A digital signature is a method of signing a message that is stored in electronic form. Messages that are signed by this method can be transmitted over the network. The digital signature is based on an asymmetric key encryption algorithm, such as the DSA/RSA algorithm. One of the benefits that can be achieved immediate

noun explanation Digital signature: In the ISO7498-2 standard is defined as: "Some data attached to the data unit, or the password transformation of the data unit, this data and transformation allows the receiver of the data unit to confirm the data unit source and Data unit integrity, and protect the data, to prevent the person (such as the recipient) to forge "。 Pkcs#7: Also known as the syntax standard
You can use Word macro commands to increase your productivity when you edit a document using Word. By default, the security setting for Word macros is high, and macros are automatically disabled when you run the Word Macro command. If you set the Word macro security to Medium, the Word Macro Security warning dialog box pops up every time you run the Word macro. If you set your Word macro security to low to suppress a security warning, you can increase the risk of malicious code or virus damage.
The following is an example of how to use the security hashing algorithm (HAMS) in Java to hash messages and use RSA to encrypt hash codes to implement digital signatures. If you are not familiar with digital signatures, read 《 Introduction to digital signaturesAnd java digital sig
Transferred from:Http://www.cnblogs.com/1-2-3/archive/2007/09/17/colloquialism-digital-certificate-part1.html Summary Through easy-to-understand explanations, this series allows you to easily understand the basic principles and application methods of digital signatures. (even if you are a computer-less enterprise boss, can also read this article ). Then we will gradually go deep into the technical details
Yesterday in the company's code, saw a VC project post build step will use SignTool to the project generated EXE to add a digital signature, and EXE of a block of code will call WinVerifyTrust this Windows API to verify the EXE's own digital signature. Just these days a little leisure time, under the drive of curiosity
MIDP 2.0 security mechanism and MIDlet Digital SignatureThis document is translated by wotrust according to the technical documentation MIDP 2.0: tutorial on signed midlets provided by Forum Nokia, please refer to this original English document: http://www.wotrust.com/support/resou...ts_v1_1_en.pdf at the same time. Please read this document before writing the MIDlet and signature MIDlet, so that you can ha
The digital signature is based on asymmetric encryption between the public key and the private key. The sender uses the private key to encrypt the message digest (signature). The receiver uses the public key to decrypt the message digest to verify whether the signature is owned by someone. Basic steps: Obtain the keypa
In the previous article, Autorun is very useful. The trouble is that others may use it to do bad things. Someone else may use it to run his dangerous program, steal information or even destroy the device, or even your own Autorun may be infected with viruses. One way to deal with this is to put Autorun in a directory that is not easy to guess and give it a strange name. It cannot solve the problem from the root, but it is better than no. The fundamental solution is to add a

Comments: What are the basic principles of Digital Signature and encryption? The digital signature mainly goes through the following processes: information senders use a one-way HASH function to generate information summaries; information senders use their own private key signature
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
Many online tools are available on the Internet, especially some so-called "hacker" websites that provide a large number of online cracking tools to break through Internet cafe restrictions, providing convenience for netizens while greatly increasing their access volume, I checked these online tool web pages, it is found that most of them are made using the "tegoweb" tool that allows the EXE to run on the webpage. This tool is a shared software with time restrictions, some of them are made using
Summary: This document takes the CAB file created in Microsoft. Net as an example to describe how to create a signature file so that your code can be securely published on the INTERNET. It is expected to play the role of throwing a token. I. Internet security and Digital Signature Code security is a major issue for Internet application developers and users. The
to purchase a code signature certificate, the signature of the MIDlet is not very profitable for developers, because many protected APIs require signatures to protect the interests of developers and users. Of course, some applications do not require signatures, for example, some small game software that only uses graphic APIs without internet connection. But some important applications, such as connecting
