Indicated whether this Cipher instance uses an Authenticated Encryption mode.
Parses a given string as a blob that contains configuration for OpenSSL.
If the source of the IO is a file, then consider using parse_config.
Parse the YAML document contained in yaml. Events will be called on the handler set on the parser instance.
See Psych::Parser and Psych::Parser#handler
Another entry point for the parser. If you use this method, you must implement RECEIVER#METHOD_ID method.
RECEIVER#METHOD_ID is a method to get next token. It must ‘yield’ the token, which format is [TOKEN-SYMBOL, VALUE].
Starts the parser. init is a data accumulator and is passed to the next event handler (as of Enumerable#inject).
returns the timestamp as a time object.
ancillarydata should be one of following type:
SOL_SOCKET/SCM_TIMESTAMP (microsecond) GNU/Linux, FreeBSD, NetBSD, OpenBSD, Solaris, MacOS X
SOL_SOCKET/SCM_TIMESTAMPNS (nanosecond) GNU/Linux
SOL_SOCKET/SCM_BINTIME (2**(-64) second) FreeBSD
Addrinfo.udp(“127.0.0.1”, 0).bind {|s1|

}
Changes the parameters of the deflate stream to allow changes between different types of data that require different types of compression. Any unprocessed data is flushed before changing the params.
See Zlib::Deflate.new for a description of level and strategy.
Returns last modification time recorded in the gzip file header.
Specify the modification time (mtime) in the gzip header. Using an Integer.
Setting the mtime in the gzip header does not effect the mtime of the file generated. Different utilities that expand the gzipped files may use the mtime header. For example the gunzip utility can use the ‘-N` flag which will set the resultant file’s mtime to the value in the header. By default many tools will set the mtime of the expanded file to the mtime of the gzipped file, not the mtime in the header.
If you do not set an mtime, the default value will be the time when compression started. Setting a value of 0 indicates no time stamp is available.
Returns the last access time for this file as an object of class Time.
File.stat("testfile").atime #=> Wed Dec 31 18:00:00 CST 1969
Returns the modification time of stat.
File.stat("testfile").mtime #=> Wed Apr 09 08:53:14 CDT 2003
Returns the change time for stat (that is, the time directory information about the file was changed, not the file itself).
Note that on Windows (NTFS), returns creation time (birth time).
File.stat("testfile").ctime #=> Wed Apr 09 08:53:14 CDT 2003
Returns true if stat has its sticky bit set, false if it doesn’t or if the operating system doesn’t support this feature.
File.stat("testfile").sticky? #=> false
Extensions to build when installing the gem, specifically the paths to extconf.rb-style files used to compile extensions.
These files will be run when the gem is installed, causing the C (or whatever) code to be compiled on the user’s machine.
Usage:
spec.extensions << 'ext/rmagic/extconf.rb'
See Gem::Ext::Builder for information about writing extensions for gems.
Activate this spec, registering it as a loaded spec and adding it’s lib paths to $LOAD_PATH. Returns true if the spec was activated, false if it was previously activated. Freaks out if there are conflicts upon activation.
Sets extensions to extensions, ensuring it is an array. Don’t use this, push onto the array instead.
Set the version to version, potentially also setting required_rubygems_version if version indicates it is a prerelease.
Parse obj, returning an [op, version] pair. obj can be a String or a Gem::Version.
If obj is a String, it can be either a full requirement specification, like ">= 1.2", or a simple version number, like "1.2".
parse("> 1.0") # => [">", Gem::Version.new("1.0")] parse("1.0") # => ["=", Gem::Version.new("1.0")] parse(Gem::Version.new("1.0")) # => ["=, Gem::Version.new("1.0")]
Turns on net/http 1.2 (Ruby 1.8) features. Defaults to ON in Ruby 1.8 or later.
Creates a new Net::HTTP object, then additionally opens the TCP connection and HTTP session.
Arguments are the following:
hostname or IP address of the server
port of the server
address of proxy
port of proxy
user of proxy
pass of proxy
optional hash
opt sets following values by its accessor. The keys are ca_file, ca_path, cert, cert_store, ciphers, close_on_empty_response, key, open_timeout, read_timeout, write_timeout, ssl_timeout, ssl_version, use_ssl, verify_callback, verify_depth and verify_mode. If you set :use_ssl as true, you can use https and default value of verify_mode is set as OpenSSL::SSL::VERIFY_PEER.
If the optional block is given, the newly created Net::HTTP object is passed to it and closed when the block finishes. In this case, the return value of this method is the return value of the block. If no block is given, the return value of this method is the newly created Net::HTTP object itself, and the caller is responsible for closing it upon completion using the finish() method.
Returns true if the HTTP session has been started.
Opens a TCP connection and HTTP session.
When this method is called with a block, it passes the Net::HTTP object to the block, and closes the TCP connection and HTTP session after the block has been executed.
When called with a block, it returns the return value of the block; otherwise, it returns self.
Parse a raw cookie string into a hash of cookie-name=>Cookie pairs.
cookies = CGI::Cookie.parse("raw_cookie_string") # { "name1" => cookie1, "name2" => cookie2, ... }
