Types

type Config 

type Config struct {
	RuleList    []Rule
	Whitelist   []FileType
	Blacklist   []FileType // most common
	SkipFolder  []FileType //
	MaxFileSize int        // default: 0 as 4kb, -1 as any size
	MiniWeight  float64    // minimum portion of a secret file, excluding x.509, <= 0.0: no minimum
	TimeoutSec  uint       // in seconds
}

Config is a configuration is a composite struct of RuleList and file lists

type Entropy 

type Entropy struct {
	Group int // index of capturing groups, 0: all
	Min   float64
	Max   float64 // 5.95 for key[56]1..0A..Z..az
}

Entropy represents an entropy range

type FileType 

type FileType struct {
	Description string
	Expression  string
	Regex       *regexp.Regexp
	MinEntropy  float64
}

FileType is a file spefification

type Rule 

type Rule struct {
	Description string
	Expression  string
	ExprFName   string
	ExprFPath   string
	Regex       *regexp.Regexp
	FNameRegex  *regexp.Regexp
	FPathRegex  *regexp.Regexp
	Tags        []string
	Entropies   []Entropy
	Suggestion  string
}

Rule is used in the Config struct as an array of Rules and is iterated over during an audit. Each rule will be checked.
