SSLSCAN(1) General Commands Manual SSLSCAN(1) NAME sslscan - Fast SSL/TLS scanner SYNOPSIS sslscan [options] [host:port | host] DESCRIPTION This manual page documents briefly the sslscan command sslscan queries SSL/TLS services, such as HTTPS, in order to determine the ciphers that are supported. SSLScan is designed to be easy, lean and fast. The output includes pre- ferred ciphers of the SSL/TLS service, and text and XML output formats are supported. It is TLS SNI aware when used with a supported version of OpenSSL. Output is colour coded to indicate security issues. Colours are as fol- lows: Red Background NULL cipher (no encryption) Red Broken cipher (<= 40 bit), broken protocol (SSLv2 or SSLv3) or broken certificate signing algorithm (MD5) Yellow Weak cipher (<= 56 bit or RC4) or weak certificate signing algorithm (SHA-1) Purple Anonymous cipher (ADH or AECDH) OPTIONS --help Show summary of options --version Show version of program --targets=<file> A file containing a list of hosts to check. Hosts can be sup- plied with ports (i.e. host:port). One target per line --sni-name=<name> Use a different hostname for SNI --ipv4, -4 Force IPv4 DNS resolution. Default is to try IPv4, and if that fails then fall back to IPv6. --ipv6, -6 Force IPv6 DNS resolution. Default is to try IPv4, and if that fails then fall back to IPv6. --show-certificate Display certificate information. --no-check-certificate Don't flag certificates signed with weak algorithms (MD5 and SHA-1) or short (<2048 bit) RSA keys --show-client-cas Show a list of CAs that the server allows for client authentica- tion. Will be blank for IIS/Schannel servers. --show-ciphers Show a complete list of ciphers supported by sslscan --show-cipher-ids Print the hexadecimal cipher IDs --show-times Show the time taken for each handshake in milliseconds. Note that only a single request is made with each cipher, and that the size of the ClientHello is not constant, so this should not be used for proper benchmarking or performance testing. You might want to also use --no-cipher-details to make the out- put a bit clearer. --ssl2 Only check SSLv2 ciphers Note that this option may not be available if system OpenSSL does not support SSLv2. Either build OpenSSL statically or re- build your system OpenSSL with SSLv2 support. See the readme for further details. --ssl3 Only check SSLv3 ciphers Note that this option may not be available if system OpenSSL does not support SSLv3. Either build OpenSSL statically or re- build your system OpenSSL with SSLv3 support. See the readme for further details. --tls10 Only check TLS 1.0 ciphers --tls11 Only check TLS 1.1 ciphers --tls12 Only check TLS 1.2 ciphers --tlsall Only check TLS ciphers (versions 1.0, 1.1 and 1.2) --ocsp Display OCSP status --pk=<file> A file containing the private key or a PKCS#12 file containing a private key/certificate pair (as produced by MSIE and Netscape) --pkpass=<password> The password for the private key or PKCS#12 file --certs=<file> A file containing PEM/ASN1 formatted client certificates --no-ciphersuites Do not scan for supported ciphersuites. --no-renegotiation Do not check for secure TLS renegotiation --no-fallback Do not check for TLS Fallback Signaling Cipher Suite Value (fallback) --no-compression Do not check for TLS compression (CRIME) --no-heartbleed Do not check for OpenSSL Heartbleed (CVE-2014-0160) --starttls-ftp STARTTLS setup for FTP --starttls-irc STARTTLS setup for IRC --starttls-imap STARTTLS setup for IMAP --starttls-ldap STARTTLS setup for LDAP --starttls-pop3 STARTTLS setup for POP3 --starttls-smtp STARTTLS setup for SMTP Note that some servers hang when we try to use SSLv3 ciphers over STARTTLS. If you scan hangs, try using the --tlsall option. --starttls-psql STARTTLS setup for PostgreSQL --starttls-mysql STARTTLS setup for MySQL --starttls-xmpp STARTTLS setup for XMPP --xmpp-server Perform a server-to-server XMPP connection. Try this if --start- tls-xmpp is failing. --rdp Send RDP preamble before starting scan. --http Makes a HTTP request after a successful connection and returns the server response code --no-cipher-details Hide NIST EC curve name and EDH/RSA key length. Requires OpenSSL >= 1.0.2 (so if you distro doesn't ship this, you'll need to statically build sslscan). --bugs Enables workarounds for SSL bugs --timeout=<sec> Set socket timeout. Useful for hosts that fail to respond to ci- phers they don't understand. Default is 3s. --sleep=<msec> Pause between connections. Useful on STARTTLS SMTP services, or anything else that's performing rate limiting. Default is dis- abled. --xml=<file> Output results to an XML file. - can be used to mean stdout. --no-colour Disable coloured output.
