    // Hashing algorithms (i.e. digest algorithms) operate on raw bytes.
    // Therefore, we must specify the character encoding (utf-8, utf-16, iso-8859-1, etc.) to be used when hashing.

    // Get the SHA256 hash in hex
    var sha256_hex: String? = sb.GetHash("sha256", encoding: "hex", charset: "utf-8")
    print("SHA256: \(sha256_hex!)")

    // Get the SHA384 hash in hex lowercase
    var sha384_hex: String? = sb.GetHash("sha384", encoding: "hex_lower", charset: "utf-8")
    print("SHA384: \(sha384_hex!)")

    // Get the SHA512 hash in base64
    var sha512_base64: String? = sb.GetHash("sha512", encoding: "base64", charset: "utf-8")
    print("SHA512: \(sha512_base64!)")

    // Get the SHA1 hash in hex lowercase
    var sha1_hex: String? = sb.GetHash("sha1", encoding: "hex_lower", charset: "utf-8")
    print("SHA1: \(sha1_hex!)")

    // Get the CRC8 digest in decimal
    var crc8_decimal: String? = sb.GetHash("crc8", encoding: "decimal", charset: "utf-8")
    print("CRC8: \(crc8_decimal!)")
