Types

type AES

type AES struct {
	AdditionalData []byte

	FixedNonce []byte
	// contains filtered or unexported fields
}

func NewAES

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

func (*AES) Decrypt

func (x *AES) Decrypt(ciphertext any) (any, error)

func (*AES) DecryptWithBytes

func (x *AES) DecryptWithBytes(cipherBuf []byte) ([]byte, error)

func (*AES) DecryptWithString

func (x *AES) DecryptWithString(ciphertext string) (string, error)

func (*AES) Encrypt

func (x *AES) Encrypt(plaintext any) (any, error)

func (*AES) EncryptWithBytes

func (x *AES) EncryptWithBytes(plaintext []byte) ([]byte, error)

func (*AES) EncryptWithString

func (x *AES) EncryptWithString(plaintext string) (string, error)

func (*AES) NewNonce

func (x *AES) NewNonce() []byte

func (*AES) NewNonceStr

func (x *AES) NewNonceStr() string

type HexEncoder

type HexEncoder struct{}

func (HexEncoder) DecodeString

func (h HexEncoder) DecodeString(s string) ([]byte, error)

func (HexEncoder) EncodeToString

func (h HexEncoder) EncodeToString(b []byte) string

type OptFunc

type OptFunc func(c *AES)

func AESOptWithDataByte

func AESOptWithDataByte(data []byte) OptFunc

func AESOptWithEncoder

func AESOptWithEncoder(i encoder) OptFunc

func AESOptWithFixedNonce

func AESOptWithFixedNonce(nonce []byte) OptFunc

AESOptWithFixedNonce sets the fixed nonce for the AES encryption. This setting enables the same string to be encrypted with the same result. This is needed in some business scenarios. However, it should be used with caution as it can lead to security vulnerabilities. If not sets this option will generate a new nonce for each encryption.

func AESOptWithNonceSize

func AESOptWithNonceSize(size int) OptFunc

AESOptWithNonceSize sets the nonce size for the AES encryption. The default nonce size is 12 bytes, which is the recommended size. If you need to use a different nonce size, you can set it using this option. NOTE: If you set a fixed nonce, this setting will be invalid.

type RSA

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