    Proxyee

    Proxyee

    HTTP proxy server,support HTTPS & websocket

    Proxyee is a JAVA-written HTTP proxy server library that supports HTTP, HTTPS, and WebSocket protocols, and supports MITM (Man-in-the-middle), which can capture and tamper with HTTP, and HTTPS packets. The CA certificate (src/resources/ca.crt) from the project needs to be imported to a trusted root certificate authority. The CA certificate (src/resources/ca.crt) from the project needs to be imported to a trusted root certificate authority. You can use the CertDownIntercept interceptor to enable the web certificate download feature.

    Boulder

    Boulder

    An ACME-based certificate authority, written in Go

    ...The Registration Authority can live without Internet connectivity, but still needs to talk to the Web Front End and Validation Authority. The Certificate Authority need only receive instructions from the Registration Authority. All components talk to the SA for storage. Internally, the logic of the system is based around five types of objects: accounts, authorizations, challenges, orders (for ACME v2) and certificates.

    A transparent, highly scalable and cryptographically verifiable data

    ...The system is designed for horizontal scale with gRPC APIs, enabling multiple frontends and sequencers to operate over a shared backend. Common use cases include certificate transparency, package registries, and audit logs where public verifiability or tamper evidence is required. Trillian exposes both “log” and “map” primitives so developers can choose between append-only timelines or verifiable dictionaries depending on their data model. By making verification independent of trust in the operator, trillian helps build systems that are auditable by external parties.

    A simple SSL/TLS proxy with mutual authentication

    Ghostunnel is a simple TLS proxy with mutual authentication support for securing non-TLS backend applications. Ghostunnel supports two modes, client mode and server mode. Ghostunnel in server mode runs in front of a backend server and accepts TLS-secured connections, which are then proxied to the (insecure) backend. A backend can be a TCP domain/port or a UNIX domain socket. Ghostunnel in client mode accepts (insecure) connections through a TCP or UNIX domain socket and proxies them to a...

What exactly does this mean? In short, it simply has a lot of potential, that can be used in many use case scenarios. Modlishka was written as an attempt to overcome standard reverse proxy limitations and as a personal challenge to see what is possible with sufficient motivation and a bit of extra research time. ...
