How to use zip-stream - 7 common examples

ZipAesStream.prototype._writeLocalFileHeader = function (ae) {
    let gpb = ae.getGeneralPurposeBit();

    // set AES-specific fields
    gpb.useEncryption(true);
    ae.setExtra(_buildAesExtraField(ae));
    ae.setMethod(ZIP_AES_METHOD);
    ae.setVersionNeededToExtract(51);

    ZipStream.prototype._writeLocalFileHeader.call(this, ae);
};

ZipCryptoStream.prototype._writeLocalFileHeader = function (ae) {
    // set encryption
    ae.getGeneralPurposeBit().useEncryption(true);
    ZipStream.prototype._writeLocalFileHeader.call(this, ae);
};

ZipCryptoStream.prototype.entry = function(source, data, callback) {
  return ZipStream.prototype.entry.call(this, source, data, callback);
};

ZipCryptoStream.prototype._appendStream = function(ae, source, callback) {
  ae.gpb.useEncryption(true);
  ZipStream.prototype._appendStream.call(this, ae, source, callback);
};

ZipCryptoStream.prototype._normalizeFileData = function(data) {
  return ZipStream.prototype._normalizeFileData.call(this, data);
};
