Functions ¶
func NewCipher ¶ added in v1.0.2060
NewCipher creates and returns a new cipher.Block. data bytes use BigEndian
func NewCipher1024 ¶ added in v1.0.2060
NewCipher1024 creates a new Threefish cipher with a block size of 1024 bits. The key argument must be 64 bytes and the tweak argument must be 16 bytes.
func NewCipher256 ¶ added in v1.0.2060
NewCipher256 creates a new Threefish cipher with a block size of 256 bits. The key argument must be 32 bytes and the tweak argument must be 16 bytes.
func NewCipher512 ¶ added in v1.0.2060
NewCipher512 creates a new Threefish cipher with a block size of 512 bits. The key argument must be 64 bytes and the tweak argument must be 16 bytes.
Types ¶
type KeySizeError ¶
type KeySizeError int
A KeySizeError is returned when the provided key isn't the correct size.
type TweakSizeError ¶
type TweakSizeError struct{}
A TweakSizeError is returned when the provided tweak isn't the correct size.
func (TweakSizeError) Error ¶
func (e TweakSizeError) Error() string
Error describes a TweakSizeError.
