analyze

type Analyzer ¶

type Analyzer[T []CaesarResult | []VigenereResult] interface {
	/*
		AnalyzeBuffer analyzes the given byte buffer and returns a slice of results
		containing the detected key(s) and their corresponding chi-squared scores.
	*/
	AnalyzeBuffer(buffer []byte) (T, error)
}

Analyzer defines the interface for cipher analysis implementations.

type CaesarAnalyzer ¶

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

CaesarAnalyzer performs statistical analysis to crack Caesar cipher encrypted text.

It uses chi-squared frequency analysis to determine the most likely key.

func NewCaesarAnalyzer() *CaesarAnalyzer

func (analyzer *CaesarAnalyzer) AnalyzeBuffer(buffer []byte) ([]CaesarResult, error)

type CaesarResult ¶

type CaesarResult struct {
	Key      byte
	ChiScore float64
}

CaesarResult holds the analysis result for Caesar cipher, containing the detected key and its chi-squared score.

type VigenereAnalyzer ¶

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

VigenereAnalyzer performs statistical analysis to crack Vigenère cipher encrypted text.

It uses n-gram frequency analysis and Kasiski examination to determine the key length, then applies Caesar cipher analysis to each character position to recover the key.

func NewVigenereAnalyzer(maxNgramLength int) (*VigenereAnalyzer, error)

func (analyzer *VigenereAnalyzer) AnalyzeBuffer(buffer []byte) ([]VigenereResult, error)

type VigenereResult ¶

type VigenereResult struct {
	Key      []byte
	ChiScore float64
}

VigenereResult holds the analysis result for Vigenère cipher, containing the detected key and its chi-squared score.
