Types

type Utils

type Utils struct {
	// contains filtered or unexported fields
}

Utils is a utility structure that holds the AES key.

func NewUtils

func NewUtils() (*Utils, error)

NewUtils creates a new Utils instance with the AES key from the environment variable. The AES key must be exactly 32 bytes (256 bits) long.

func (*Utils) Decrypt

func (u *Utils) Decrypt(data string) ([]byte, error)

Decrypt decrypts the given base64 encoded data using AES encryption in CTR mode. The IV is extracted from the ciphertext and used to initialize the cipher.

func (*Utils) Encrypt

func (u *Utils) Encrypt(data []byte) (string, error)

Encrypt encrypts the given data using AES encryption in CTR mode. A random Initialization Vector (IV) is generated for each encryption operation. The IV is prepended to the ciphertext and base64 encoded.
