WebEvery value is encoded as a TLV triplet: [TAG, LENGTH, VALUE] For example you can check the GITHUB certificate here. On the right is the hexdump of the DER encoded certificate, on the left is its translation in ASN.1 format. As you can see, without the RFC near by we don't really know what each value corresponds to.

The ASN.1 DER format is deterministic; i.e. there is only a single sequence of bytes that validly encodes given r and s values. Mind the details, though: the encodings of r and s are minimal-sized signed big-endian. Since r and s are positive values, this means that the top bit of the first byte of each encoding must be zero. greenworks battery and charger set 60vhttp://encoders-decoders.online-domain-tools.com/ foamspray auto
