goAES

Simple package for AES encryption and decryption. It use sha256 for hash the secret key. Based on CTR

Usage

Encryption

package main

import (
	"fmt"
	"log"

	goaes "github.com/syronz/goAES"
)

func main() {
	aes, err := goaes.New().Key("secret key").IV("iv is 16 char!!!").Build()
	if err != nil {
		log.Fatal(err)
	}

	term := "Hello"
	encrypted := aes.Encrypt(term)

	fmt.Printf("Encryption of %q is %q \n", term, encrypted)
}

output:

Encryption of "Hello" is "257d85d55b" 

Decryption

Default length is 100 character, in case the orginal term is more than 100 in AES decryption, you shold mention the Length in the build.

package main

import (
	"fmt"
	"log"

	goaes "github.com/syronz/goAES"
)

func main() {
	aes, err := goaes.New().Key("secret key").IV("iv is 16 char!!!").Build()
	if err != nil {
		log.Fatal(err)
	}

	encrypted := "257d85d55b"
	decrypted := aes.Decrypt(encrypted)

	fmt.Printf("Decryption of %q is %q \n", encrypted, decrypted)
}

output:

Decryption of "257d85d55b" is "Hello" 

Note

In case of the length of decrypted word is more than 100, we should use .Length(int) like here. Extra chars will be trimmed

aes, err := goaes.New().Key("secret key").IV("iv is 16 char!!!").Length(10000).Build()
