Types

type HTTPDriver

type HTTPDriver interface {
	Do(*http.Request) (*http.Response, error)
}

HTTPDriver - The interface to send/recv HTTP data

func GetHTTPDriver

func GetHTTPDriver(origin string, secure bool, opts *HTTPOptions) (HTTPDriver, error)

GetHTTPDriver - Get an instance of the specified HTTP driver

func GoHTTPDriver

func GoHTTPDriver(origin string, secure bool, opts *HTTPOptions) (HTTPDriver, error)

GoHTTPDriver - Pure Go HTTP driver

type HTTPOptions

type HTTPOptions struct {
	Driver               string
	NetTimeout           time.Duration
	TlsTimeout           time.Duration
	PollTimeout          time.Duration
	MaxErrors            int
	ForceHTTP            bool
	DisableAcceptHeader  bool
	DisableUpgradeHeader bool
	HostHeader           string

	ProxyConfig   string
	ProxyUsername string

}

HTTPOptions - c2 specific configuration options

func ParseHTTPOptions

func ParseHTTPOptions(c2URI *url.URL) *HTTPOptions

ParseHTTPOptions - Parse c2 specific configuration options

type Jar

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

Jar - CookieJar implementation that ignores domains/origins

func NewJar

func NewJar() *Jar

NewJar - Get a new instance of a cookie jar

func (*Jar) Cookies

func (jar *Jar) Cookies(u *url.URL) []*http.Cookie

Cookies returns the cookies to send in a request for the given URL. It is up to the implementation to honor the standard cookie use restrictions such as in RFC 6265 (which we do not).

func (*Jar) SetCookies

func (jar *Jar) SetCookies(u *url.URL, cookies []*http.Cookie)

SetCookies handles the receipt of the cookies in a reply for the given URL (which is ignored).

type SliverHTTPClient

type SliverHTTPClient struct {
	Origin     string
	PathPrefix string

	ProxyURL   string
	SessionCtx *cryptography.CipherContext
	SessionID  string

	Closed bool

	Options *HTTPOptions
	// contains filtered or unexported fields
}

SliverHTTPClient - Helper struct to keep everything together
