Re: [Synalist] RE : RE : SFTP - error 10091
2012/2/22 Ludo Brands ludo.bra...@free.fr: With Cryptlib I get this same error 10091 (but instead of Network subsystem is unusable I see some squares (some charset problem). I debug into and problem is in function: TSSLCryptLib.Connect In line: if not SSLCheck(cryptSetAttribute(FCryptSession, CRYPT_SESSINFO_ACTIVE, 1)) then Exit; SSLCheck return False, because cryptSetAttribute return -22 (and in SSLCheck is error check if Value0 then error). I can't debug further because cryptSetAttribute is external function Are you getting more information in SSL.LastErrorDesc? You can trace into SSLCheck and verify the value at the end. Ok, so I'm back to stable synapse 39 and cryptlib 3.2.2. So in summary, problem is in function: TSSLCryptLib.Connect In line: if not SSLCheck(cryptSetAttribute(FCryptSession, CRYPT_SESSINFO_ACTIVE, 1)) then Exit; Function cryptSetAttribute return value -22 and send it to SSLCheck. This occur error: FLastErrorDesc := GetString(FCryptSession, CRYPT_ATTRIBUTE_INT_ERRORMESSAGE); Above string is '敓癲牥爠灥牯整㩤䤠癮污摩瀠獡睳牯d'#0#0#0#0#0#0#0#0#0#0#0#0#0#0#0#0.

The chinese characters could mean 2 things. Delphi 10 interpreting the ascii string as unicode or a mismatch with the cryptlib binding and the cryptlib dll loaded. A while ago I was chasing weird bugs in cryptlib which finally turned out to be a wrong cryptlib ddl being picked up. I contributed then a patch to synapse that checks for the correct dll version at run time. I would suggest you try with synapse snapshot or svn and cryptlib 3.2.2.

I have tried this combination too, but this same error Just tried sftp demo with D2006, cl332 and synapse svn. It connects correctly but then raises an out of memory exception in Receive packet in TSimpleSFTP.Init which is well after the SSH authentication. I get also the 10091 error when I mistype the username or password but it gives a nice Server reported: Invalid password after 5-10 seconds. I don't have D2010 so perhaps somebody else can help.

Probably a difference in server. At the beginning of TSimpleSFTP.Init it says //negotiate protocol version (we support version 3 only!) . Although, when I connect with the sftp command line (mingw), and type 'version' at the sftp prompt after logging in, it says SFTP protocol version 3. So there is apparently something wrong in the TSimpleSFTP implementation.

Re: [Synalist] Memory leak in ssl_openssl_lib.TSSLOpenSSL.LoadPFX method
Hi
how exactly was this function imported? what kind of changes was
done?

Hi Lukas,
it seems there is another memory leak
in the method LoadPFX:
...
...
cert := nil;
pkey := nil;
ca := nil;
try {pf}
if PKCS12parse(p12, FKeyPassword, pkey, cert, ca) 0 then
if SSLCTXusecertificate(Fctx, cert) 0 then
if SSLCTXusePrivateKey(Fctx, pkey) 0 then
Result := True;
{pf}
finally
EvpPkeyFree(pkey);
X509free(cert);
SkX509PopFree(ca,_X509Free); // for ca=nil a new STACK is
allocated
end;
{/pf}
...
...
To fix it, I had imported SK_X509_POP_FREE function
and had exported the variable _X509Free to pass it
as a procedural argument.
