Functions

func Concat

func Concat(b1 io.Reader, b2 io.Reader) io.Reader

Concat concatenates readers. Used for concatenating signature.tar.gz and APKINDEX.unsigned.tar.gz.

func ReadApkIndex

func ReadApkIndex(f io.Reader) (*apkutils.ApkIndex, error)

ReadApkIndex reads an APKINDEX file to a ApkIndex struct.

func SignApkIndex

func SignApkIndex(b []byte, signer Signer, pubkeyname string) (*bytes.Buffer, error)

SignApkIndex signs an APKINDEX file buffer using a sha1 digest using a prviate key file. The resulting file has the name format .SIGN.RSA.<nameof-public-key>.

Types

type Signer

type Signer interface {
	// Sign returns raw signature for the given data. This method
	// will apply the hash specified for the keytype to the data.
	Sign(data []byte) ([]byte, error)
}

A Signer is can create signatures that verify against a public key.

func LoadPrivateKey

func LoadPrivateKey(path string) (Signer, error)

LoadPrivateKey loads an parses a PEM encoded private key file and returns a Signer

func ParsePrivateKey

func ParsePrivateKey(pemBytes []byte) (Signer, error)

parsePrivateKey creates a Signer from a private key in PEM format in pemBytes.

type Writer

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

Writer provides sequential writing of APKINDEX index entries from APK files

func NewWriter

func NewWriter(w io.Writer) *Writer

NewWriter create a new writer.

func (*Writer) Close

func (w *Writer) Close()

Close closes the underlying writer, by writing a \n line.

func (*Writer) Write

func (w *Writer) Write(entry *apkutils.IndexEntry)

Write writes a APKINDEX record to the underlying writer.

func (*Writer) WriteApk

func (w *Writer) WriteApk(apk *apkutils.ApkFile)

WriteApk writes a APK file to an APKINDEX file, ie. a APKINDEX record for the APK.
