◆ setTpmPassword()

void ndn::security::DummyTpm::setTpmPassword ( const uint8_t *  password,
size_t  passwordLength 
)
virtual

set password of TPM

Password is used to unlock TPM when it is locked. You should be cautious when using this method, because remembering password is kind of dangerous.

Parameters
passwordThe password
passwordLengthThe length of password

Implements ndn::security::SecTpm.

Definition at line 270 of file dummy-keychain.cpp.

◆ resetTpmPassword()

void ndn::security::DummyTpm::resetTpmPassword ( )

◆ setInTerminal()

void ndn::security::DummyTpm::setInTerminal ( bool  inTerminal)
virtual

Set inTerminal flag to inTerminal.

If the inTerminal flag is set, and password is not set, TPM may ask for password via terminal. inTerminal flag is set by default.

virtual

Unlock the TPM.

Parameters
passwordThe password.
