This article all source code download:/files/chnking/encryptlongdata.rarI. Use of certificates combined with symmetric encryption algorithm to add and decrypt Long dataThe previous section discussed how to encrypt data using RSA certificates, which mentions: "The RSA implementation of dotnet has a characteristic that it must add some random numbers in the clear text, so the plaintext cannot fill 128 bytes,
Objective:
Recently accidentally and colleagues to exchange data security transmission problems, think of their own used RSA asymmetric encryption algorithm, idle down to sum up.

Preface
I have written many articles about data migration and introduced many tools and features related to HDFS, suchDistcp, viewfilesystemAnd so on. But the theme I want to talk about today has moved to another field.Data securityData security has always been a key concern for users. Therefore, data managers must follow the following principles:
The data is not

Preface
For encrypted data transmission, there are several methods that people often use. One is ciphertext transmission, and the other is ciphertext transmission. The other is to encrypt
Recently accidentally and colleagues to exchange data security transmission problems, think of their own used RSA asymmetric encryption algorithm, idle down to sum up.
What is RSA encryption?
RSA algorithm is the most popular public key cryptography algorithm, using the length can change the key. RSA is the first algorithm that can be used both for
This article will introduce some programming skills of Software Encryption locks, as well as how software developers can write secure and reliable code, and how to deal with various dongle attacks, some issues that should be avoided when writing encryption programs. The following is the full text.

Generally, the "^" exclusive or operation is used to encrypt strings.

One, professional high strength encryption
The following several encryption software are professional high-strength encryption, suitable for high confidentiality of the file, once the password lost 99% can not be recovered.
1.BitLocker (recommended)
Windows 7/WINDOWS8/WINDOWS10 systems are equipped with Windows Bi
two-factor identity authentication technology, can effectively protect user privacy and confidential information, to prevent the leakage of these sensitive information caused by loss and inconvenience.Key benefits of Secure folder encryption software:1, the new encryption kernel, professional encryption algorithm, to
Come straight to the point, I am not a VIP, I need encryption software?
A: In this information age, I think it is necessary. For example, some of the bank's password information, some files, perhaps action movies, or some of the predecessor's things. Everyone should have a place that they think is safe.
There are so many encryption
Preface:
A colleague consulted me about the implementation of Android DES Encryption, a simple implementation, today to sum up.

Objective:
These days the company temporarily pulled to do Android IM instant Messaging protocol implementation, the general view of their agreement, because the previous did not participate, is said to be due to server performance restrictions, only to achieve a non-clear delivery, specific reasons I am not clear, but the encryption used here is the use of XOR or encryption. This
Mobile file encryption softwareEncrypt your phone files what would you do? Some people will say this is very simple, directly to the phone screen lock screen can be, this is really too low, a little closer to a person or a people who have looked at once will know your boot password. So be sure to find a professional file encryption software, so as to be able to p
Objective:
In addition to landing in the project, payment and other interfaces using RSA asymmetric encryption, outside the use of AES symmetric encryption, today we come to understand the AES encryption.

Many software developers think that software encryption is to protect the software from being copied. During encryption, after all, encryption developers seldom or never plan on how to encrypt the
Tell everyone the simplest way to distinguish: Any software that claims to have "lightning encryption", "instant encryption", and "one-second encryption" functions must be pseudo encryption software! What is typical is the high-in
