Class MD5

Summary


 An MD5 message digest implementation.  Example use :
 @example
 @ m := MD5()
 @ m.update("here is some input")
 @ m.update("here is some more")
 @ s := m.final()

 This will leave s containing a 16 char string, being the
 digest.

Details
Constructor

MD5(a, b, c, d, bit_count, buffer)

Methods:

F(x, y, z)

FF(a, b, c, d, x, s, ac)

G(x, y, z)

GG(a, b, c, d, x, s, ac)

H(x, y, z)

HH(a, b, c, d, x, s, ac)

I(x, y, z)

II(a, b, c, d, x, s, ac)

decode(block) 


 Transform 64 char string into 16 x 32 bit words
 @p

encode(n) 


 Transform a 32 bit number to 4 corresponding bytes
 @p

final() 


 Complete and return the computation of the digest as
 a string of 16 characters.

final_str() 


 Call final and then convert the result to a 32 bit string
 of lower case hex digits.

reset() 


 Reset this object, so it may be used for another
 computation.  Called by {final()}.

rotate_left(x, n)

transform(block)

update(input) 


 Add some input data to the computation
 @param input a string

Fields:
a
b
bit_count
buffer
c
d
