;Task: Encode a string using an MD5 algorithm. The algorithm can be found on [[wp:Md5#Algorithm|Wikipedia]].
Optionally, validate your implementation by running all of the test values in [http://tools.ietf.org/html/rfc1321 IETF RFC (1321) for MD5].
Additionally, RFC 1321 provides more precise information on the algorithm than the Wikipedia article.
{{alertbox|lightgray|'''Warning:''' MD5 has [http://tools.ietf.org/html/rfc6151 known weaknesses], including '''collisions''' and [http://www.win.tue.nl/hashclash/rogue-ca/ forged signatures]. Users may consider a stronger alternative when doing production-grade cryptography, such as SHA-256 (from the SHA-2 family), or the upcoming SHA-3.}}
If the solution on this page is a library solution, see [[MD5/Implementation]] for an implementation from scratch.

Emacs Lisp
Emacs 23 and up includes md5 giving the MD5 hash as a hexadecimal string. (See [http://www.gnu.org/software/emacs/manual/html_node/elisp/Checksum_002fHash.html GNU Elisp manual on Checksum/Hash]).
(md5 "The quick brown fox jumped over the lazy dog's back") => "e38ca1d920c4b8b8d3946b2c72f01680"
This began in [http://git.chise.org/elisp/flim/ FLIM] and FLIM has an md5.el which creates an md5 func if it doesn't already exist.
hmac-md5.el also from FLIM and also included in recent Emacs has an md5-binary giving the checksum as 16 binary bytes. encode-hex-string from hex-util.el can convert that to hex the same as the md5 func gives.
(require 'hmac-md5) (require 'hex-util) (encode-hex-string (md5-binary "The quick brown fox jumped over the lazy dog's back")) => "e38ca1d920c4b8b8d3946b2c72f01680"
Erlang
By default, Erlang's crypto functions like md5 return a binary value rather than a hex string. We have two write our own function to translate it:
-module(tests). -export([md5/1]). md5(S) -> string:to_upper( lists:flatten([io_lib:format("~2.16.0b",[N]) || <<N>> <= erlang:md5(S)]) ).
Testing it:
c(tests).
{ok,tests}
2> tests:md5("The quick brown fox jumped over the lazy dog's back").

The MD5-DIGEST function is readily available, the output is passed thru HEX-ENCODE to convert the raw result to a hexadecimal string, this then needs to be passed thru STRING for display purposes.

RLaB
RLaB has a built-in function ''hash,'' : which implements hash functions ''fn'' as "md2", "md5", "sha", "sha1", "dss", "dss1" and "ripemd160", for given string vector ''ss'' and new-line delimiter ''nl''. The last is here so that a hash of a string vector calculated in RLaB is the same as the hash of the same string vector written to a file.
x = "The quick brown fox jumped over the lazy dog's back"
The quick brown fox jumped over the lazy dog's back

UNIX Shell
Shells execute system commands (such as ''md5sum'', in this case). We must pass "-n" to ''echo'', so no trailing newline is appended, which would change the MD5-hash.
[[GNU]] coreutils has ''md5sum'':
echo -n "The quick brown fox jumped over the lazy dog's back" | md5sum
Several [[BSD]] systems have ''md5:''
echo -n "The quick brown fox jumped over the lazy dog's back" | md5
