func NewXZReader(r io.Reader) (io.ReadCloser, error)

NewXZReader uses the xz command to extract the Apple Archives (xz streams) or falls back to the pure Golang xz decompression lib

func Parse ¶

func Parse(payload *zip.File, folder, extractPattern string) (bool, string, error)

Parse parses a ota payload file inside the zip

func RemoteExtract ¶

func RemoteExtract(zr *zip.Reader, extractPattern, destPath string, shouldStop func(string) bool) ([]string, error)

RemoteExtract extracts and decompresses remote OTA payload files

func RemoteList ¶

func RemoteList(zr *zip.Reader) ([]os.FileInfo, error)

RemoteList lists the files in a remote ota payloads

Types ¶

type AA ¶

type AA struct {
	Reader
	// contains filtered or unexported fields
}

func NewOTA ¶

func NewOTA(r io.ReaderAt, size int64) (*AA, error)

func Open ¶

func Open(name string, conf *Config) (*AA, error)

Open opens an OTA file with optional configuration If conf is nil, default configuration is used (automatic key lookup)

func (*AA) Close ¶

func (a *AA) Close() error

	Proxy string
	// Insecure allows insecure connections when fetching AEA keys
	Insecure bool
}

Config holds optional configuration for opening OTA files
