Types

type CryptoS

type CryptoS struct {
	// InputData is the data to be encrypted.
	InputData []byte

	// OutputData is the data encrypted.
	OutputData []byte

	// Key is the secret used for encrypted
	Key []byte

	// An initialization vector (IV) is an arbitrary number that can be used with a secret key for data encryption
	// to foil cyberattacks. This number, also called a nonce (number used once), is employed only one time in
	// any session to prevent unauthorized decryption of the message by a suspicious or malicious actor.
	IV []byte

	// Method is the encryption method such as AES.
	Method method.MethodType

	// Mode is the encrypted mode such as ECB.
	Mode mode.ModeType

	// Padding is the padding method such as PKCS7.
	Padding padding.PaddingType

	// Errors is the errors
	Errors error
}
