Functions

func GenerateKey 

func GenerateKey() ([]byte, error)

GenerateKey generates a random 32-byte encryption key suitable for AES-256 This is a helper function for initial setup, not for production use

func GenerateKeyBase64 

func GenerateKeyBase64() (string, error)

GenerateKeyBase64 generates a random 32-byte key and returns it base64-encoded

Types

type Service 

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

Service provides AES-256-GCM encryption/decryption for sensitive data

func NewService 

func NewService(key []byte) (*Service, error)

NewService creates a new encryption service with the provided 32-byte key

func NewServiceFromBase64 

func NewServiceFromBase64(encodedKey string) (*Service, error)

NewServiceFromBase64 creates a new encryption service from a base64-encoded key

func (*Service) Decrypt 

func (s *Service) Decrypt(encodedCiphertext string) (string, error)

Decrypt decrypts base64-encoded ciphertext using AES-256-GCM

func (*Service) Encrypt 

func (s *Service) Encrypt(plaintext string) (string, error)

Encrypt encrypts plaintext using AES-256-GCM and returns base64-encoded ciphertext Format: base64(nonce + ciphertext + tag)
