CyberChef

CyberChef is a versatile, browser-based application designed to simplify data manipulation and analysis. It offers a wide range of operations, including encoding and decoding, data transformation, cryptographic functions, and network analysis. Users can perform tasks such as Base64 encoding, URL encoding, hexadecimal conversion, and HTML entity encoding. Additionally, CyberChef supports various data transformations like string manipulation, search and replace, and regular expressions.

The app also provides robust cryptographic capabilities, allowing users to calculate hashes (MD5, SHA1, SHA256, SHA512), perform symmetric and asymmetric encryption (AES, DES, RSA), derive keys from passwords, and create digital signatures. For network analysis, CyberChef supports IP address conversion, DNS lookups, and PCAP parsing.

One of CyberChef's most powerful features is its ability to create custom recipes. Users can chain multiple operations together to automate repetitive tasks, making it an efficient tool for both beginners and experienced professionals. All processing occurs client-side, ensuring data privacy and security. This makes CyberChef an excellent choice for tasks like decoding obfuscated data, analyzing network traffic, and exploring cryptographic techniques. Its intuitive interface and visual feedback make it accessible to a wide range of users, from security experts to students.
