Http://www.cnblogs.com/feisky/archive/2010/01/17/1650076.html In Android, all applications installed on the system must have a digital certificate used to identify the author of the application and establish a trust relationship between the application, if the protectionlevel of a permission is signature, only applications with the same digital certificate as th

installed add-ins and templates check box to keep the installed macros from being disabled. Note: All templates, add-ins, and macros that follow Microsoft Office XP are digitally signed by Microsoft. Once you have added to your list of trusted sources for one of these installed files, the subsequent interaction with those files will no longer generate messages. Protection of digital certificates Many documents are from unknown sources, so security

The following is an example of digital signature using the DSA Signature Algorithm in Java. Digital signature algorithm (DSA) is a variant of Schnorr and Elgamal signature algorithms. It is used by NIST as the

Digital signatures are often used to verify software and software manufacturers to prevent software code from being corrupted in any way.---- In other words, using digital signatures ensures that the software is "clean" and "authentic ", that is, the software has not been tampered with by others during the period from its maker or publisher to the end user.---- After a brief review of the concepts of

The DSA is a variant of the Schnorr and ElGamal signature algorithm, which was used as a DSS (DigitalSignature Standard) by the United States NIST. The DSA is based on the integer finit

Four Great jQuery digital signature plug-ins and four jquery In the browser, there are many ways to plot the signature generation effect, and there are many great and intelligent jQuery plug-ins. Digital signature is the future development direction. This is the reason why

In the daily work, there are many documents need to lead the review, signature and seal, as the company's business development, Cross-border, cross-border business is increasingly common, the leadership signature seal became very troublesome, the beginning of people by mail, fax and other means to solve, but time-consuming, human and material resources. Increasingly deep in the network today, the need for l

Yesterday, in the company's code, I saw that the post build step of a VC project will use signtool to add a digital signature to the EXE generated by the project, A part of the EXE code calls the Windows API winverifytrust to verify the digital signature of the exe. Just a few days ago, I started to use

The digital signature and encryption technologies based on public key algorithms provide theoretical basis and technical feasibility for solving the above problems, the promulgation and implementation of the Electronic Signature Law of the People's Republic of China provide a legal basis for the use of digital signatur

Here first say sorry to everyone, after all, 2 years ago I wanted to write this article, but because they are too lazy has not written, but also to leave something for themselves, some days ago my boss let me do this thing found that I did not stay, and by their own impressions from the new, but found that the online writing is really some superficial, Really say just go, after all, we are the program ape, not the students, how also point more to think of something oh, so the sum of their own th

Here say sorry everybody. After all 2几 years ago, I wanted to write this article, but because he didn't bother to write. At the same time also give yourself something good. Some days ago, my boss let me do this again to find that I have not left the information, but also by their own impressions from the new. But found that the online writing is really a little superficial, really said just go. After all, we are the program ape, not the students, how to think more things oh, so the sum of their
