virtual void ndn::SecTpmFile::setTpmPassword ( const uint8_t *  password,
size_t  passwordLength 
)
inlinevirtual

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::SecTpm.

Definition at line 55 of file sec-tpm-file.hpp.

virtual void ndn::SecTpmFile::resetTpmPassword ( )

reset password of TPM

Implements ndn::SecTpm.

Definition at line 60 of file sec-tpm-file.hpp.

virtual void ndn::SecTpmFile::setInTerminal ( bool  inTerminal)
inlinevirtual

Set inTerminal flag to.

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

Implements ndn::SecTpm.

Definition at line 65 of file sec-tpm-file.hpp.

virtual bool ndn::SecTpmFile::getInTerminal ( ) const
inlinevirtual

Get value of inTerminal flag.

Implements ndn::SecTpm.

Definition at line 71 of file sec-tpm-file.hpp.

virtual bool ndn::SecTpmFile::isLocked ( )
inlinevirtual

Check if TPM is locked.

virtual bool ndn::SecTpmFile::unlockTpm ( const char *  password,
size_t  passwordLength,
bool  usePassword 
)
inlinevirtual

Unlock the TPM.

Parameters
passwordThe password.
passwordLengthThe password size. 0 indicates no password.
usePasswordTrue if we want to use the supplied password to unlock the TPM.
Returns
true if TPM is unlocked, otherwise false.
