|
||||
.Sh DESCRIPTION
|
||||
The MDX functions calculate a 128-bit cryptographic checksum (digest)
|
||||
for any number of input bytes.
|
||||
A cryptographic checksum is a one-way
|
||||
hash-function, that is, you cannot find (except by exhaustive search)
|
||||
the input corresponding to a particular output.
|
||||
This net result is a
|
||||
.Dq fingerprint
|
||||
of the input-data, which doesn't disclose the actual input.
|
||||
.Pp
|
||||
MD4 has been broken; it should only be used where necessary for
|
||||
backward compatibility.
|
||||
MD5 has not yet (1999-02-11) been broken, but recent attacks have cast
|
||||
some doubt on its security properties.
|
||||
The attacks on both MD4 and MD5
|
||||
are both in the nature of finding
|
||||
.Dq collisions
|
||||
\- that is, multiple
|
||||
inputs which hash to the same value; it is still unlikely for an attacker
|
||||
to be able to determine the exact original input given a hash value.
|
||||
.Pp
|
||||
The
|
||||
.Fn MDXInit ,
|
||||
.Fn MDXUpdate ,
|
||||
and
|
||||
.Fn MDXFinal
|
||||
functions are the core functions.
|
||||
Allocate an MDX_CTX, initialize it with
|
||||
.Fn MDXInit ,
|
||||
run over the data with
|
||||
.Fn MDXUpdate ,
|
||||
and finally extract the result using
|
||||
.Fn MDXFinal .
|
||||
.Pp
|
||||
The
|
||||
.Fn MDXPad
|
||||
function can be used to apply padding to the message digest as in
|
||||
.Fn MDXFinal ,
|
||||
but the current context can still be used with
|
||||
.Fn MDXUpdate .
|
||||
.Pp
|
||||
The
|
||||
.Fn MDXTransform
|
||||
function is used by
|
||||
.Fn MDXUpdate
|
||||
to hash 512-bit blocks and forms the core of the algorithm.
|
||||
Most programs should use the interface provided by
|
||||
.Fn MDXInit ,
|
||||
.Fn MDXUpdate
|
||||
and
|
||||
.Fn MDXFinal
|
||||
instead of calling
|
||||
.Fn MDXTransform
|
||||
directly.
|
||||
.Pp
|
||||
.Fn MDXEnd
|
||||
is a wrapper for
|
||||
.Fn MDXFinal
|
||||
which converts the return value to an MDX_DIGEST_STRING_LENGTH-character
|
||||
(including the terminating '\e0')
|
||||
.Tn ASCII
|
||||
string which represents the 128 bits in hexadecimal.
|
||||
.Pp
|
||||
.Fn MDXFile
|
||||
calculates the digest of a file, and uses
|
||||
.Fn MDXEnd
|
||||
to return the result.
|
||||
If the file cannot be opened, a null pointer is returned.
|
||||
.Pp
|
||||
.Fn MDXFileChunk
|
||||
behaves like
|
||||
.Fn MDXFile
|
||||
but calculates the digest only for that portion of the file starting at
|
||||
.Fa offset
|
||||
and continuing for
|
||||
.Fa length
|
||||
bytes or until end of file is reached, whichever comes first.
|
||||
A zero
|
||||
.Fa length
|
||||
can be specified to read until end of file.
|
||||
A negative
|
||||
.Fa length
|
||||
or
|
||||
.Fa offset
|
||||
will be ignored.
|
||||
.Fn MDXData
|
||||
calculates the digest of a chunk of data in memory, and uses
|
||||
.Fn MDXEnd
|
||||
to return the result.
|
||||
.Pp
|
||||
When using
|
||||
.Fn MDXEnd ,
|
||||
.Fn MDXFile ,
|
||||
.Fn MDXFileChunk ,
|
||||
or
|
||||
.Fn MDXData ,
|
||||
the
|
||||
.Ar buf
|
||||
argument can be a null pointer, in which case the returned string
|
||||
is allocated with
|
||||
.Xr malloc 3
|
||||
and subsequently must be explicitly deallocated using
|
||||
.Xr free 3
|
||||
after use.
|
||||
If the
|
||||
.Ar buf
|
||||
argument is non-null it must point to at least MDX_DIGEST_STRING_LENGTH
|
||||
characters of buffer space.

.Sh HISTORY
|
||||
These functions appeared in
|
||||
.Ox 2.0 .
|
||||
.Sh AUTHORS
|
||||
The original MDX routines were developed by
|
||||
.Tn RSA
|
||||
Data Security, Inc., and published in the above references.
|
||||
This code is derived from a public domain implementation written by Colin Plumb.
|
||||
.Pp
|
||||
The
|
||||
.Fn MDXEnd ,
|
||||
.Fn MDXFile ,
|
||||
.Fn MDXFileChunk ,
|
||||
and
|
||||
.Fn MDXData
|
||||
helper functions are derived from code written by Poul-Henning Kamp.
|
||||
.Sh BUGS
|
||||
Collisions have been found for the full versions of both MD4 and MD5
|
||||
as well as strong attacks against the SHA-0 and SHA-1 family.
|
||||
The use of
|
||||
.Xr sha2 3 ,
|
||||
or
|
||||
.Xr rmd160 3
|
||||
is recommended instead.

* To compute the message digest of a chunk of bytes, declare an
|

* MD5Context structure, pass it to MD5Init, call MD5Update as
