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, the actual test, the plaintext is up to 117 b

SQL Server encryption and SQL Server encryption Encryption in SQL Server is hierarchical, and each upper layer provides lower protection. Instance:/**SMK (Service Master Key) is generated when SQL Server is installed. It is protected by Windows DPAPI (Data Protection API ).**/ /** Create a Database-level DMK (Database Master Key), protected by SMK **/Create mast

doesn't matter if they can use software to crack it. Finally, many people think that using such pseudo-software is not dangerous. In fact, there may not be many people who crack it, but the key is that they use some windows skills to achieve "encryption, in your daily use, what other operations have you done? As a result, your "encrypted" file disappears. Isn't it enough to regret it? If you find that your friends use the software you just mentioned,

We have introduced the core implementation principles of mainstream double-layer encryption shells,And compatibility, while simplifying the encryption Shell Core with security considerations.The compatibility and security of the encryption Shell Core are discussed, and the Implementation Mode of the encryption Shell Co

Digital signatures are common: Before learning about digital signatures, you must first understand the SHA-1 digest and RSA encryption algorithm. Then, learn more about digital signatures.SHA-1 SHA-1 (secure hash algorithm) is Data encryption algorithm.The idea of this algorithm is to receive a piece of plain text, and then convert it into a section (usually smaller) ciphertext in an irreversible way, it ca

standard| Encryption | Decrypting this class is my online reference to a few documents summed up, test can be used directly, behind a section of MD5, should be independent into a class, I am lazy, so the test is written to a file, feeling is still full of practical, if there are any confidential documents, Use this thing to deal with, in the future to see when the reverse processing, but you do not forget the password on the right, if you are as lazy

Oracle's transparent data encryption is part of Oracle's Advanced Security Options and requires additional software fees. This option can be encrypted in combination with multiple means, including using Wallet (PKCS #12 standard) and supporting PKCS #11 RAS hardware devices. In 10 Gb, transparent encryption supports column-level encryption, while in Oracle 11gR2,

What is distorted encryption transformation? This is a software I developed. The official term may be "mixed encryption". I name my software "distorted encryption transformation technology. I spent more than a year developing this software on and off, but I didn't do any promotion. This software has not been made public until now.

In the real environment, we will encounter the loss or theft of database backup disks. At this time, malicious destructive parties only need to restore or attach the database to view data. Next, I will introduce the Transparent Data Encryption method to protect your database. If data A is encrypted using TDE, the database uses A certificate-protected encrypted data key because it cannot be restored or attached to A backup disk. 1. What is TDE? Transpa

Symmetric encryption has many a

In the previous article, I introduced some important classes of the enterprise database cryptographer module, and introduced the extended interfaces provided by the enterprise database cryptographer module. Today I will perform extended development based on these interfaces, implements two encryption and decryption methods (discrete encryption and symmetric encryption
