Class C509PublicKeyAlgorithm

java.lang.Object
org.bouncycastle.cbor.c509.C509PublicKeyAlgorithm
public final class C509PublicKeyAlgorithm extends Object
The C509 Public Key Algorithms Registry, Section 8.15 of draft-ietf-cose-cbor-encoded-cert-20. Each registered CBOR int value stands for a complete X.509 AlgorithmIdentifier, including its parameters (for the elliptic curve entries the named curve is part of the parameters), so conversion in either direction is an exact table lookup.
