For who cares about it, its called "freeBSD md5 crypt" or "unix md5 crypt".
some text i had lying around
MD5 crypt was written by Poul-Henning Kamp for FreeBSD. The main reason
for using MD5 was to avoid problems with American export prohibitions on
cryptographic products, and to allow for a

Free pascal has a unit that does exactly what your posted perlscript
code does

Doesn't this just encrypt the MD5 value of the password?
Just a wild guess..

A MD5 checksum/hash value is an array of 16 bytes, mostly
represented as a hex string, that's what StrMD5() returns.
The MD5 of "test" as a hex string looks like

A ethernet 802.x packet is a struct of:
preamble (8 byte) | destination (6 byte) | source (6 byte) | length (2 byte)
| data (46-1500 byte) | fcs (4 byte)
If fcs (frame

Packets are resent. The amount of packets is depending the size of the
receive window. If memory serve the receive window (where TCP send ACK)
can be till 8 kb.

Why send MD5 checksum ?
To detect errors ?

I assume you use TCP. No need for additional check. I never have seen a
corrupt packet in TCP. Even not on radio networks where there is planty
of noise.

Hello Arno,
AFAIK TCP already does CRC per packet so MD5 may be a bit expensive

Just have a look at IcsMD5.pas unit.
btw: There are also SHA1 hashing, MD4 hashing and DES encryption in ICS.
