This module stands as a base class for digest implementation classes.
# File tmp/rubies/ruby-2.4.10/ext/digest/lib/digest.rb, line 41
def self.base64digest(str, *args)
[digest(str, *args)].pack('m0')
end
Returns the base64 encoded hash value of a given string. The return value is properly padded with ‘=’ and contains no line feeds.
static VALUE
rb_digest_class_s_bubblebabble(int argc, VALUE *argv, VALUE klass)
{
return bubblebabble_str_new(rb_funcallv(klass, id_digest, argc, argv));
}
Returns the BubbleBabble encoded hash value of a given string.
static VALUE
rb_digest_class_s_digest(int argc, VALUE *argv, VALUE klass)
{
VALUE str;
volatile VALUE obj;
if (argc < 1) {
rb_raise(rb_eArgError, "no data given");
}
str = *argv++;
argc--;
StringValue(str);
obj = rb_obj_alloc(klass);
rb_obj_call_init(obj, argc, argv);
return rb_funcall(obj, id_digest, 1, str);
}
Returns the hash value of a given string. This is equivalent to Digest::Class.new(*parameters).digest(string), where extra parameters, if any, are passed through to the constructor and the string is passed to digest().
# File tmp/rubies/ruby-2.4.10/ext/digest/lib/digest.rb, line 34
def self.file(name, *args)
new(*args).file(name)
end
Creates a digest object and reads a given file, name. Optional arguments are passed to the constructor of the digest class.
p Digest::SHA256.file("X11R6.8.2-src.tar.bz2").hexdigest # => "f02e3c85572dc9ad7cb77c2a638e3be24cc1b5bea9fdbb0b0299c9668475c534"
static VALUE
rb_digest_class_s_hexdigest(int argc, VALUE *argv, VALUE klass)
{
return hexencode_str_new(rb_funcallv(klass, id_digest, argc, argv));
}
Returns the hex-encoded hash value of a given string. This is almost equivalent to Digest.hexencode(Digest::Class.new(*parameters).digest(string)).
