Member Function Documentation

ClearFailureRecord()

bool cuttlefish::TpmGatekeeper::ClearFailureRecord ( uint32_t  uid, gatekeeper::secure_id_t  user_id, bool  secure  )

override

ComputePasswordSignature()

void cuttlefish::TpmGatekeeper::ComputePasswordSignature ( uint8_t *  signature, uint32_t  signature_length, const uint8_t *  key, uint32_t  key_length, const uint8_t *  password, uint32_t  password_length, gatekeeper::salt_t  salt  ) const

override

ComputeSignature()

void cuttlefish::TpmGatekeeper::ComputeSignature ( uint8_t *  signature, uint32_t  signature_length, const uint8_t *  key, uint32_t  key_length, const uint8_t *  message, uint32_t  length  ) const

override

GetAuthTokenKey()

bool cuttlefish::TpmGatekeeper::GetAuthTokenKey ( const uint8_t **  auth_token_key, uint32_t *  length  ) const

override

GetFailureRecord()

bool cuttlefish::TpmGatekeeper::GetFailureRecord ( uint32_t  uid, gatekeeper::secure_id_t  user_id, gatekeeper::failure_record_t *  record, bool  secure  )

override

Retrieves the failure record for user uid, assuming a user secret value of user_id. If the secret value user_id is incorrect, the original secret user_id value will be lost and cannot be recovered.

GetMillisecondsSinceBoot()

uint64_t cuttlefish::TpmGatekeeper::GetMillisecondsSinceBoot ( ) const

override

GetPasswordKey()

void cuttlefish::TpmGatekeeper::GetPasswordKey ( const uint8_t **  pasword_key, uint32_t *  length  )

override

GetRandom()

void cuttlefish::TpmGatekeeper::GetRandom ( void *  random, uint32_t  requested_size  ) const

override

IsHardwareBacked()

bool cuttlefish::TpmGatekeeper::IsHardwareBacked ( ) const

override

WriteFailureRecord()

bool cuttlefish::TpmGatekeeper::WriteFailureRecord ( uint32_t  uid, gatekeeper::failure_record_t *  record, bool  secure  )

override
