Detailed Description

Abstraction of private key in crypto transformation.

Definition at line 38 of file private-key.hpp.

Member Typedef Documentation

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

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 59 of file private-key.hpp.

Constructor & Destructor Documentation

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

Create an empty private key instance.

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

Definition at line 80 of file private-key.cpp.

ndn::security::transform::PrivateKey::~PrivateKey ( )
default

Member Function Documentation
