typedef struct { ... } *SilcSILCPublicKey;

    This structure defines the SILC protocol style public key.  User
    doesn't have to access this structure usually, except when access to
    the identifier is required.  The silc_pkcs_get_context for the
    PKCS type SILC_PKCS_SILC returns this context.

    typedef struct SilcSILCPublicKeyStruct {
      SilcPublicKeyIdentifierStruct identifier;
      const SilcPKCSAlgorithm *pkcs;   /* PKCS algorithm */
      void *public_key;                /* PKCS algorithm specific public key */
    } *SilcSILCPublicKey;
