Functions

func Encode

func Encode(r Result) []byte

Encode serializes a Result back to DER for testing/interop.

func EncodeIdentity

func EncodeIdentity(t int32, data []byte) []byte

EncodeIdentity serializes the pair (int32, []byte)

Types

type Result

type Result struct {
	IsInt bool
	Int32 int32  // valid when IsInt == true
	Str   string // valid when IsInt == false
	Data  []byte // zero-copy reference into input
}

Result holds the decoded payload. IsInt distinguishes the two variants. Data is a zero-copy sub-slice of the input — do not modify input while using it.

func DecodeIdentity

func DecodeIdentity(b []byte) (Result, error)

DecodeIdentity parses a DER SEQUENCE containing either [INTEGER, OCTET STRING] or [UTF8String, OCTET STRING].
