(Go) Calculate MD5 Hash of File (or SHA1, SHA256, and other hash algorithms)

Demonstrates how to calculate a hash for a file's contents.

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

    crypt := chilkat.NewCrypt2()

    // Set the name of the hash algorithm.
    // Other choices include "sha1", "sha256", "sha384", "sha512", "md2", "md5", and "haval". 
    crypt.SetHashAlgorithm("md5")

    // EncodingMode specifies the encoding of the hash output.
    // It may be "hex", "url", "base64", or "quoted-printable".
    crypt.SetEncodingMode("hex")

    // Files of any type may be hashed -- it doesn't matter
    // if the file is binary or text...
    var hashStr *string = new(string)
    hashStr = crypt.HashFileENC("/temp/something.dat")
    if crypt.LastMethodSuccess() != true {
        fmt.Println(crypt.LastErrorText())
        crypt.DisposeCrypt2()
        return
    }

    fmt.Println(*hashStr)

    crypt.DisposeCrypt2()
