Functions

func Decrypt

func Decrypt(ciphertextBase64 string, key []byte, encryptMethod Type) ([]byte, error)

Decrypt decrypts ciphertext using the specified encryption method with the given key.

func Encrypt

func Encrypt(plaintext, key []byte, encryptMethod Type) (string, error)

Encrypt encrypts plaintext using the specified encryption method with the given key and IV.

func PKCS7Padding

func PKCS7Padding(data []byte, blockSize int) []byte

PKCS7Padding adds padding to the plaintext to make it a multiple of the block size.

func PKCS7Unpadding

func PKCS7Unpadding(data []byte) []byte

PKCS7Unpadding removes padding from the plaintext.

Types

type Container

type Container map[string]Encrypter

Container is the container for the encrypter.

func NewContainerFromConfig

func NewContainerFromConfig(str store.Store, conf config.ValidEncryptConfig) (Container, error)

NewContainerFromConfig creates a new encrypter container.

type DynamicEncrypter

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

DynamicEncrypter is the dynamic encrypter.

func NewDynamicEncrypter

func NewDynamicEncrypter(
	str store.Store,
	storeBucketID,
	storeKey string,
	method Type,
) (*DynamicEncrypter, error)

NewDynamicEncrypter creates a new dynamic encrypter.

func (*DynamicEncrypter) Decrypt

func (e *DynamicEncrypter) Decrypt(ciphertextBase64 string) ([]byte, error)

Decrypt decrypts the ciphertext using the dynamic encrypter.

func (*DynamicEncrypter) Encrypt

func (e *DynamicEncrypter) Encrypt(plaintext []byte) (string, error)
