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
.
key = "key" data = "message-to-be-authenticated" mac = OpenSSL::HMAC.hexdigest("SHA256", key, data) #=> "cddb0db23f469c8bf072b21fd837149bd6ace9ab771cceef14c9e517cc93282e"
data1 = File.binread("file1") data2 = File.binread("file2") key = "key" hmac = OpenSSL::HMAC.new(key, 'SHA256') hmac << data1 hmac << data2 mac = hmac.digest

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.

Parent class for informational (1xx) HTTP
response classes.
An informational response indicates that the request was received and understood.
References:
Response class for Non-Authoritative Information
responses (status code 203).
The Non-Authoritative Information
response indicates that the server is a transforming proxy (such as a Web accelerator) that received a 200 OK response from its origin, and is returning a modified version of the origin’s response.
References:
Response class for Moved Permanently
responses (status code 301).
The Moved Permanently
response indicates that links or records returning this response should be updated to use the given URL.
References:
Response class for Permanent Redirect
responses (status code 308).
This and all future requests should be directed to the given URI
.
References:
Response class for Too Many Requests
responses (status code 429).
The user has sent too many requests in a given amount of time.

Map from option/keyword string to object with completion.
This represents a magic comment that was encountered during parsing.
Base class for all Gem
commands. When creating a new gem command, define initialize, execute
, arguments
, defaults_str
, description
and usage
(as appropriate). See the above mentioned methods for details.
A very good example to look at is Gem::Commands::ContentsCommand
Generated when trying to lookup a gem to indicate that the gem was found, but that it isn’t usable on the current platform.
fetch and install read these and report them to the user to aid in figuring out why a gem couldn’t be installed.
