Want to reinstall the system, but there is no CD-ROM and u disk, how to do? Don't worry, here's to tell you how to install a system without a disc without a U disk! Download the ISO image first, and then install the virtual CD drive on your computer, because the virtual CD drive can also read the mirrored file, so you can install the system.

a virtual disk, the virtual disk is writable! Although the original compressed package is in read-only state, the files inside will not be changed, but you can completely as a local disk, in which the new directory, modify, and so on. In this way, not only meet some special needs, but also ensure the security of the original file. Similarly, you can mount a folder as a virtual disk, and any action on it will not affect the original file content. The Mount

You can use it to visually modify the CD-ROM image file (ISO), hide the directories and files in the optical image file specifically, turn the normal files into oversized files, and make the normal directory into a file directo

DotNet encryption-symmetric encryption and dotnet encryption -- Just one day before the Chinese New Year's Eve, it's close to you to go home. Some people are excited, because they will have to go through the annual installation drama in a few days, and all the parties, including relatives, friends, and students, will show off, therefore, I have to pay a year-end

Symmetric encryption and asymmetric encryption, asymmetric encryption What is encryption? Encryption is divided into two parts: algorithm and key. The algorithm remains unchanged, and the key changes. For more information, see the following example. Key: abcedfgh-> 12345678.

When it comes to encryption, it's reminiscent of digital signatures, what are the two often confusing concepts?Encryption: Encryption is a way to send information in a password. Only the person with the correct key can unlock the password for this message. For others, the message looks like a series of random letters, numbers, and symbols.

When it comes to encryption, a digital signature is associated with two concepts that are often confused. Encryption: Encryption is a way to send information in a password way. Only the person with the correct key can unlock the password for this information. For other people, this information looks like a series of random letters, numbers, and symbols.

[Preface]This article briefly introduces the concepts related to encryption technology, and finally summarizes the existing encryption technology in java as well as its usage and examples. [Simple encryption] 1. Simple concept Plaintext: the information before encryption Ciphertext: Confidential Information Algorithm

For security reasons, we typically choose an encryption method to encrypt text that requires security, while BASE64 encryption and DES64 encryption are common cryptographic algorithms. I remember what I used in the previous project was the combination of these two cryptographic algorithms: Base64 + des encryption. Of c

Symmetric encryption and asymmetric encryption, asymmetric encryptionSafe communication methods must meet the following three conditions:1. Integrity, that is, the message has not been tampered with midway through.2. Confidentiality, which cannot be decrypted by a third party.3. verifiable. The message receiver can determine who sent the message. Symmetric encryption
