SOPS
Simple and flexible tool for managing secrets
sops is an editor of encrypted files that supports YAML, JSON, ENV, INI and BINARY formats and encrypts with AWS KMS, GCP KMS, Azure Key Vault, age, and PGP. For the adventurous, unstable features are available in the develop branch, which you can install from source. To use sops as a library, take a look at the decrypt package. We rewrote Sops in Go to solve a number of deployment issues, but the Python branch still exists under python-sops. We will keep maintaining it for a while, and you can still pip install sops, but we strongly recommend you use the Go version instead. If you're using AWS KMS, create one or multiple master keys in the IAM console and export them, comma separated, in the SOPS_KMS_ARN env variable. It is recommended to use at least two master keys in different regions. If you want to use PGP, export the fingerprints of the public keys, comma separated, in the SOPS_PGP_FP env variable. -

PhoneInfoga
Information gathering framework for phone numbers
PhoneInfoga is an open-source intelligence framework focused on gathering and analyzing information related to international phone numbers. The tool aggregates data from multiple scanners and external services to provide contextual intelligence such as country, carrier, line type, and potential VoIP provider details. It is designed primarily for investigators, analysts, and security researchers who need structured phone-number reconnaissance rather than real-time tracking. PhoneInfoga intentionally avoids automation of invasive actions and instead assists manual investigations by correlating publicly available data. The platform includes both a command-line interface and a web client backed by a REST API, making it suitable for integration into larger investigative workflows. Because it relies heavily on external data sources, its effectiveness depends on proper configuration of scanners and APIs. -

mkcert
Zero-config tool to make locally trusted development certificates
mkcert is a simple tool for making locally-trusted development certificates. It requires no configuration. Using certificates from real certificate authorities (CAs) for development can be dangerous or impossible (for hosts like example.test, localhost or 127.0.0.1), but self-signed certificates cause trust errors. Managing your own CA is the best solution, but usually involves arcane commands, specialized knowledge and manual steps. mkcert automatically creates and installs a local CA in the system root store, and generates locally-trusted certificates. mkcert does not automatically configure servers to use the certificates, though, that's up to you. The CA certificate and its key are stored in an application data folder in the user's home. You usually don't have to worry about it, as the installation is automated, but the location is printed by mkcert -CAROOT. -

gopass
The slightly more awesome standard unix password manager for teams
gopass is a simple but powerful password manager for your terminal. Manage your credentials with ease. In a globally distributed team, on multiple devices or fully offline on an air-gapped machine. By default your credentials are encrypted with GPG and versioned in git. This can be customized easily. The primary interface is the command line, making it an excellent choice for CLI fans, CI/CD systems or anything you can hook it up with. Gopass can also integrate with your browser so you can largely avoid the command line - if you want. gopass can operate without any dependencies but most users will use it with gpg and git. An external editor is required to use gopass edit. The same user experience on Linux, MacOS, *BSD or Windows. Built from our experience working in distributed development teams. -

AWS Vault
A vault for securely storing and accessing AWS credentials
AWS Vault is a tool to securely store and access AWS credentials in a development environment. AWS Vault stores IAM credentials in your operating system's secure keystore and then generates temporary credentials from those to expose to your shell and applications. It's designed to be complementary to the AWS CLI tools, and is aware of your profiles and configuration in ~/.aws/config. By default, there is a dedicated Keychain for AWS credentials and Keychain prompts you when credentials are accessed. Beyond the strong storage-at-rest, aws-vault generates short-lived session-based credentials to expose to sub-processes and it encourages you to use the tool to run other tools, rather than exporting credentials to your environment. This means that rogue node.js packages have a harder time obtaining your credentials, and when they do, are limited to the lifetime of the session. -

Brook
Brook is a cross-platform strong encryption and not detectable proxy
Brook is a cross-platform strong encryption and not detectable proxy. Brook's goal is to keep it simple, stupid and not detectable. You can run commands after entering the command-line interface. Usually, everyone uses the command line interface on Linux servers. Of course, Linux also has desktops that can also run GUI. Of course, macOS and Windows also have command-line interfaces, but you may not use them frequently. Usually, the applications opened by double-clicking/clicking on macOS/Windows/iOS/Android are all GUIs. Usually, if you use Brook, you will need a combination of Server and Client, Of course Brook CLI also has many other independent functions. The Brook CLI file is an independent command file, it can be said that there is no concept of installation, just download this file to your computer, run it after granting it executable permissions in the command line interface. -

