File encryption for enterprises is mainly used to protect information data, its working principle is actually to make the original information data to make a special algorithm change, so that the original data can not be read normally, the data read is the file encryption software changed the data, this data information is not true, so this way can be a good way to protect enterprise information.
Now there are more file encryption methods, some are using the vulnerabilities of the system to encrypt, some are through the system-driven encryption, and some use scripts for file encryption, different methods are bound to have different advantages and disadvantages, the general difference is the speed and security of encryption, under normal circumstances, the encryption speed is slower Encryption strength is higher, better security. Encryption speed is not as fast as slow encryption strength is high, but there will also be high encryption security.
Encryption is the mathematical encoding of information, which needs to be decoded if it needs to be read. The types of file encryption we use are divided into two types of keys -- one is a public key and the other is a private key. When a message is sent, the public key encrypts the message. After the encrypted information is received, the password of the information needs to be deciphered using a private key. Everyone should note that the same key cannot be both encrypted and decrypted. Therefore, information encrypted with a private key can only be decrypted using a public key, and vice versa, all to ensure that file information is secure.
File encryption software is the product of the rapid development of the information age, it belongs to one of the data management software. The main advantage of file encryption software is to protect the security of internal data data, and people inside the enterprise can only use the file and cannot be taken away. If the file is moved, the built-in application of the file encryption software will make the file unblocked, which is the benefit of enterprises using file encryption.
In fact, in addition to file encryption, there are other encryptions, in the enterprise more than one encryption is more security, as people say not afraid of ten thousand is afraid of just in case. Tianrui can provide various types of encryption software or systems, you can go to the website for more information.
File encryption can be divided into two categories according to the encryption path: one is the file encryption function that comes with the Windows system, and the other is the commercial encryption software implemented by the encryption algorithm. There are five kinds of windows system encryption methods, and commercial encryption software is divided into driver-level encryption and plug-in-level encryption; If you press the encryption algorithm, it can be divided into three categories: symmetric idea algorithm, asymmetric rsa algorithm, and irreversible aes algorithm.
