O-Saft - check for SSL connection, certificate and ciphers(this text to make crawlers happy;-)
Lab big.jpg

O-Saft

OWASP SSL advanced forensic tool / OWASP SSL audit for testers

O-Saft is an easy to use tool to show informations about SSL certificate and tests the SSL connection according given list of ciphers and various SSL configurations.

It's designed to be used by penetration testers, security auditors or server administrators. The idea is to show the important informations or the special checks with a simple call of the tool. However, it provides a wide range of options so that it can be used for comprehensive and special checks by experienced people.

O-Saft is a command-line tool, so it can be used offline and in closed environments. However, it can simply be turned into an online CGI-tool (please read documentation first).

Introduction

Quick Installation
  • Download and unpack o-saft.tgz (Stable Release)
  • to run o-saft: Ensure that following perl modules (and their dependencies) are installed
      IO::Socket::INET, IO::Socket::SSL, Net::SSLeay
      Net::SSLinfo, Net::SSLhello (which are part of the tarball)
  • read and (re-)move o-saft-README
  • Show help
o-saft --help=commands
o-saft --help
  • Start
o-saft +info your.tld
o-saft +check your.tld
o-saft +quick your.tld
o-saft +cipherall your.tld
o-saft +cipherall --starttls=pop3 pop3.your.tld:110
  • to run the optional checkAllCiphers (tiny program to check solely ciphers, like command '+cipherall'): It usually does not need any perl module to be additionally installed
      Socket (should be part of your perl installation)
      Net::SSLhello (which is part of the tarball)
      NET::DNS (only needed, if option '--mx' is used)
  • Start
checkAllCiphers your.tld
checkAllCiphers --starttls=pop3 pop3.your.tld:110
checkAllCiphers --mx your.tld:25 --starttls=smtp
  • Simple GUI
o-saft.tcl
o-saft.tcl your.tld

Description

The main idea is to have a tool which works on common platforms and can simply be automated.

In a Nutshell
  • show SSL connection details
  • show certificate details
  • check for supported ciphers
  • check for ciphers provided in your own libssl.so and libcrypt.so
  • check for ciphers without any dependency to a library (+cipherall)
  • checks the server's priority for ciphers (+cipherall)
  • check for special HTTP(S) support (like SNI, HSTS, certificate pinning)
  • check for protections against attacks (BEAST, CRIME, FREAK, Heartbleed, Lucky 13, POODLE, RC4 Bias, ...)
  • may check for a single attribute
  • may check multiple targets at once
  • can be scripted (headless or as CGI)
  • should work on any platform (just needs perl, openssl optional)
  • scoring for all checks (still to be improved in many ways ;-)
  • output format can be customized
  • various trace and debug options to hunt unusual connection problems
  • +cipherall: supports STARTTLS for various protocols like (SMTP, POP3, IMAP, LDAP, RDP, XMPP, IRC (experimental) ...),
      slows down to prevent blockades of requests due to too much connections (supported for some protocols like SMTP)
  • check of STARTTLS/SMTP for all servers of a MX Resource Record (e.g. checkAllCiphers --mx your.tld:25 --starttls=smtp)

New Features of Test Version

Quick Installation (test version)
  • Download and unpack: master.zip
  • Start INSTALL-devel.sh
  • Enjoy new functionality:
  • supports now STARTTLS and Proxy for all commands, e.g.
o-saft +info mail.tld:25 --starttls
  • '+cipherall (+cipherraw)', checkAllCiphers.pl: Fixed a Bug in SNI

What is O-Saft?

O-Saft provides:

  • SSL connection details
  • certificate details
  • full cipher check
  • special HTTP(s) checks
  • check for SSL vulnerabilities
  • can be scripted
  • platfrom independent
  • customizable output
  • supports STARTTLS (+cipherall)

FAQs
  • Where can I get missing Perl-Modules?
    This depends on your OS and Perl installation, but just try 'cpan <Module-Name>', e.g. 'cpan Net:DNS'
  • I am connected to the internet via a Proxy
    open the cpan-shell using 'cpan' and configure your proxy settings: 'o conf init /proxy/'
  • I can not download the requested files (the proxy needs authentication)
    run 'cpan <Module-Name>' several times, read the error messages and copy the requested files manually to the paths (without any additional temporary extension of the name),
    e.g. http://www.cpan.org/authors/01mailrc.txt.gz => <Your Program Path>/cpan/sources/authors/01mailrc.txt.gz
  • I get the Error "invalid SSL_version specified at .../perl/vendor/lib/IO/Socket/SSL.pm line ..."
  • add options '--notlsv13 --nodtlsv1', e.g. perl o-saft.pl +info your.tld --notlsv13 --nodtlsv1

Some of the ways you can help:

  • Quality assurance: simply test O-Saft and report defects and strange responses of servers
  • Give some ideas how to implement scoring
  • Need help in implementing
  • authentication for proxies (BASIC, NTLM)
  • to check the size of Diffie Hellmann Parameters
  • check for more SSL/TLS-Extensions (including obsolete ones)
  • check for more vulnerabilities
  • check the full certificate chain
