Returns the resulting hash value and resets the digest to the initial state.
If none is given, returns the resulting hash value of the digest in a hex-encoded form, keeping the digest’s state.
If a string is given, returns the hash value for the given string in a hex-encoded form, resetting the digest to the initial state before and after the process.
Returns the resulting hash value in a hex-encoded form and resets the digest to the initial state.
Returns digest_obj.hexdigest().
If none is given, returns the resulting hash value of the digest in a base64 encoded form, keeping the digest’s state.
If a string is given, returns the hash value for the given string in a base64 encoded form, resetting the digest to the initial state before and after the process.
In either case, the return value is properly padded with ‘=’ and contains no line feeds.
Returns the resulting hash value and resets the digest to the initial state.
Creates a class to wrap the C struct described by signature.
MyStruct = struct ['int i', 'char c']
Construct a new class given a C:
class klass (CUnion, CStruct, or other that provide an entity_class)
types (Fiddle::TYPE_INT, Fiddle::TYPE_SIZE_T, etc., see the C types constants)
corresponding members
Fiddle::Importer#struct and Fiddle::Importer#union wrap this functionality in an easy-to-use manner.
Examples:
require 'fiddle/struct' require 'fiddle/cparser' include Fiddle::CParser types, members = parse_struct_signature(['int i','char c']) MyStruct = Fiddle::CStructBuilder.create(Fiddle::CUnion, types, members) MyStruct.malloc(Fiddle::RUBY_FREE) do |obj| ... end obj = MyStruct.malloc(Fiddle::RUBY_FREE) begin ... ensure obj.call_free end obj = MyStruct.malloc begin ... ensure Fiddle.free obj.to_ptr end

Similar to read, but raises EOFError at end of string instead of returning nil, as well as IO#sysread does.

Reads size bytes from the stream. If buf is provided it must reference a string which will receive the data.
See IO#read for full details.
Reads at most maxlen bytes from the stream. If buf is provided it must reference a string which will receive the data.
See IO#readpartial for full details.
Reads a line from the stream which is separated by eol.
Raises EOFError if at end of file.
Reads a one-character string from the stream. Raises an EOFError at end of file.
Reads a DER or PEM encoded string from string or io and returns an instance of the appropriate PKey class.
_string+ is a DER- or PEM-encoded string containing an arbitrary private or public key.
io is an instance of IO containing a DER- or PEM-encoded arbitrary private or public key.
pwd is an optional password in case string or io is an encrypted PEM resource.
Return true if the PRNG has been seeded with enough data, false otherwise.

Generate a Form element as a string.
method should be either “get” or “post”, and defaults to the latter. action defaults to the current CGI script name. enctype defaults to “application/x-www-form-urlencoded”.
Alternatively, the attributes can be specified as a hash.
See also multipart_form() for forms that include file uploads.
