qa_data/jpg/starfish.jpg")

    // Let's examine the hash as a hex string.
    sb := chilkat.NewStringBuilder()
    sb.AppendEncoded(hashBytes,"hex")
    fmt.Println("SHA256 hash = ", *sb.GetAsString())

    crypt.DisposeCrypt2()
    sb.DisposeStringBuilder()
