func BreakRepeatingXOR ¶

func BreakRepeatingXOR(input []byte) ([][]byte, error)

BreakRepeatingXOR returns the top keys for the given input. The input is expected to be encrypted using the 'repeating-key XOR'

func DecryptAES128ECB ¶

func DecryptAES128ECB(data, key []byte) ([]byte, error)

DecryptAES128ECB decrypts the data encoded with AES128 in ECB.

func DecryptXOR ¶

func DecryptXOR(cipher []byte) [][]byte

func DetectAES128ECB ¶

func DetectAES128ECB(ciphers [][]byte) int

DetectAES128ECB detects if some cipher was encoded using aes 128 ecb. If found returns the index of the ciper, -1 otherwise.

func DetectXORCipher ¶

func DetectXORCipher(ciphers [][]byte) [][]byte

func EncryptRXOR ¶

func EncryptRXOR(msg, key []byte) error

func FindKeySizes ¶

func FindKeySizes(from, to int, input []byte) ([]int, error)

FindKeySize tries keysizes from the given range. Returns all keysizes sorted from the best score to the lowest score.

func FixedXor ¶

func FixedXor(upper []byte, lower []byte) ([]byte, error)

func HammingDistance ¶

func HammingDistance(first, second []byte) (uint64, error)

HammingDistance returns the number of different bits of the two byte slices. Returns an error if their lengths don't match.

func HexToBase64 ¶

func HexToBase64(b []byte) []byte

HexToBase64 converts the bytes b in hex to base64.
