Superclass: Digest::Base

|
||||
|
||||
|
||||
Those above classes provide a common interface as shown below.
|
||||
|
||||
|
||||
Class Methods:
|
||||
|
||||
new([str])
|
||||
|
||||
Creates a new digest object. If a string argument is given,
|
||||
it is added to the object. (see update.)
|
||||
|
||||
digest(str)
|
||||
|
||||
Immediately calculates and return the hash of the given
|
||||
strings as a string. Equivalent to new(str).digest.
|
||||
|
||||
hexdigest(str)
|
||||
|
||||
Immediately calculates and return the hash of the given
|
||||
strings as a string of hexadecimal digits. Equivalent to
|
||||
new(str).hexdigest.
|
||||
|
||||
Methods:
|
||||
|
||||
clone
|
||||
|
||||
Creates a copy of the digest object.
|
||||
|
||||
digest
|
||||
|
||||
Returns the hash of the added strings as a string of 16 bytes
|
||||
for MD5, 20 bytes for SHA1 and RMD160, 32 bytes for SHA256, 48
|
||||
bytes for SHA384, and 64 bytes for SHA512.
|
||||
|
||||
hexdigest
|
||||
to_s
|
||||
|
||||
Returns the hash of the added strings as a string of 32
|
||||
hexadecimal digits for MD5, 40 hexadecimal digits for SHA1 and
|
||||
RMD160, 64 hexadecimal digits for SHA256, 96 hexadecimal
|
||||
digits for SHA384, and 128 hexadecimal digits for SHA512.
|
||||
This method is equal to:
|
||||
|
||||
def hexdigest
|
||||
digest.unpack("H*")[0]
|
||||
end
|
||||
|
||||
update(str)
|
||||
<< str
|
||||
|
||||
Appends the string str to the digest object. Repeated calls
|
||||
are equivalent to a single call with the concatenation of all
|
||||
the arguments, i.e. m.update(a); m.update(b) is equivalent to
|
||||
m.update(a + b) and m << a << b is equivalent to m << a + b.
|
||||
|
||||
== md
|
||||
|
||||
Checks if the object is equal to the given digest object.
|
||||
|
||||
== str
|
||||
|
||||
Regards the value as either a digest value or a hexdigest
|
||||
value (depending on the length) and checks if the object is
|
||||
equal to the given string.

これらのクラスは以下のような共通のインターフェースを提供する。
|
||||
|
||||
|
||||
Class Methods:
|
||||
|
||||
new([str])
|
||||
|
||||
新しいダイジェストオブジェクトを生成する．文字列引数が与えられる
|
||||
とそれを追加する(see update)。
|
||||
|
||||
digest(str)
|
||||
|
||||
与えられた文字列に対するハッシュ値を文字列で返す。
|
||||
new(str).digest と等価。
|
||||
|
||||
hexdigest(str)
|
||||
|
||||
与えられた文字列に対するハッシュ値を、ASCIIコードを使って
|
||||
16進数の列を示す文字列にエンコードして返す。
|
||||
new(str).hexdigest と等価。
|
||||
|
||||
Methods:
|
||||
|
||||
clone
|
||||
|
||||
ダイジェストオブジェクトの複製を作る。
|
||||
|
||||
digest
|
||||
|
||||
今までに追加した文字列に対するハッシュ値を文字列で返す。MD5では
|
||||
16バイト長、SHA1およびRMD160では20バイト長、SHA256では32バイト長、
|
||||
SHA384では48バイト長、SHA512では64バイト長となる。
|
||||
|
||||
hexdigest
|
||||

今までに追加した文字列に対するハッシュ値を、ASCIIコードを使って

|
||||
SHA1およびRMD160では40バイト長、SHA256では64バイト長、SHA384では

96バイト長、SHA512では128バイト長となる。Rubyで書くと以下と同じ。

|
||||
end
|
||||
|
||||
update(str)
|
||||
<< str
|
||||
|
||||
文字列を追加する。複数回updateを呼ぶことは文字列を連結して
|
||||
updateを呼ぶことと等しい。すなわち m.update(a); m.update(b) は
|
||||
m.update(a + b) と、 m << a << b は m << a + b とそれぞれ等価
|
||||
である。
|
||||

||||
|
||||