Gobuster
Directory/File, DNS and VHost busting tool written in Go
Gobuster is a tool used to brute-force. This project is born out of the necessity to have something that didn't have a fat Java GUI (console FTW), something that did not do recursive brute force, something that allowed me to brute force folders and multiple extensions at once, something that compiled to native on multiple platforms, something that was faster than an interpreted script (such as Python), and something that didn't require a runtime. Provides several modes, like the classic directory brute-forcing mode, DNS subdomain brute-forcing mode, the mode that enumerates open S3 buckets and looks for existence and bucket listings, and the virtual host brute-forcing mode (not the same as DNS!). Since this tool is written in Go you need to install the Go language/compiler/etc. Full details of installation and set up can be found on the Go language website. Once installed you have two options. You need at least go 1.16.0 to compile gobuster. -

subfinder
Fast passive subdomain enumeration tool
Subfinder is a high-performance passive subdomain discovery tool built for fast and reliable asset enumeration. It focuses exclusively on collecting valid subdomains from a wide range of passive online sources, prioritizing accuracy and speed over intrusive scanning techniques. The project is widely used in bug bounty hunting, penetration testing, and attack surface mapping because it minimizes noise while producing actionable results. Its modular architecture allows users to enable dozens of data providers through API keys, expanding coverage as needed. Subfinder integrates easily into automation pipelines and CI workflows thanks to its clean command-line design and structured output formats. The tool is intentionally specialized, doing one job extremely well rather than attempting to be an all-in-one scanner. In practice, Subfinder serves as a foundational building block for modern reconnaissance stacks. -

age
A simple, modern and secure encryption tool (and Go library)
age is a security-oriented tool and library by Filo Sottile. age is a simple, modern, secure encryption utility (and Go library) that emphasizes minimal configuration and strong defaults. It provides small explicit keys, no complex options, and is designed for UNIX-style composability; you can pipe into it, integrate it into scripts, etc. It supports a clearly defined format and promotes interoperability across implementations (there are Rust, TypeScript, etc). The project is well-suited for personal data encryption, backup use-cases, scripting encryption workflows, and embedding encryption in tools. Because of its design philosophy, it avoids the bloat of many older encryption utilities while maintaining strong cryptographic hygiene. It’s especially useful for developers or system administrators who want to adopt encryption without learning a multitude of options. -

OWASP Amass
In-depth attack surface mapping and asset discovery
The OWASP Amass Project has developed a tool to help information security professionals perform network mapping of attack surfaces and perform external asset discovery using open source information gathering and active reconnaissance techniques. The Open Web Application Security Project (OWASP) is a nonprofit foundation that works to improve the security of software. All of our projects ,tools, documents, forums, and chapters are free and open to anyone interested in improving application security. The volume argument allows the Amass graph database to persist between executions and output files to be accessed on the host system. The first field (left of the colon) of the volume option is the amass output directory that is external to Docker, while the second field is the path, internal to Docker, where amass will write the output files. -

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. Because it’s designed for broad use, the library also targets go-mobile compatibility, meaning it can support mobile app use cases alongside server and desktop tooling. -

kubelogin
kubectl plugin for Kubernetes OpenID Connect authentication
Kubelogin is designed to run as a client-go credential plugin. When you run kubectl, kubelogin opens the browser and you can log in to the provider. Then kubelogin gets a token from the provider and kubectl accesses Kubernetes APIs with the token. If you install via GitHub releases, you need to put the kubelogin binary on your path under the name kubectl-oidc_login so that the kubectl plugin mechanism can find it when you invoke kubectl oidc-login. The other install methods do this for you. If the cached ID token is valid, kubelogin just returns it. If the cached ID token has expired, kubelogin will refresh the token using the refresh token. If the refresh token has expired, kubelogin will perform re-authentication (you will have to login via browser again). -

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. -
24
Coroot
