# lighttpd support for SSLv2 and SSLv3 # # Documentation: http://redmine.lighttpd.net/projects/lighttpd/wiki/Docs:SSL # (Following SSL/TLS Deployment Best Practices 1.3 / 17 September 2013 from: # https://www.ssllabs.com/projects/best-practices/index.html) # - BEAST is considered mitigaed on client side now, and new weaknesses have been found in RC4, # so it is strongly advised to disable RC4 ciphers (HIGH doesn't include RC4) # - It is recommended to disable 3DES too (although disabling RC4 and 3DES breaks IE6+8 on Windows XP, # so you might want to support 3DES for now - just remove the '!3DES' parts below). # - The examples below prefer ciphersuites with "Forward Secrecy" (and ECDHE over DHE (alias EDH)), remove '+kEDH +kRSA' # if you don't want that. # - SRP and PSK are not supported anyway, excluding those ('!kSRP !kPSK') just keeps the list smaller (easier to review) # Check your cipher list with: openssl ciphers -v '...' (use single quotes as your shell won't like ! in double quotes) # # If you know you have RSA keys (standard), you can use: #ssl.cipher-list = "aRSA+HIGH !3DES +kEDH +kRSA !kSRP !kPSK" # The more generic version (without the restriction to RSA keys) is #ssl.cipher-list = "HIGH !aNULL !3DES +kEDH +kRSA !kSRP !kPSK" # Make the server prefer the order of the server side cipher suite instead of the client suite. # This option is enabled by default, but only used if ssl.cipher-list is set. # #ssl.honor-cipher-order = "enable" # $SERVER["socket"] == ":443" { ssl.engine = "enable" ## If you have a .crt and a .key file, cat them together into a ## single PEM file: ## $ cat lighttpd.key lighttpd.crt > lighttpd.pem ssl.pemfile = "/etc/lighttpd/server.pem" # ssl.ca-file = "/etc/certs/ca-certificates.crt" $HTTP["useragent"] =~ "MSIE" { server.max-keep-alive-requests = 0 } }
