Functions

func Argon2IDPasswordHash

func Argon2IDPasswordHash(plain string, conf Argon2idConfig) (string, error)

func Argon2IDPasswordVerify

func Argon2IDPasswordVerify(hash, plain string) error

func BytesToString

func BytesToString(in []byte) string

func MarshalED25519PrivateKey

func MarshalED25519PrivateKey(key ed25519.PrivateKey) []byte

MarshalED25519PrivateKey writes ed25519 private keys into the new OpenSSH private key format. I have no idea why this isn't implemented anywhere yet, you can do seemingly everything except write it to disk in the OpenSSH private key format. taken from https://github.com/mikesmitty/edkey/blob/master/edkey.go

func MercuryInRetrograde

func MercuryInRetrograde() (bool, error)

Types

type Argon2idConfig

type Argon2idConfig struct {
	Memory      uint32 // KiB - main "knob" to turn for more expensive hashes
	Iterations  uint32 // if memory cant go higher, iterations should, to compensate
	Parallelism uint8  // used to spread the load across multiple CPU threads (if used, iterations should be increased)

	SaltLen uint32 // bytes
	KeyLen  uint32 // bytes
}

Argon2idConfig provides an easier structure for Argon2id password hashing.

The main gist (not 100% accurate, but close enough) is: complexity = memory * iterations / parallelism.

func DefaultArgon2idConf

func DefaultArgon2idConf() Argon2idConfig

DefaultArgon2idConf provides standard sane parameters chosen to not overload the parser service.
