This toolkit is useful for automatic auditing certificates and retrieving information from them. It can be used for monitoring certificates. These certificates could be stored in a local file or remotely on a system. In the latter case, the tool will be able to connect to the system and retrieve the related information.

When using SSL Labs, you may have had chain anchor issues when verifying a website or web application. The sslmerge tool helps to merge the domain certificate, intermediate certificate, and root certificates.

The tls-ca-manage is a certificate authority management tool written in shell script. It can be used to manage certificates for TLS/SSL configurations.

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.

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

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.

SSLsplit is a tool for man-in-the-middle attacks against SSL/TLS encrypted network connections. Connections are transparently intercepted through a network address translation engine and redirected to SSLsplit. SSLsplit terminates SSL/TLS and initiates a new SSL/TLS connection to the original destination address, while logging all data transmitted. SSLsplit is intended to be useful for network forensics and penetration testing.

SSLsplit supports plain TCP, plain SSL, HTTP and HTTPS connections over both IPv4 and IPv6. For SSL and HTTPS connections, SSLsplit generates and signs forged X509v3 certificates on-the-fly, based on the original server certificate subject DN and subjectAltName extension. SSLsplit fully supports Server Name Indication (SNI) and is able to work with RSA, DSA and ECDSA keys and DHE and ECDHE cipher suites. Depending on the version of OpenSSL, SSLsplit supports SSL 3.0, TLS 1.0, TLS 1.1 and TLS 1.2, and optionally SSL 2.0 as well. SSLsplit can also use existing certificates of which the private key is available, instead of generating forged ones. SSLsplit supports NULL-prefix CN certificates and can deny OCSP requests in a generic way. For HTTP and HTTPS connections, SSLsplit removes response headers for HPKP in order to prevent public key pinning, for HSTS to allow the user to accept untrusted certificates, and Alternate Protocols to prevent switching to QUIC/SPDY. As an experimental feature, SSLsplit supports STARTTLS mechanisms in a generic manner.

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

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

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.

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.
