xor Cipher Algorithm
With this logic, a string of text can be coded by using the bitwise XOR operator to every character use a given key. In cryptanalysis, the simple XOR cipher is a type of additive cipher, an encryption algorithm that operates according to the principles:
package main
import "fmt"
func encrypt(key int, plaintext []int)(ciphertext []int){
for _,char:= range plaintext {
ciphertext = append(ciphertext,xor(char,key))
}
return
}
func xor(char int,key int)int{
return (char^key)
}
func decrypt(key int, ciphertext []int)(plaintext []int){
for _,char:= range ciphertext {
plaintext = append(plaintext , xor(char,key))
}
return
}
func decodeToString(slice []int)(str string){
for _,v:= range slice{
str+=string(v)
}
return
}
func toASCII(slice []rune)[]int{
var converted []int
for _,v:= range slice{
converted = append(converted, int(v))
}
return converted
}
func main(){
str := "hello world"
key :=97
temp:= []rune(str)
message:=toASCII(temp)
encrypted:=encrypt(key,message)
decrypted:=decrypt(key,encrypted)
plaintext:=decodeToString(decrypted)
fmt.Println(plaintext)
}
