| Q: Your compiler supplies a der_encode() procedure. How do I encode BER? |
| 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, |
| simply use the DER encoder, der_encode(). |
