Detailed Description

represents a key

Key is at the second level in PIB's Identity-Key-Certificate hierarchy. An Key has a Name (identity + keyId), and contains one or more certificates, one of which is set as the default certificate of this key. A certificate can be directly accessed from a Key object.

Exceptions
PibImpl::Errorwhen underlying implementation has non-semantic error.

Definition at line 45 of file key.hpp.

Constructor & Destructor Documentation

◆ Key() [1/2]

ndn::security::Key::Key ( )

Default Constructor.

Key created using this default constructor is just a place holder. It must obtain an actual instance from Identity::getKey(...). A typical usage would be for exception handling:

Key key; try { key = Identity.getKey(...); } catch (Pib::Error&) { ... }

A Key instance created using the constructor is invalid. Calling a member method on an invalid Key instance may cause an std::domain_error.

Definition at line 29 of file key.cpp.

◆ Key() [2/2]

ndn::security::Key::Key ( const Name identityName,
const name::Component keyId,
shared_ptr< PibImpl impl 
)

Create an KeyEntry with identityName and keyId.

Parameters
identityNameThe name of the Identity.
keyIdThe key id of the key.
implThe actual backend implementation.
Exceptions
Pib::Errorif the key does not exist.

Definition at line 54 of file key.cpp.
