This article demonstrates how to implement common password‑encryption techniques in Python—including plain MD5, MD5 with salts, SHA1, SHA256, and HMAC—by wrapping them in a reusable class and showing sample code and output for each method.
This article introduces common encryption methods—including Base64, MD5, SHA‑1, HMAC, DES, AES, and RSA—explains their principles, and provides complete Python code examples for encoding, decoding, and key handling, enabling readers to implement secure data transformations in their own projects.
This article walks through the inner workings of Git, explaining how initializing a repository creates the .git structure, how objects, blobs, and SHA‑1 hashes store file contents, the roles of the working directory, index, and commit objects, and how branches, HEAD, and remote connections operate together to manage version history.
This article explores the original 1,000‑line Git source from its first commit, showing how to obtain, compile, and analyze the core commands and objects—init‑db, update‑cache, cat‑file, show‑diff, write‑tree, read‑tree, commit‑tree—while explaining Git’s design principles, storage layout, SHA‑1 naming, and the limitations of the initial implementation.
