PHP combined with MD5 implementation of encryption and decryption method, PHP combined with MD5 encryption decryption This paper describes the encryption and decryption method implemented by PHP combined with MD5. Share to everyone for your reference, as follows: Recently in the collation of the code found a good thing, combined with MD5

Definition of hardware encryption and Software Encryption 1. hardware encryption is implemented through a dedicated encryption chip or an independent processing chip. When the encryption chip, private electronic key, and hard disk are matched one by one, the

Asymmetric Cryptography Concepts 1, the main difference with the symmetric encryption algorithm is that encryption and decryption of the key is not the same, a public (public key), a secret (private key). This paper mainly solves the problem of key distribution management of symmetric encryption algorithm, and improves the security of the algorithm. 2, the asym

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

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

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
