Learning Functional Programming in Go

Imports

We have more imports. We'll use go_utils for its Dashes function to anonymize the credit card number. Also, we'll import a number of crypto packages for decrypting the credit card number:

package main

import (
       "log"
       "fmt"
       gc "github.com/go-goodies/go_currency"
       gu "github.com/go-goodies/go_utils"
       "strings"
       "crypto/aes"
       "crypto/cipher"
       "crypto/rand"
       "encoding/base64"
       "errors"
       "io"
       "bytes"
