Construct a new OpenSSL BIGNUM object.
If bn is an Integer or OpenSSL::BN, a new instance of OpenSSL::BN representing the same value is returned. See also Integer#to_bn for the short-hand.
If a String is given, the content will be parsed according to base.
stringThe string to be parsed.
baseThe format. Must be one of the following:
0 - MPI format. See the man page BN_mpi2bn(3) for details.
2 - Variable-length and big-endian binary encoding of a positive number.
10 - Decimal number representation, with a leading ‘-’ for a negative number.
16 - Hexadecimal number representation, with a leading ‘-’ for a negative number.
The string must contain a valid cipher name like “aes-256-cbc”.
A list of cipher names is available by calling OpenSSL::Cipher.ciphers.
Creates a Digest instance based on string, which is either the ln (long name) or sn (short name) of a supported digest algorithm. A list of supported algorithms can be obtained by calling OpenSSL::Digest.digests.
If data (a String) is given, it is used as the initial input to the Digest instance, i.e.
digest = OpenSSL::Digest.new('sha256', 'digestdata')
is equivalent to
digest = OpenSSL::Digest.new('sha256') digest.update('digestdata')
Returns an instance of OpenSSL::HMAC set with the key and digest algorithm to be used. The instance represents the initial state of the message authentication code before any data has been processed. To process data with it, use the instance method update with your data as an argument.
key = 'key' instance = OpenSSL::HMAC.new(key, 'SHA1') #=> f42bb0eeb018ebbd4597ae7213711ec60760843f instance.class #=> OpenSSL::HMAC
Two instances can be securely compared with == in constant time:
other_instance = OpenSSL::HMAC.new('key', 'SHA1') #=> f42bb0eeb018ebbd4597ae7213711ec60760843f instance == other_instance #=> true
Creates an instance of OpenSSL::Config from the content of the file specified by filename.
This can be used in contexts like OpenSSL::X509::ExtensionFactory.config=
This can raise IO exceptions based on the access, or availability of the file. A ConfigError exception may be raised depending on the validity of the data being configured.
Many methods in this class aren’t documented.
Creates a new Psych::Parser instance with handler. YAML events will be called on handler. See Psych::Parser for more details.
Create a new scanner
Create a new TreeBuilder instance
Create a new Psych::Emitter that writes to io.
Creates a new Ripper::Filter instance, passes parameters src, filename, and lineno to Ripper::Lexer.new
The lexer is for internal use only.

remote_address is an Addrinfo object.
local_address is an Addrinfo object.
reply_proc is a Proc used to send reply back to the source.
Returns a new Socket::Option object.
sockopt = Socket::Option.new(:INET, :SOCKET, :KEEPALIVE, [1].pack("i")) p sockopt #=> #<Socket::Option: INET SOCKET KEEPALIVE 1>
initialize
Returns OLE event object. The first argument specifies WIN32OLE object. The second argument specifies OLE event name.
ie = WIN32OLE.new('InternetExplorer.Application') ev = WIN32OLE::Event.new(ie, 'DWebBrowserEvents')
