	CTR = "CTR"
)

Functions

func DecryptKey

func DecryptKey(encryptedKey, key []byte, opts *Opts) ([]byte, error)

func EncryptKey

func EncryptKey(pri heimdall.Key, key []byte, opts *Opts) (encryptedKey []byte, err error)

Types

type Opts

type Opts struct {
	Algorithm string
	KeyLen    int
	OpMode    string
}

func NewOpts

func NewOpts(algorithm string, keyLen int, opMode string) (encOpt *Opts, err error)

func (*Opts) ToString

func (opt *Opts) ToString() string

ToString returns string format of encryption algorithm with key length (ex. AES128)
