applet jar自签名的-tsa或-tsacert时间戳（i20签名日期）

当我尝试自签名时，如下所示。

jarsigner -keystore my keystore myjar.jar myalias

它给出如下警告：

没有提供-tsa或-
tsacert，并且这个jar没有时间戳记。如果没有时间戳，则用户可能无法在签署者证书的到期日期（2014-05-08）或以后的任何吊销日期之后验证此jar。

请帮助解决问题。

小编典典

最近的Java 7提供了（礼貌吗？）关于已经存在十年的警告。

Trusted Timestamping在Java 5（2004）中引入。这样做的动机是当证书过期时，不会强迫开发人员“每年重新签名已部署的JAR文件”。

→ http://docs.oracle.com/javase/1.5.0/docs/guide/security/time-of-
signing.html

通常，颁发证书的证书颁发机构（CA）提供基于URL的时间戳颁发机构（TSA） ，以与 CA颁发的 证书相同 。例如，digicert tsa
url可以按以下方式访问：

jarsigner -tsa http://timestamp.digicert.com [.. other options]

→ http://www.digicert.com/code-signing/java-code-signing-
guide.htm

具有自签名证书的时间戳 可能是 一个难以实现的目标，因为（1）TSA时间戳需要是一个受信任的独立交易（排除“自我时间戳”），并且（2）设置了典型的TSA
URL以与之配合使用由同一CA组织提供的证书（即TSA URL不处理自签名证书）

更新：

尝试给带有自签名证书的时间戳记的URL：

赛门铁克：（-tsa http://sha256timestamp.ws.symantec.com/sha256/timestamp根据brad-turek的评论）

对于专用网络，可以考虑使用内部时间戳记授权机构，例如Thales（nCipher）时间戳服务器（或以前称为OpenTSA）

android – 当WhatsApp的源代码不可用时,人们如何开发像GBWhatsapp等WhatsApp mod(具有额外功能)？

许多第三方whatsapp mods开发了很多很酷的功能,如自动回复,感兴趣的人上线时的通知,消息计时器等.
当whatsapp没有发布任何源代码并且逆向工程变得过于强硬时,这些人能够构建这样的功能吗？

解决方法:

他们使用逆向工程,逆向工程工具,第三方,封闭,二进制Android应用程序.这些工具可以将资源解码为接近原始形式,并在进行一些修改后重建它们.它还使得使用应用程序更容易,因为项目如文件结构和一些重复性任务的自动化,如构建apk等.

>将资源分解为近乎原始的形式(包括resources.arsc,classes.dex,9.png.和XML)
>将解码后的资源重建为二进制APK / JAR

Applied Arts and Fine Arts

Although we now tend to refer to the various crafts according to the materials used to construct them—clay, glass, wood, fiber, and metal—it was once common to think of crafts in terms of function, which led to their being known as the "applied arts." Approaching crafts from the point of view of function, we can divide them into simple categories: containers, shelters and supports. There is no way around the fact that containers, shelters, and supports must be functional. The applied arts are thus bound by the laws of physics, which pertain to both the materials used in their making and the substances and things to be contained, supported, and sheltered. These laws are universal in their application, regardless of cultural beliefs, geography, or climate. If a pot has no bottom or has large openings in its sides, it could hardly be considered a container in any traditional sense. Since the laws of physics, not some arbitrary decision, have determined the general form of applied-art objects, they follow basic patterns, so much so that functional forms can vary only within certain limits. Buildings without roofs, for example, are unusual because they depart from the norm. However, not all functional objects are exactly alike; that is why we recognize a Shang Dynasty vase as being different from an Inca vase. What varies is not the basic form but the incidental details that do not obstruct the object''s primary function.

Sensitivity to physical laws is thus an important consideration for the maker of applied-art objects. It is often taken for granted that this is also true for the maker of fine-art objects. This assumption misses a significant difference between the two disciplines. Fine-art objects are not constrained by the laws of physics in the same way that applied-art objects are. Because their primary purpose is not functional, they are only limited in terms of the materials used to make them. Sculptures must, for example, be stable, which requires an understanding of the properties of mass, weight distribution, and stress. Paintings must have rigid stretchers so that the canvas will be taut, and the paint must not deteriorate, crack, or discolor. These are problems that must be overcome by the artist because they tend to intrude upon his or her conception of the work. For example, in the early Italian Renaissance, bronze statues of horses with a raised foreleg usually had a cannonball under that hoof. This was done because the cannonball was needed to support the weight of the leg. In other words, the demands of the laws of physics, not the sculptor''s aesthetic intentions, placed the ball there. That this device was a necessary structural compromise is clear from the fact that the cannonball quickly disappeared when sculptors learned how to strengthen the internal structure of a statue with iron braces (iron being much stronger than bronze).

Even though the fine arts in the twentieth century often treat materials in new ways, the basic difference in attitude of artists in relation to their materials in the fine arts and the applied arts remains relatively constant. It would therefore not be too great an exaggeration to say that practitioners of the fine arts work to overcome the limitations of their materials, whereas those engaged in the applied arts work in concert with their materials.
