Functions ¶

func ConstantRetriever ¶

func ConstantRetriever(constantPassphrase string) notary.PassRetriever

ConstantRetriever returns a new Retriever which will return a constant string as a passphrase.

func GetPassphrase ¶

func GetPassphrase(in *bufio.Reader) ([]byte, error)

GetPassphrase get the passphrase from bufio.Reader or from terminal. If typing on the terminal, we disable terminal to echo the passphrase.

func PromptRetriever ¶

func PromptRetriever() notary.PassRetriever

PromptRetriever returns a new Retriever which will provide a prompt on stdin and stdout to retrieve a passphrase. stdin will be checked if it is a terminal, else the PromptRetriever will error when attempting to retrieve a passphrase. Upon successful passphrase retrievals, the passphrase will be cached such that subsequent prompts will produce the same passphrase.

func PromptRetrieverWithInOut ¶

func PromptRetrieverWithInOut(in io.Reader, out io.Writer, aliasMap map[string]string) notary.PassRetriever

PromptRetrieverWithInOut returns a new Retriever which will provide a prompt using the given in and out readers. The passphrase will be cached such that subsequent prompts will produce the same passphrase. aliasMap can be used to specify display names for TUF key aliases. If aliasMap is nil, a sensible default will be used.
