Goravel's encryption services provide a simple, convenient interface for encrypting and decrypting text via OpenSSL using AES-256 encryption. All of Goravel's encrypted values are signed using a message authentication code (GMAC) so that their underlying value can not be modified or tampered with once encrypted.


Before using Goravel's encrypter, you must set the key configuration option in your config/app.go configuration file. This configuration value is driven by the APP_KEY environment variable. You should use the go run . artisan key:generate command to generate this variable's value since the key:generate command will use Golang's secure random bytes generator to build a cryptographically secure key for your application.

Using The Encrypter

Encrypting A Value

You may encrypt a value using the EncryptString method provided by the facades.Crypt. All encrypted values are encrypted using OpenSSL and the AES-256-GCM cipher. Furthermore, all encrypted values are signed with a message authentication code (GMAC). The integrated message authentication code will prevent the decryption of any values that have been tampered with by malicious users:

secret, err := facades.Crypt.EncryptString("goravel")

Decrypting A Value

You may decrypt values using the DecryptString method provided by the facades.Crypt. If the value can not be properly decrypted, such as when the message authentication code is invalid, an error will be return:

str, err := facades.Crypt.DecryptString(secret)
