** MD5(Class)
|
|
|
|
A class to implement MD5 Message-Digest Algorithm by RSA Data
|
|
Security, Inc., described in RFC1321.
|
|
|
|
Superclass: Object
|
|
|
|
Class Methods:
|
|
|
|
new([str])
|
|
md5([str])
|
|
|
|
Creates a new MD5 object. If a string argument is given, it
|
|
is added to the object. (see update.)
|
|
|
|
Methods:
|
|
|
|
clone
|
|
|
|
Copies the MD5 object.
|
|
|
|
digest
|
|
|
|
Returns the MD5 hash of the added strings as a string of 16
|
|
bytes.
|
|
|
|
hexdigest
|
|
|
|
Returns the MD5 hash of the added strings as a string of 32
|
|
hexadecimal digits. This method is equal to:
|
|
|
|
def hexdigest
|
|
ret = ''
|
|
digest.each_byte {|i| ret << sprintf('%02x', i) }
|
|
ret
|
|
end
|
|
|
|
update(str)
|
|
<< str
|
|
|
|
Update the MD5 object with the string str. 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.
