SSLsplit alternatives

Sslcaudit is a tool that focuses on the niche of testing SSL/TLS clients.

HTTPS connections use cryptographic functions to provide confidentiality and integrity. It can provide features like domain validation, end-to-end encryption, and a trust chain from certificate authorities down to the end-user. Any flaws can endanger these goals, like the impersonation of a system, man-in-the-middle (MitM) attacks, and website spoofing. This project helps to find flaws and improve the overall security of our internet.

With Lemur you can provide a central portal for developers and administrators to issue TLS certificates with predefined defaults.

Lemur works on CPython 3.5 and uses the Flask framework. Another component it uses is cryptography to handle the creation of the certificates.

Netflix develops on macOS and deploys on Ubuntu servers.

O-Saft is the abbreviation for OWASP SSL advanced forensic tool.

This popular toolkit is used by many systems. It provides options like encryption and hashing of data, integrity testing, and digital certificates and signatures. Many software applications use the toolkit to provide support for these functions. OpenSSL also has a client utility that can be used on the command line to test, decrypt and encrypt data, and create certificates.

SSLMap uses its own SSL engine to avoid any dependencies or limitations with pre-installed libraries.

The tool is of great assistance to quickly perform a security audit and may be used during penetrating testing, or guiding system administrator for system hardening.

Clinker is a tool to test SSL and TLS security for Firefox. It is an addon that shows the used cipher suites, certificates, and shows related security information of the connection itself.

Requirements: Firefox

Pshtt was developed to push organizations, including government departments, to adopt HTTPS across the enterprise.

Key features of testssl.sh include:

• Clear output: you can tell easily whether anything is good or bad
• Ease of installation: It works for Linux, Darwin, FreeBSD, NetBSD and MSYS2/Cygwin out of the box: no need to install or configure something, no gems, CPAN, pip or the like.
• Flexibility: You can test any SSL/TLS enabled and STARTTLS service, not only webservers at port 443
• Toolbox: Several command line options help you to run YOUR test and configure YOUR output
• Reliability: features are tested thoroughly
• Verbosity: If a particular check cannot be performed because of a missing capability on your client side, you'll get a warning
• Privacy: It's only you who sees the result, not a third party
• Freedom: It's 100% open source. You can look at the code, see what's going on and you can change it.

ArpOn protects a system by running as a daemon and guard against a Man in the Middle (MitM) attack due to ARP spoofing, cache poisoning, or an ARP poison routing attack.

The tool works by using three types of inspection to detect a related attack.

• SARPI (Static ARP Inspection), statically configured networks (without DHCP)
• DARPI (Dynamic ARP Inspection), dynamically configured networks (with DHCP)
• HARPI (Hybrid ARP Inspection), statically and dynamically configured networks (with DHCP)

BetterCAP is often used by those who perform penetration testing and security assessments. This tool and framework is in particular useful for attempting man-in-the-middle attacks (MitM).

DNSChef is a DNS proxy that can be used terminate or intercept traffic for DNS traffic. This might be useful during a penetration test or when researching malware and manipulate the actual DNS responses.

This tool performs multiple types of scanning and attacks, which can be useful during penetration tests and security assignments.

This tool would most likely be used to intercept traffic during security assessments. Plaintext passwords and session data can be intercepted with it.

A typical use case for multiplexing is to allow serving several services on one port. Port 443 is commonly used, as that is typically opened on firewalls to allow HTTPS traffic. By multiplexing it, you can also use SSH or other services on the same port.

ZGrab is a stateful application-layer scanner. It works together with ZMap and is also part of the ZMap project. ZGrab is written in Go and supports multiple protocols, including:

• BACNET
• HTTP
• HTTPS
• FTP
• IMAP
• POP3
• Modbus
• Siemens S7
• SMTP
• SSH
• Telnet
• Tridium Fox

Tlsenum is a CLI tool to enumerate TLS protocol and TLS cipher support by a server. The tool lists then the output based on the order of priority. Tlsenum can be used to find the supported protocols and ciphers of a system and determine if it is properly hardened. This information can be useful to system administrators and pentesters doing a security assessment of the system.
