Constructor Detail

def : LibSSL::SSLMethod = Context.default_method) #

Generates a new TLS server context with sane defaults for a server connection.

Defaults to TLS_method or SSLv23_method (depending on OpenSSL version) which tells OpenSSL to negotiate the TLS or SSL protocol with the remote endpoint.

Don't change the method unless you must restrict a specific protocol to be used (eg: TLSv1.2) and nothing else. You should specify options to disable specific protocols, yet allow to negotiate from various other ones. For example the following snippet will enable the TLSv1, TLSv1.1 and TLSv1.2 protocols but disable the deprecated SSLv2 and SSLv3 protocols:

context =
context.add_options(OpenSSL::SSL::Options::NO_SSL_V2 | OpenSSL::SSL::Options::NO_SSL_V3)

Class Method Detail

def self.insecure(method : LibSSL::SSLMethod = Context.default_method) #

Returns a new TLS server context with only the given method set.

For everything else this uses the defaults of your OpenSSL. Use this only if undoing the defaults that new sets is too much hassle.
