Checksums

This example demonstrates how to use the crypt service to calculate checksums using various algorithms.

package main

import (
    "fmt"

    "github.com/Snider/Enchantrix/pkg/crypt"
)

func demoChecksums() {
    fmt.Println("--- Checksum Demo ---")
    cryptService := crypt.NewService()

    // Luhn
    luhnPayloadGood := "49927398716"
    luhnPayloadBad := "49927398717"
    fmt.Printf("Luhn Checksum:\n")
    fmt.Printf("  - Payload '%s' is valid: %v\n", luhnPayloadGood, cryptService.Luhn(luhnPayloadGood))
    fmt.Printf("  - Payload '%s' is valid: %v\n", luhnPayloadBad, cryptService.Luhn(luhnPayloadBad))

    // Fletcher
    fletcherPayload := "abcde"
    fmt.Printf("\nFletcher Checksums (Payload: \"%s\"):\n", fletcherPayload)
    fmt.Printf("  - Fletcher16: %d\n", cryptService.Fletcher16(fletcherPayload))
    fmt.Printf("  - Fletcher32: %d\n", cryptService.Fletcher32(fletcherPayload))
    fmt.Printf("  - Fletcher64: %d\n", cryptService.Fletcher64(fletcherPayload))
    fmt.Println()
}
