AQUATONE
A tool for domain flyovers
Aquatone is a tool for visual inspection of websites across a large amount of hosts and is convenient for quickly gaining an overview of HTTP-based attack surface. Aquatone is designed to be as easy to use as possible and to integrate with your existing toolset with no or minimal glue. Aquatone is started by piping output of a command into the tool. It doesn't really care how the piped data looks as URLs, domains, and IP addresses will be extracted with regular expression pattern matching. This means that you can pretty much give it output of any tool you use for host discovery. Aquatone is now completely focused on screenshotting and reporting. I know a lot of people used Aquatone for its DNS enumeration capabilities and it was definitely very good at that when it was released. Now other tools are doing a much better job of this, so I decided to leave it out of the new Aquatone, and instead make it easy to use it with your tool of choice. -

CFSSL
Cloudflare's PKI and TLS toolkit
CFSSL is CloudFlare's PKI/TLS swiss army knife. It is both a command line tool and an HTTP API server for signing, verifying, and bundling TLS certificates. It requires Go 1.12+ to build. Note that certain linux distributions have certain algorithms removed (RHEL-based distributions in particular), so the golang from the official repositories will not work. Users of these distributions should install go manually to install CFSSL. You can set the GOOS and GOARCH environment variables to have Go cross compile for alternative platforms; however, cfssl requires cgo, and cgo requires a working compiler toolchain for the target platform. The csr is the client's certificate request. The -ca and -ca-key flags are the CA's certificate and private key, respectively. By default, they are ca.pem and ca_key.pem. The -hostname is a comma separated hostname list that overrides the DNS names and IP address in the certificate SAN extension. -

SafeLine
Serve as a reverse proxy to protect your web services from attacks
SafeLine is a self-hosted WAF(Web Application Firewall) to protect your web apps from attacks and exploits. A web application firewall helps protect web apps by filtering and monitoring HTTP traffic between a web application and the Internet. It typically protects web apps from attacks such as SQL injection, XSS, code injection, os command injection, CRLF injection, LDAP injection, XPath injection, RCE, XXE, SSRF, path traversal, backdoor, brute force, HTTP-flood, bot abuse, among others. By deploying a WAF in front of a web application, a shield is placed between the web application and the Internet. While a proxy server protects a client machine’s identity by using an intermediary, a WAF is a type of reverse-proxy, protecting the server from exposure by having clients pass through the WAF before reaching the server. A WAF protects your web apps by filtering, monitoring, and blocking any malicious HTTP/S traffic traveling to the web application. -

BadUSB
Flipper Zero badusb payload library
This project explores USB device emulation attacks—commonly called BadUSB—by demonstrating how commodity USB hardware can impersonate keyboards, network adapters, or storage devices to perform scripted actions on a host. It typically contains firmware examples, payloads, and explanations showing how a device presenting as a Human Interface Device (HID) can inject keystrokes, open shells, or orchestrate data exfiltration when plugged into a machine. The codebase is frequently intended for security research and defensive testing: defenders and red teams use it to validate endpoint controls, USB whitelisting, and user training. Due to the dual-use nature of such techniques, responsible repositories emphasize lab-only experiments, consent-based testing, and mitigations like disabling autorun, enforcing device policies, and using endpoint detection. -

Ciphey
Decrypt encryptions without knowing the key or cipher
Fully automated decryption/decoding/cracking tool using natural language processing & artificial intelligence, along with some common sense. You don't know, you just know it's possibly encrypted. Ciphey will figure it out for you. Ciphey can solve most things in 3 seconds or less. Ciphey aims to be a tool to automate a lot of decryptions & decodings such as multiple base encodings, classical ciphers, hashes or more advanced cryptography. If you don't know much about cryptography, or you want to quickly check the ciphertext before working on it yourself, Ciphey is for you. The technical part. Ciphey uses a custom-built artificial intelligence module (AuSearch) with a Cipher Detection Interface to approximate what something is encrypted with. And then a custom-built, customizable natural language processing Language Checker Interface, which can detect when the given text becomes plaintext. -

Clair
Vulnerability Static Analysis for Containers
Clair is an application for parsing image contents and reporting vulnerabilities affecting the contents. This is done via static analysis and not at runtime. Clair v4 utilizes the ClairCore library as its engine for examining contents and reporting vulnerabilities. At a high level you can consider Clair a service wrapper to the functionality provided in the ClairCore library. The main branch may be in an unstable or even broken state during development. Please use releases instead of the main branch in order to get stable binaries. Clair is an open source project for the static analysis of vulnerabilities in application containers (currently including OCI and docker). Clients use the Clair API to index their container images and can then match it against known vulnerabilities. Our goal is to enable a more transparent view of the security of container-based infrastructure. Thus, the project was named Clair after the French term which translates to clear, bright, transparent. -

FHEVM
Integrate FHE with blockchain applications
FHEVM is a framework built by Zama to enable confidential smart contracts on EVM-compatible blockchains using Fully Homomorphic Encryption (FHE). It lets developers write Solidity contracts that handle encrypted inputs, encrypted state, arithmetic and logical operations on encrypted types, while maintaining privacy (data always encrypted), composability (encrypted state works alongside public state), and security (via threshold decryption, KMS, etc). The framework includes on-chain and off-chain components (contracts, coprocessors, gateway, utilities) to orchestrate the whole encrypted data pipeline. -

File system notifications for Go
Cross-platform file system notifications for Go
fsnotify utilizes golang.org/x/sys rather than syscall from the standard library. Ensure you have the latest version installed. fsnotify is a fork of howeyc/fsnotify with a new API as of v1.0. The API is based on this design document. All releases are tagged based on Semantic Versioning. Further API changes are planned, and will be tagged with a new major revision number. Go 1.6 supports dependencies located in the vendor/ folder. Unless you are creating a library, it is recommended that you copy fsnotify into vendor/github.com/fsnotify/fsnotify within your project, and likewise for golang.org/x/sys. fsnotify requires support from underlying OS to work. The current NFS protocol does not provide network level support for file notifications. -
