If you need to compute MD5 digest strings for files or messages in your |
| 2 |
|
|
projects, this stuff might be useful. Remember, though, that I can give |
| 3 |
|
|
you NO WARRANTIES at all (this package is provided "as is"). |
| 4 |
|
|
|

|
|
Files in this package: |
| 6 |
|
|
|
| 7 |
|
|
aamd532.dll - DLL implementing RSA MD5 digest algorithm |
| 8 |
|
|
MD5.bas - A VB MODULE wrapper for the RSA MD5 DLL |
| 9 |
|
|
Wrapper Functions: |
| 10 |
|
|
MD5String (some string) -> MD5 digest of the given string as 32 bytes string |
| 11 |
|
|
MD5File (some filename) -> MD5 digest of the file's content as a 32 bytes string |
| 12 |
|
|
returns a null terminated "FILE NOT FOUND" if unable to open the |
| 13 |
|
|
given filename for input |
| 14 |
|
|
read-me.txt - this file |
| 15 |
|
|
Rivest-MD5.txt - original text and C source code from RSA |
| 16 |
|
|
|
| 17 |
|
|
To install and use: |
| 18 |
|
|
|
| 19 |
|
|
1. Unpack the files. |
| 20 |
|
|
2. Copy the DLL of your choice to somewhere in your search path, so |
| 21 |
|
|
that your applications can find it. |
| 22 |
|
|
IMPORTANT: The aamd532.dll DLL MUST be somewhere in your search path |
| 23 |
|
|
for this to work |
| 24 |
|
|
3. Insert the BAS module in your VB projects. |
| 25 |
|
|
4. Call the wrapper functions as needed. |
| 26 |
|
|
|
| 27 |
|
|
If you don't like VB, or if you need something more elaborate, maybe you should |
| 28 |
|
|
download md5server.zip, at ftp://nt00.esquadro.com.br/md5server.zip. It's |
| 29 |
|
|
an ActiveX instantiable object wrapper around the DLL that can be used from |
| 30 |
|
|
any program, no matter what language you wrote their source code in. This |
| 31 |
|
|
in process server is also free, and can be part of a DELPHI application, |
| 32 |
|
|
for instance. MD5Server.zip is a 1.2 MB bundle. |

RSA required notices follow. |
| 35 |
|
|
|
| 36 |
|
|
The MD5 algorithm is defined in RFC1321. |
| 37 |
|
|
|
| 38 |
|
|
The basic C code implementing the algorithm is derived |
| 39 |
|
|
from that in the RFC and is covered by the following |
