Functions

bufEquals(ByteBuffer b1, ByteBuffer b2) → bool

bytesUnwrapDer(Uint8List derEncoded, Uint8List oid) → Uint8List

Extracts a payload from the given derEncoded data, and checks that it was tagged with the given oid.

bytesUnwrapDerSignature(Uint8List derEncoded) → Uint8List

ECDSA DER Signature 0x30|b1|0x02|b2|r|0x02|b3|s b1 = Length of remaining data b2 = Length of r b3 = Length of s

bytesWrapDer(Uint8List payload, Uint8List oid) → Uint8List

Wraps the given payload in a DER encoding tagged with the given encoded oid like so: SEQUENCE(oid, BITSTRING(payload))

bytesWrapDerSignature(Uint8List rawSignature) → Uint8List

decodeLenBytes(Uint8List buf, int offset) → int

encodeLen(Uint8List buf, int offset, int len) → int

encodeLenBytes(int len) → int

isDerPublicKey(Uint8List pub, Uint8List oid) → bool

isDerSignature(Uint8List sig) → bool
