SSL\TLS Client\Server lib based on Cryptlib Encryption Toolk

Thanks xakep.

I got your code to run, but so far only getting debug messages:

Code: Select all

cl32.dll loaded
cl32 initialized

so I'm sure its something to do with the HTTP code.

The reason I'm commenting is your use of: Procedure ResolveFunc(BaseAddress.l, lpProcName.s)

It appears to be a generic function to search through the Ordinal Table of a DLL to search for the functions you want.
I haven't seen it done this way before. Thanks

We have native function that does exactly that: GetFunction()

@blueb You should use latest cryptlib available: https://www.cs.auckland.ac.nz/~pgut001/cryptlib/
There works fine on win 7 + PB 5.62 x86

@cas Yep, but GetFunction() won't work if you load the library via LoadLibrary( or any other way except of PB's OpenLibrary)

Why is ResolvProc() needed in this case, instead of using GetProcAddress_() ?

[blueb]

Thanks xakep... that solved it.

The TLS code works perfect but what about a server that requires authentication? How do we authenticate?

Also, very interesting for me, google server seems to support TLS v 1.0, 1.1, 1.2, but not 1.3, as cl32_cryptSetAttribute() succeeded with attribute values 1 to 3 but not succeded with 4 for v1.3 or 0 for TLS AUTO.

I tryed the code with TLS_Talk("www.google.com", 443, Headers) and it works well.
Now I would like to do the same to make GET request on a web console management of a switch which use a self signed certificate (on my LAN). This certificate is already register in my certifcate windows store.
When I try the same code (replacing by the ip address of my switch), I've got an error with cl32_cryptSetAttribute(SessionId, #CRYPT_SESSINFO_ACTIVE, 1).
I suppose I should use some Certifcate function but I can't find which one.

Any idea ?
