Module description

md5 -- MD5 Message Digest Algorithm

The md5 module implements the MD5 algorithm.

MD5 Structure

md5% ( -- n )

Get the required space for a md5 variable

MD5 variable creation, initialisation and destruction

md5-init ( md5 -- )

Initialise the MD5 variable

md5-create ( "<spaces>name" -- ; -- md5 )

Create a named MD5 variable in the dictionary

md5-new ( -- md5 )

Create a new MD5 variable on the heap

md5-free ( md5 -- )

Free the MD5 variable from the heap

MD5 words

md5-reset ( md5 -- )

Reset the MD5 state

md5-update ( c-addr u md5 -- )

Update the MD5 with more data c-addr u

md5-finish ( md5 -- u1 u2 u3 u4 )

Finish the MD5 calculation, return the result u1 u2 u3 u4

md5+to-string ( u1 u2 u3 u4 -- c-addr u )

Convert MD5 result to the string, using the pictured output area

Inspection

md5-dump ( md5 -- )

Dump the md5 variable

include ffl/md5.fs

\ Create a MD5 variable md1 in the dictionary

md5-create md1

\ Update the variable with data

s" The quick brown fox jumps over the lazy dog" md1 md5-update

\ Finish the MD5 calculation resulting in four unsigned 32 bit words
\ on the stack representing the hash value

md1 md5-finish

\ Convert the hash value to a hex string and print it

md5+to-string type cr



\ Create a MD5 variable on the heap

md5-new value md2

\ Update the variable with multiple data

s" The quick brown fox "    md2 md5-update
s" jumps over the lazy dog" md2 md5-update

\ Finish the calculation

md2 md5-finish

\ Convert the hash value to a hex string and print

md5+to-string type cr

\ Free the variable from the heap

md2 md5-free
