sslscan v1.11.13 releases: tests SSL/TLS enabled services to discover supported cipher suites

sslscan tests SSL/TLS enabled services to discover supported cipher suites. This is a fork of ioerror’s version of sslscan. Changes are as follows:

  • Highlight SSLv2 and SSLv3 ciphers in output.
  • Highlight CBC ciphers on SSLv3 (POODLE).
  • Highlight 3DES and RC4 ciphers in output.
  • Highlight PFS+GCM ciphers as good in output.
  • Highlight NULL (0 bit), weak (<40 bit) and medium (40 < n <= 56) ciphers in output.
  • Highlight anonymous (ADH and AECDH) ciphers in output (purple).
  • Hide certificate information by default (display with --get-certificate).
  • Hide rejected ciphers by default (display with --failed).
  • Added TLSv1.1 and TLSv1.2 support (merged from twwbond/sslscan).
  • Compiles if OpenSSL does not support SSLv2 ciphers (merged from digineo/sslscan).
  • Supports IPv6 hostnames (can be forced with --ipv6).
  • Check for TLS compression (CRIME, disable with --no-compression).
  • Disable cipher suite checking --no-ciphersuites.
  • Disable coloured output --no-colour.
  • Removed undocumented -p output option.
  • Added check for OpenSSL HeartBleed (CVE-2014-0160, disable with --no-heartbleed).
  • Flag certificates signed with MD5 or SHA-1, or with short (<2048 bit) RSA keys.
  • Support scanning RDP servers with --rdp (credit skettler).
  • Added option to specify socket timeout.
  • Added option for static compilation (credit dmke).
  • Added --sleep option to pause between requests.
  • Disable output for anything than specified checks --no-preferred.
  • Determine the list of CAs acceptable for client certificates --show-client-cas.
  • Experimental build support on OSX (credit MikeSchroll).
  • Flag some self-signed SSL certificates.
  • Experimental Windows support (credit jtesta).
  • Display EC curve names and DHE key lengths with OpenSSL >= 1.0.2 --no-cipher-details.
  • Flag weak DHE keys with OpenSSL >= 1.0.2 --cipher-details.
  • Flag expired certificates.
  • Flag TLSv1.0 ciphers in output as weak.
  • Experimental OSX support (static building only).
  • Support for scanning PostgreSQL servers (credit nuxi).
  • Check for TLS Fallback SCSV support.
  • Added StartTLS support for LDAP --starttls-ldap.
  • Added SNI support --sni-name (credit Ken).
  • Support STARTTLS for MySQL (credit bk2017).
