File Encryptions Tool

This file encryption tool allows you to securely encrypt and decrypt various text file formats using a customizable security key. The encrypted output is generated with strong cryptographic practices, including the Advanced Encryption Standard (AES), hash functions, and random salt, ensuring robust security. After encrypting, the output file has the same name as the original file with an ".enc" extension. For example, if you encrypt hello.txt, the resulting encrypted file will be hello.txt.enc.

How it's work

It sounds like you're describing a file encryption tool that uses the Advanced Encryption Standard (AES) algorithm with additional security features like hash functions and random salt to enhance encryption strength. This kind of encryption tool is commonly used to secure sensitive information, ensuring that only those with the correct security key can access the decrypted contents.

Key Concepts

• AES Algorithm: AES (Advanced Encryption Standard) is a symmetric encryption algorithm that is widely used for securing data. It offers strong security and is commonly used in various applications, including file encryption tools.

• Symmetric Encryption: This type of encryption uses the same key for both encryption and decryption. The security of the encrypted data depends on keeping this key secret.

• Hash Functions: A hash function takes an input and produces a fixed-size output (the hash). While hash functions are not inherently designed for encryption, they are often used to create message authentication codes or derive keys.

• Random Salt: Salt is random data added to a cryptographic process to make it more resistant to attacks like brute-force or dictionary attacks. It ensures that even if the same data is encrypted multiple times, the resulting encrypted outputs are different.
