# vinegar

vinegar is a library for producing, Vigenere tables and encrypting/decrypting

messages with them.

Plaintext messages have their spaces removed during encryption as the library

uses the standard latin alphabet modified by a keyword (with duplicates removed).

This means the decrypted message will also have no spaces but will match the

plaintext input in all other ways.

```go

package main

import (

    "fmt"

  

    "github.com/h5law/vinegar"

)

func main() {

    vig := vinegar.NewVigenere("kyrptos")

    cipher := vig.Encrypt("this is a secret hidden message", "neddih")

    plain := vig.Decrypt(cipher, "neddih")

    fmt.Println(cipher)                        // wzzjtqklunlzwzzqzzfpujuusv

    fmt.Println(plain)                         // thisisasecrethiddenmessage

    // Using the wrong key

    fmt.Println(vig.Decrypt(cipher, "hidden")) // cdisnyfrecsscdidhsxhesdrma

}

```
