func Xor ¶

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

Xor encodes an amd64 payload using the Metasploit x64/xor scheme.

func XorDynamic ¶

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

XorDynamic encodes an amd64 payload using the Metasploit x64/xor_dynamic scheme. If key includes a trailing key terminator + payload terminator (3 bytes) that satisfy the encoder constraints, those are used verbatim.

Note: For large/high-entropy payloads, a 2-byte payload terminator may not exist. In that case, this implementation falls back to a 4-byte payload terminator.

func XorDynamicKeyGen ¶

func XorDynamicKeyGen() ([]byte, error)

XorDynamicKeyGen returns a random key suitable for the XOR dynamic encoder.

func XorDynamicKeyGenForPayload ¶ added in v1.7.6

func XorDynamicKeyGenForPayload(data []byte, badChars []byte) ([]byte, error)

XorDynamicKeyGenForPayload returns a payload-aware key whose encoded bytes avoid badChars. Empty badChars use the xor_dynamic defaults.

func XorDynamicWithBadChars ¶ added in v1.7.6

func XorDynamicWithBadChars(data []byte, key []byte, badChars []byte) ([]byte, error)

XorDynamicWithBadChars encodes an amd64 payload while excluding badChars from the complete output. Empty badChars use the xor_dynamic defaults.

func XorKeyGen ¶

func XorKeyGen() ([]byte, error)

XorKeyGen returns a random key suitable for the XOR encoder.
