Types

type Cipher

type Cipher interface {
	// Encrypt encrypts the given plainBlob and returns the encrypted data.
	Encrypt(ctx context.Context, plainBlob []byte) ([]byte, error)
	// Decrypt decrypts the given encryptedBlob and returns the original data.
	Decrypt(ctx context.Context, encryptedBlob []byte) ([]byte, error)
}

Cipher provides methods for encrypting and decrypting byte slices.

type CipherText

type CipherText interface {
	Cipher
	// EncryptString encrypts the given plaintext string and returns the encrypted string.
	EncryptString(ctx context.Context, plaintext string) (string, error)
	// DecryptString decrypts the given encryptedString and returns the original string.
	DecryptString(ctx context.Context, encryptedString string) (string, error)
}

CipherText extends the Cipher interface with methods for encrypting and decrypting strings.

type Padder

type Padder interface {
	// Pad applies padding to the given plainData and returns the padded data.
	Pad(plainData []byte) []byte
	// UnPad removes padding from the given encryptedData and returns the unpadded data.
	UnPad(encryptedData []byte) []byte
}

Padder provides methods for adding and removing padding from byte slices.
