OpenSSL::OCSP::CertificateId

An OpenSSL::OCSP::CertificateId identifies a certificate to the CA so that a status check can be performed.

OpenSSL::X509::CertificateError

No documentation available

A Gem::Security::Policy object encapsulates the settings for verifying signed gem files. This is the base class. You can either declare an instance of this or use one of the preset security policies in Gem::Security::Policies.

Gem::Resolver::Conflict

Used internally to indicate that a dependency conflicted with a spec that would be activated.

SyntaxSuggest::Capture::FallingIndentLines

Shows the context around code provided by “falling” indentation

If this is the original code lines:

class OH
  def hello
    it "foo" do
  end
end

And this is the line that is captured

it "foo" do

It will yield its surrounding context:

class OH
  def hello
  end
end

Example:

FallingIndentLines.new(
    block: block,
    code_lines: @code_lines
).call do |line|
  @lines_to_output << line
end

Enumerator::Producer

Producer

Encoding::CompatibilityError

Raised by Encoding and String methods when the source encoding is incompatible with the target encoding.

JSON::GenericObject

No documentation available

OpenSSL::OpenSSLError

Generic error, common for all classes under OpenSSL module

OpenSSL::HMACError

Document-class: OpenSSL::HMAC

OpenSSL::HMAC allows computing Hash-based Message Authentication Code (HMAC). It is a type of message authentication code (MAC) involving a hash function in combination with a key. HMAC can be used to verify the integrity of a message as well as the authenticity.

OpenSSL::HMAC has a similar interface to OpenSSL::Digest.

HMAC-SHA256 using one-shot interface

key = "key"
data = "message-to-be-authenticated"
mac = OpenSSL::HMAC.hexdigest("SHA256", key, data)
#=> "cddb0db23f469c8bf072b21fd837149bd6ace9ab771cceef14c9e517cc93282e"

HMAC-SHA256 using incremental interface

data1 = File.binread("file1")
data2 = File.binread("file2")
key = "key"
hmac = OpenSSL::HMAC.new(key, 'SHA256')
hmac << data1
hmac << data2
mac = hmac.digest

Psych::AliasesNotEnabled

Subclasses ‘BadAlias` for backwards compatibility

Socket::UDPSource

UDP/IP address information used by Socket.udp_server_loop.

Zlib::NeedDict

Subclass of Zlib::Error

When zlib returns a Z_NEED_DICT if a preset dictionary is needed at this point.

Used by Zlib::Inflate.inflate and Zlib.inflate

RubyVM::InstructionSequence

The InstructionSequence class represents a compiled sequence of instructions for the Virtual Machine used in MRI. Not all implementations of Ruby may implement this class, and for the implementations that implement it, the methods defined and behavior of the methods can change in any version.

With it, you can get a handle to the instructions that make up a method or a proc, compile strings of Ruby code down to VM instructions, and disassemble instruction sequences to strings for easy inspection. It is mostly useful if you want to learn how YARV works, but it also lets you control various settings for the Ruby iseq compiler.

You can find the source for the VM instructions in insns.def in the Ruby source.

The instruction sequence results will almost certainly change as Ruby changes, so example output in this documentation may be different from what you see.

Of course, this class is MRI specific.
