Class C509SignatureAlgorithm

java.lang.Object
org.bouncycastle.cbor.c509.C509SignatureAlgorithm
public final class C509SignatureAlgorithm extends Object
The C509 Signature Algorithms Registry, Section 8.14 of draft-ietf-cose-cbor-encoded-cert-20. Each registered CBOR int value stands for a complete X.509 AlgorithmIdentifier, including its parameters, so conversion in either direction is an exact table lookup.

Note the draft's Figure 18 prints the DER for values 23-25 with an inconsistent SEQUENCE length octet (0x0B against 13 content octets); the entries here are built from the OID object model and encode with the correct 0x0D, matching real certificates and the value -256 row.
