func WriteKeyToPem ¶
WriteKeyToPem will convert SM4Key to PEM format data and return it.
Types ¶
type SM3 ¶
type SM3 struct {
// contains filtered or unexported fields
}
func (*SM3) BlockSize ¶
BlockSize returns the hash's underlying block size. The Write method must be able to accept any amount of data, but it may operate more efficiently if all writes are a multiple of the block size.
func (*SM3) Reset ¶
func (sm3 *SM3) Reset()
Reset clears the internal state by zeroing bytes in the state buffer. This can be skipped for a newly-created hash state; the default zero-allocated state is correct.
type SM4Key ¶
type SM4Key []byte
func ReadKeyFromPem ¶
ReadKeyFromPem will return SM4Key from PEM format data.
