    ClamAV

    ClamAV

    Antivirus engine for detecting trojans, viruses and malware

    ...Originally designed for Unix environments and email security, it has evolved into a flexible antimalware toolkit capable of identifying millions of viruses, worms, trojans, and other threats. The software includes a command-line scanner, an automatically updating signature database, and a scalable multi-threaded daemon that enables high-performance scanning in production environments. ClamAV is widely used in mail gateways, file servers, and security pipelines because it can inspect compressed archives, common document formats, and executable files. Its bytecode signature system allows advanced detection logic while ensuring signatures are trusted and securely distributed.

    ...The code demonstrates how scripted traffic might be generated and measured, highlighting the kinds of heuristics a platform could use to validate or discount views. It is often used to study rate limits, signature schemes, request patterns, and the fragility of naïve automation. Because it touches on automation against a third-party service, responsible use and adherence to platform terms are emphasized; using such tools to manipulate metrics or violate policies is unethical and can be unlawful. From a security research perspective, understanding these patterns helps both defenders and platform engineers improve abuse detection. ...

    GopenPGP V3

    GopenPGP V3

    A high-level OpenPGP library

    GopenPGP V3 is a high-level OpenPGP cryptographic library developed by ProtonMail that provides a user-friendly API for common encryption and signing operations in Go, abstracting the complexity of the underlying OpenPGP standards and golang crypto primitives. This library lets developers perform key generation, message encryption and decryption, digital signing, and signature verification with straightforward functions that hide much of the boilerplate and nuance typically required when working directly with OpenPGP implementations. Built on top of a forked version of the Go crypto library, gopenpgp supports current OpenPGP RFC standards and includes examples for working with password-based encryption and PGP keys, as well as detached and inline signatures. ...
