Binary plaintext string encryption: reduction and anti-reduction
Background The previous article introduced the principle of xorstr and the code of the minimal verification concept. This article looks at how to restore this technology that has been widely used in various malicious samples and security components. If you haven’t read the previous suggestion, Read it first to understand its implementation before reading this […]

[Qt controls QLineEdit, QPlainTextEdit, QTextEdit, QTextBrowser] usage and differences
Introduction QLineEdit, QPlainTextEdit, QTextEdit and QTextBrowser are all controls used for text input and display in Qt. There are some differences between them and they are suitable for different scenarios. The following is a brief introduction, differences and usage tips for these four categories: Function Name Function QLineEdit QLineEdit is a simple single-line text input […]

Suppose the ciphertext obtained by encrypting a plaintext by affine transformation is: `edsgi ckxhu klzve qzvkx wkzuk vcuh` and it is known that the first two characters of the plaintext are `if`, decrypt the ciphertext (known plaintext attack)
Suppose the ciphertext obtained by encrypting a plaintext by affine transformation is: edsgi ckxhu klzve qzvkx wkzuk vcuh It is also known that the first two characters of the plaintext are if, Decrypt the ciphertext (known plaintext attack) Suppose we are studying a known-plaintext attack on an affine cipher. Affine ciphers are simple substitution ciphers […]
Connect to TiDB with a non-plaintext password on the command line
Author: GangShen Original source: https://tidb.net/blog/6794a34b During the process of connecting to TiDB on the command line, in order to protect the password from being obtained in plain text, you can use a non-plain text password to connect. This article records several ways to connect to TiDB in non-plaintext. Method 1: Command line input method [root@iZuf6d7xln13sovvijl68rZ […]
C#: AES encryption and decryption for plaintext encryption
Vernacular comprehension: Translate the characters that can be seen with a clear eye into another language that cannot be read, just like Morse code…just like base64 encryption, both have the same effect. Create a new class (the method of aes encryption and decryption is placed here) public static class AesPassword {<!– –> /// <summary> /// […]

Securely access keys on the command line, avoiding plaintext keys in the CLI
Use pass to securely use and save keys in the Linux CLI, avoiding including plaintext keys on the command line or configuration files pass (short for password-store) is a simple command-line password manager for Linux. It stores passwords in a GPG-encrypted file. These encrypted files are well organized and stored in a directory structure. Because […]
