EFS encryption, our Encrypting File system, relies on our Win7 64-bit flagship download of the ISO computer's public key strategy to help users lock up files in their Win7 flagship computer, prevent files from being stolen, deleted, and read by others. But for many users, this EFS encryption is a very redundant feature. So today, we're going to explain how we can disabl
WIN8 Disabling EFS encryption is as follows:
1, right click on the desktop space, under the desktop pop-up "All applications" option, left click "All applications."
2, drag the right below the scroll bar or scroll down the mouse wheel key to find the "run" option.
3, left click "Run".

Android database encryption and android Database Encryption
1 Introduction
SQLite is a lightweight, cross-platform, open-source database engine. It has advantages in terms of read/write efficiency, total resource consumption, latency, and overall simplicity, make it the best solution for mobile platform databases (such
Preface:
A colleague consulted me about the implementation of Android DES Encryption, a simple implementation, today to sum up.

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.
Several other encryption methods:
RSA encryption of Android data encryptionAES encryption of
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
static final int default_key_size = 2048;//secret key default length public
static final byte[] Default_split =" #PART # ". GetBytes ()///when the content to be encrypted exceeds buffersize, Partsplit is used for block encryption public
static final int default_buffersize = ( DEFAULT_KEY_SIZE/8)-11;//The current secret key supports the maximum number of bytes encrypted

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.

Android DES encryption related implementation, a simple implementation of a moment, today to sum up:

file system to a real/data file system. The system must stop every process that opens files in the temporary file system, restart these processes in the real/data file system. To do this, all services must be in one of the three groups: core, main, and late_start.Core: Never disable main after startup: Shut down after the disk password is entered. Restart late_restart: Do not start before/data is decrypted and mounted.
To stimulate these behaviors, t

Add salt
The way to add salt is also varied
String+key (salt value key) and then MD5 encryption
Use string plaintext hashcode as salt, then MD5 encryption
Randomly generates a string of strings as salt and then MD5 encryption
