public static class GeneratorUtilities
Factory for symmetric key generators ( CipherKeyGenerator) and asymmetric key pair generators ( IAsymmetricCipherKeyPairGenerator), resolved by algorithm name or ASN.1 OID.
public static CipherKeyGenerator GetKeyGenerator(DerObjectIdentifier oid)

Resolve a CipherKeyGenerator for the given symmetric algorithm OID.

public static CipherKeyGenerator GetKeyGenerator(string algorithm)

Resolve a CipherKeyGenerator for the named symmetric algorithm (e.g. "AES", "DESede", "ChaCha20"), pre-configured with the algorithm's default key size.

public static IAsymmetricCipherKeyPairGenerator GetKeyPairGenerator(DerObjectIdentifier oid)

Resolve an IAsymmetricCipherKeyPairGenerator for the given algorithm OID.

public static IAsymmetricCipherKeyPairGenerator GetKeyPairGenerator(string algorithm)

Resolve an IAsymmetricCipherKeyPairGenerator for the named asymmetric algorithm (e.g. "RSA", "ECDSA", "Ed25519", "DH").
