Article Introduction：Folder encryption is a common way to protect personal and confidential files. When we need to protect certain files or folders from being accessed or viewed by others, we can choose to encrypt the folder. However, sometimes when we no longer need to encrypt a certain folder, we need to know how to unencrypt the folder. The method of decrypting a folder varies slightly depending on the operating system. In this article, I will introduce the steps to decrypt folders under Windows and Mac systems. For Windows systems: Open encrypted files

Article Introduction：OpenSSL uses cryptographic methods to encrypt or decrypt files 1. Use openssl to encrypt a file (data.zip is the original file, back.zip is the encrypted file) #opensslenc-e-aes256-indata.zip-outback.zip explanation: enc means Symmetrically encrypt or decrypt the file, -e means to encrypt a file, -aes256 means to use the aes256 algorithm for encryption, -in means the file that needs to be encrypted, -out means a new file generated after encryption. During the encryption process, you will be asked to enter an encryption password. Enter it twice to complete the encryption of the file. 2. Use openssl to decrypt.

Article Introduction：Deeply understand the file encryption and decryption technology in Java development. With the advent of the Internet and the digital age, the security requirements for files and data are getting higher and higher. In Java development, file encryption and decryption technology has become a key technology, which can protect sensitive data, prevent data leakage and illegal access. This article will delve into file encryption and decryption technology in Java development, including symmetric encryption algorithms and asymmetric encryption algorithms. 1. Symmetric encryption algorithm Symmetric encryption algorithm refers to an algorithm that uses the same key for encryption and decryption operations. Commonly used

Article Introduction：In Linux systems, you can use GPG (GNUPrvacyGuard) to encrypt and decrypt files. GPG is an open source encryption software used to ensure the confidentiality of files and communications. Here are the basic steps to encrypt and decrypt files using GPG: Encrypt files: Open a terminal and be logged in as the user logged into your Linux system. Generate a GPG key pair: Run the following command to generate a GPG key pair: gpg --gen-key Follow the prompts and provide the necessary information such as name, email address, and password. This information will be used to generate a key pair. Encrypt files: Run the following command to encrypt files: gpg -e -r substitution

Article Introduction：Sharing of PHP encryption and decryption functions, one is Discuz!'s authcode encryption function (with detailed breakdown), and the other is the encrypt() function. PHP needs to be used to encrypt specific information, that is, an encrypted string is generated through the encryption algorithm. This encrypted string can be decrypted through the decryption algorithm to facilitate the program to process the decrypted information.

Article Introduction：As the PHP version is upgraded, some functions have been abandoned, such as encryption and decryption functions. Before PHP7.1, decryption and encryption were implemented through mcrypt_decrypt() and mcrypt_encrypt(), and after PHP7.1 through openssl_decrypt() and openssl_encrypt(). Decryption and encryption. Here, through the encapsulation class, two implementation methods are used to implement two methods of encryption and decryption steps: the original data is returned during decryption (array-->encryption-->encrypted string--&g...
