Variables ¶

var NoSignParameters = []string{SIGN_STRING, KEYTYPE_STRING, SALT_STRING}

These params do not participate in url signing, sign, keytype, salt.

Functions ¶

func FetchUrl ¶

func FetchUrl(urlObj *url.URL, srcReq *http.Request, queryParams url.Values, prefix, signkey string, keytypeBlacklist,
	openScopes []string, openNormal bool, rcloneBinary, rcloneConfig, encryltedUrlPath string, authenticator *auth.Auth,
	doLog bool) (*http.Response, error)

func Generate ¶

func Generate(targetUrl, eid, key, publicurl, prefix string,
	cipher cipher.AEAD) (canonicalurl string, sign, encryptedurl, entryurl, encryptedEntryurl string)

func NewReadCloserReplacer ¶ added in v0.12.0

func NewReadCloserReplacer(src io.Reader, subs [][2]string, subrs [][2]string,
	subbs [][2][]byte) (io.ReadCloser, error)

Return a ReadCloser stream that do find-and-replacements to src on the fly. The Close func of returned value is no-op if src ifself is not a Closer.

func Parse ¶ added in v0.12.0

func Parse(prefix, fromurl, publicurl string) (plainurl, encryptedEntryurl, entryurl, eid string, err error)

func ProxyFunc ¶

func ProxyFunc(w http.ResponseWriter, r *http.Request, prefix, key string, keytypeBlacklist, openScopes []string,
	openNormal, supressError, doLog bool, enableUnix, enableFile, enableRclone, enableCurl, enableExec bool,
	rcloneBinary, rcloneConfig, curlBinary string, cipher cipher.AEAD, authenticator *auth.Auth)

func Realkey ¶

func Realkey(key, keytype string) string

key and keytype are guaranteed to do not contain \n. Put keytype (plaintext) first, to increase security against length extension attack. See https://en.wikipedia.org/wiki/Length_extension_attack . We use HMAC to derive signing key from Realkey() output, so it's only a double security.

Types ¶

type ReadCloserReplacer ¶ added in v0.12.0

type ReadCloserReplacer struct {
	io.Reader
	// contains filtered or unexported fields
}

func (*ReadCloserReplacer) Close ¶ added in v0.12.0

func (r *ReadCloserReplacer) Close() error

type Response ¶ added in v0.12.0

type Response struct {
	Err     error
	Status  int
	Header  http.Header
	Body    string
	Data    any
	RawBody io.ReadCloser
}

type Template ¶ added in v0.11.0

type Template interface {
	Execute(wr io.Writer, data any) error
}
