Functions

func SHA1Hash

func SHA1Hash(inp []byte) []byte

SHA1Hash returns the SHA1 of the input

func SHA256Hash

func SHA256Hash(inp []byte) []byte

SHA256Hash returns teh SHA256 of the input

func SaltID

func SaltID(salt, id string, hash HashFunc) string

SaltID is used to apply a salt and hash functio to an ID to make sure it is not reversable

Types

type Config

type Config struct {
	// Location is the path in the storage backend for the
	// salt. Uses DefaultLocation if not specified.
	Location string

	// HashFunc is the hashing function to use for salting.
	// Defaults to SHA1 if not provided.
	HashFunc HashFunc
}

Config is used to parameterize the Salt

type HashFunc

type HashFunc func([]byte) []byte

type Salt

type Salt struct {
	// contains filtered or unexported fields
}

Salt is used to manage a persistent salt key which is used to hash values. This allows keys to be generated and recovered using the global salt. Primarily, this allows paths in the storage backend to be obfuscated if they may contain sensitive information.

func NewSalt

func NewSalt(view logical.Storage, config *Config) (*Salt, error)

NewSalt creates a new salt based on the configuration

func (*Salt) DidGenerate

func (s *Salt) DidGenerate() bool

DidGenerate returns if the underlying salt value was generated on initialization or if an existing salt value was loaded

func (*Salt) SaltID

func (s *Salt) SaltID(id string) string

SaltID is used to apply a salt and hash functio to an ID to make sure it is not reversable
