As more and more people send confidential information through e-mail, it becomes increasingly important to ensure that documents sent in e-mail are not forged. It is also important to ensure that the messages sent are not intercepted or stolen by anyone other than the addressee. By using the digital ID of Outlook Express, you can prove your identity in an electronic transaction, as if you were to show a valid document when you pay a cheque. You can al

Digital Certificate and Its Application in Security Testing0x00 background To perform security tests on the Web layer, it is inevitable that a man-in-the-middle proxy will be used to capture packets for analysis. Common tools include BurpSuit, Fiddker, and Charles. The usage of these tools has been described on the Internet. I will not go into details here. Howev

said earlier that message digest is used to verify data integrity, and symmetric and asymmetric encryption is used to guarantee data confidentiality. Data signatures are used for the anti-repudiation of data, so the ultimate weapon that sets these security measures--digital certificates--appears. Digital certificate has the necessary information of encryption/dec

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 to the network, Sending Short Messages (SMS and MMS), or accessing mobile terminals (such
