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

This class is the access to openssl’s ENGINE cryptographic module implementation.

Subclasses ‘BadAlias` for backwards compatibility

Raised when OLE query failed.

Subclass of Zlib::Error. This error is raised when the zlib stream is currently in progress.

For example:

inflater = Zlib::Inflate.new
inflater.inflate(compressed) do
  inflater.inflate(compressed) # Raises Zlib::InProgressError
end

Zlib:Inflate is the class for decompressing compressed data. Unlike Zlib::Deflate, an instance of this class is not able to duplicate (clone, dup) itself.

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.

The DidYouMean::Formatter is the basic, default formatter for the gem. The formatter responds to the message_for method and it returns a human readable string.

Raised when the provided IP address is an invalid address.

Raised when the address family is invalid such as an address with an unsupported family, an address with an inconsistent family, or an address who’s family cannot be determined.

Raised when the address is an invalid length.

Default formatter for log messages.
