Encrypt secrets for the Adyen payment platform.

This library uses crypto/rand to generate cryptographically secure AES keys and nonces, and re-uses the same key and nonce for each client. Other publicly available libraries typically use math/rand which is insecure for generating secret keys and nonces.


package main

import (

func main() {
	// create new client with a specific site key.
	client, err := adyen.NewClient(os.Getenv("ADYEN_SITE_KEY"))
	if err != nil {
	// encrypt card number
	// if you need to encrypt multiple values into one string (for example, a map) you can use Encrypt.
	encrypted, err := client.EncryptSingle(adyen.Version118, "number", "5555555555554444", adyen.GenerationTimeNow)
	if err != nil {
	// print encrypted card number

type GenerationTimeFunc added in v1.1.4

type GenerationTimeFunc func(version string, value map[string]interface{}) time.Time

GenerationTimeFunc is a function responsible for returning the correct "generationtime" key given a version and value.

var GenerationTimeNow GenerationTimeFunc = func(version string, value map[string]interface{}) time.Time {
	return time.Now()

GenerationTimeNow returns time.Now as the generated time.
