Member Typedef Documentation

◆ PasswordCallback

using ndn::security::transform::PrivateKey::PasswordCallback = std::function<int(char* buf, size_t bufSize, bool shouldConfirm)>

Callback for application to handle password input.

The password must be written to buf and must not be longer than bufSize chars. It is recommended to ask the user to verify the password if shouldConfirm is true, e.g., by prompting for it twice. The callback must return the number of characters in the password or 0 if an error occurred.

Definition at line 55 of file private-key.hpp.

Constructor & Destructor Documentation

◆ PrivateKey()

ndn::security::transform::PrivateKey::PrivateKey ( )

Creates an empty private key instance.

One must call loadXXXX(...) to load a private key.
