Hi,

I'm new of this group...

My name's Thomas.

I need an algorithm to encrypt a string with the DES encryption, that
works whit the basic auth in PHP.
I've tried some algorithms but the output don't works whit php....

May someone help me??

Thanks a lot everybody....

Bye

Hmm.

There's really only one algorithm for DES. It has several modes of
operation. Maybe you could find out which mode PHP uses?

Thomas, please provide an SSCCE of the sort of thing you've tried.

This is the code i've founded on internet, i don't know if the output
is right or wrong, i only know that php basic auth don't works with
this encryption....

BASIC Authentication does not use DES.

It uses a simple Bse64 encoding of usernameassword !

To clarify. Base authentication is not secure against eavesdropping or
packet sniffing.

So, why here http://it2.php.net/crypt tell me that function crypt()
uses a standard DES encryption...

I need an algorithm to produce an encryption like this

lrB4D/h6wbVTM

to have this output i called this function

crypt("ciao","lr");

Thank you all.

crypt uses DES, but crypt has nothing to do with Basic Authentication.

If you need the crypt functionality in Java then look at:

http://www.dynamic.net.au/christos/crypt/

crypt do use DES, but are not a simple DES.

http://en.wikipedia.org/wiki/Crypt_%28Unix%29

says:

#The traditional implementation uses a modified form of the DES
#algorithm. The user's password is truncated to eight characters, and
#those are coerced down to only 7-bits each; this forms the 56-bit DES
#key. That key is then used to encrypt an all-bits-zero block, and then
#the ciphertext is encrypted again with the same key, and so on for a
#total of 25 DES encryptions. A 12-bit salt is used to perturb the
#encryption algorithm, so standard DES implementations can't be used to
#implement crypt(). The salt and the final ciphertext are encoded into a
#printable string in a form of base 64.

Oh.... and what kind of encryption does the basic auth uses??
