Functions ¶

func ASCIIBytesToPrintString ¶

func ASCIIBytesToPrintString(b []byte) string

ASCIIBytesToPrintString converts the buffer b to the closest ASCII string equivalent, substituting '*' for unprintable characters.

func CtIsZero ¶

func CtIsZero(b []byte) bool

CtIsZero returns true iff the buffer b is all 0x00, doing the check in constant time.

func EnsureAddrIPPort ¶

func EnsureAddrIPPort(a string) error

EnsureAddrIPPort returns nil iff the address is a raw IP + Port combination.

func ExplicitBzero ¶

func ExplicitBzero(b []byte)

ExplicitBzero explicitly clears out the buffer b, by filling it with 0x00 bytes.

func GetExternalIPv4Address ¶

func GetExternalIPv4Address() (net.IP, error)

GetExternalIPv4Address attempts to guess an external IPv4 address by interface enumeration.

func MkDataDir ¶

func MkDataDir(f string) error

MkDataDir creates a data directory of appropriate (paranoid) permissions if it does not exist, and validates that existing directories have the intended permissions if it does exist.
