Types

type AES

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

AES provides encryption and decryption using the AES-GCM mode.

func NewAES

func NewAES(key []byte) (*AES, error)

NewAES creates a new AES instance with the provided key. The key must be one of the following lengths: 16, 24, or 32 bytes, corresponding to AES-128, AES-192, and AES-256, respectively.

func (*AES) Decrypt

func (a *AES) Decrypt(_ context.Context, ciphertext []byte) ([]byte, error)

Decrypt decrypts the given ciphertext using AES-GCM. The context parameter is ignored but is included for interface compliance. The ciphertext must include the nonce as its prefix.

func (*AES) Encrypt

func (a *AES) Encrypt(_ context.Context, plaintext []byte) ([]byte, error)

Encrypt encrypts the given plaintext using AES-GCM. The context parameter is ignored but is included for interface compliance. The resulting ciphertext includes the nonce prepended to the encrypted data.

type Encrypter

type Encrypter interface {
	// Encrypt returns the encrypted ciphertext.
	Encrypt(ctx context.Context, plaintext []byte) ([]byte, error)
	// Decrypt returns the decrypted plaintext.
	Decrypt(ctx context.Context, ciphertext []byte) ([]byte, error)
}

Encrypter defines an interface for encryption and decryption mechanisms. Implementations of this interface must support securely encrypting plaintext and decrypting ciphertext, optionally considering context for cancellation or deadlines.
