Best Text Editors for .NET

MangoWriter is a highly secure text editor for Windows that operates entirely offline, free from cloud services, AI integration, network connections, or telemetry, providing users with a straightforward editing environment while prioritizing content privacy. The software employs advanced AES-256-GCM encryption combined with robust key derivation techniques (Argon2id) and offers optional keyfile two-factor authentication, ensuring that no unencrypted data is ever saved to disk, effectively removing any caches or temporary files. MangoWriter enhances user security with a clipboard feature that restricts copied content to the active session, an immediate lock screen to conceal information when the user steps away, and efficient one-click redaction tools to permanently obscure selected text throughout documents. It guarantees that sensitive data buffers are cleared after use and that passwords are never stored on disk, with key information maintained solely in secure memory while a document remains open. This software is provided as clean, code-signed builds that can be installed via an MSI installer or utilized in a portable ZIP format, and it includes various secure export options for user convenience. Additionally, MangoWriter's design philosophy centers around user control, making it an ideal choice for individuals seeking a reliable and private text editing solution.
