After that, we will introduce the new module cryptographer in the Enterprise Library. This module plays an important role in most daily projects, for example: the website member password, ID card number, and website configuration can be encrypted to ensure the security of project data. We will introduce the following points today: 1. Simple Analysis of the enterprise database cryptographer (encryption module. 2. Implement a custom

All we need to do is to declare a column to be encrypted and the rest to be done by Oracle. When the user inserts or updates data, the column values are intercepted, encrypted, and then saved in the encrypted format. Then, when the column is queried, the value of the column is automatically decrypted, and the decrypted text (plaintext) is returned to the user. Users do not even need to know that there has been encryption and decryption--the so-called

Like Windows BitLocker, the Encrypting File System (EFS, Encrypting File System) is a set of public key-based encryption mechanisms built into windows that can encrypt files and folders on NTFS partitions, enabling real-time, Transparently encrypts the data on the disk.Cryptographic operationsEncryption method The user is transparent, after the file encryption, d

Summary of Cocos2d-x resource encryption and decryption practices, cocos2d-x encryption and decryption This article is Siliphen original, reproduced please indicate the source: http://blog.csdn.net/stevenkylelee This article is aimed at the cocos2d-x 3.4 version of research. How to implement encryption and decryption Brief Introduction to

1. Concept: Springcloudconfig Advanced Configuration2. Specific contentIn Springcloudconfig, considering the security issues that all profiles are exposed to in the remote repository, there is a handling mechanism for secure access that encrypts some data and enables decryption control when read.2.1, key encryption processingThe so-called key processing refers to setting a public operation access password, and then through the Curl command to access t

Most of the time to the secret to be persistent encryption, at this time the encryption using MD5. When symmetric encryption is used, the Des method is used.1 Importjava.io.IOException;2 Importjava.security.MessageDigest;3 ImportJava.security.SecureRandom;4 5 ImportJavax.crypto.Cipher;6 ImportJavax.crypto.SecretKey;7 Importjavax.crypto.SecretKeyFactory;8 ImportJa

There are two articles worth looking at:https://blog.csdn.net/wgw335363240/article/details/8878584 Conclusion: 1 AES encryption time and the size of the encrypted file is growing linearly, encrypting 1G of the file will take about 4 minutes, encryption speed is still very fast 2 The encrypted file size is twice times the size of the original file 3 The time required to decrypt the file is twice times the

It is estimated that there will be more updates in cryptography over time. Asymmetric Encryption:Asymmetric encryption is the opposite of symmetric encryption concept, symmetric encryption refers to the encryption and decryption using the same key keys, such as Stream encryption
