One Module of KeyManager which manages verified certificates for Validator.

The certificates inside the cache would have an expire time and there is a maximum life time for all certificates.

Certificates can be searched by key name and interest

const time::nanoseconds DEFAULT_LIFE_TIME(time::seconds(3600));

class CertificateCache
{
public:
  // @brief Create an object for certificate cache.

  ~CertificateCache();

  // @brief Insert certificate into cache.

  // @brief Get certificate given key name. The method will also remove outdated certificate entries.
