Types ¶
type BlockCipherEncoder ¶
type BlockCipherEncoder struct {
// contains filtered or unexported fields
}
BlockCipherEncoder can encode or decode data using a block cipher into a domain name
func NewBlockCipherEncoder ¶
func NewBlockCipherEncoder(domainName *pkg.DomainName, block cipher.Block) *BlockCipherEncoder
NewBlockCipherEncoder creates a new BlockCipherEncoder
func (*BlockCipherEncoder) Decode ¶
func (be *BlockCipherEncoder) Decode(src []byte) ([]byte, error)
Decode takes a domain name which contains a message encoded using a block cipher
func (*BlockCipherEncoder) Encode ¶
func (be *BlockCipherEncoder) Encode(src []byte) (string, error)
Encode encodes data into a domain name using a block cipher
func (*BlockCipherEncoder) MaxBytes ¶
func (be *BlockCipherEncoder) MaxBytes() int
MaxBytes is the maximum number of bytes that can be encoded into a single domain name taking the cipher block size and base domain name into account
