How do I encode BER? -A: +3.Q: Your compiler supplies a der_encode() procedure. How do I encode BER? +3.A: The DER (and CER) are stricter subsets of a more generic BER encoding method. If you encode data with DER or CER, all BER-conformant decoders will easily understand that. Hence, to encode data in the BER format,
