  1. Hi, I am using TSslWSocket (TSslContext) to connect to TSslWSocketServer (using IcsHosts) Is it possible to avoid TSslContext on Client Side too ? I am asking because the Client side loses out some data initially upon just connecting. Without SSL same code work fine. I tried to prepare a small sample but that works fine with SSL too. I am using Delphi Seattle on Windows 10, Single machine, Two Exe's (Server and Client) for testing Regards Allan
  2. The function declarations for f_EVP_PKEY_get_raw_private_key() and f_EVP_PKEY_get_raw_public_key() each have a wrong parameter type: outlen: Integer. The correct type is outlen: size_t. On 64-bit, this can lead to memory overwrite if the 64-bit size_t is written to the 32-bit Integer. Reference: https://www.openssl.org/docs/man1.1.1/man3/EVP_PKEY_get_raw_private_key.html Ralf
  3. The patch below suggests fixes for 7 memory leaks in OverbyteIcsWSocket.pas. They surfaced after the OverbyteIcsSslWebServ.dpr sample project was linked against YuOpenSSL. A total of > 10k memory allocations reported not freed, adding up to > 500k bytes of leaked memory. The leaks were easy to spot because YuOpenSSL does not use the OpenSSL DLLs but compiles all OpenSSL code into the application binary. As a side effect, YuOpenSSL uses the Delphi memory manager and by default allows memory trackers to see OpenSSL memory allocations. Otherwise this does normally not happen when the OpenSSL DLLs employ their own memory management. The leaks then sum up in the DLLs' memory space, and out of sight of Delphi's memory trackers. For anyone who would like to test their ICS applications for memory leaks with YuOpenSSL, here is the link: https://www.yunqa.de/delphi/products/openssl/index Index: OverbyteIcsWSocket.pas =================================================================== --- OverbyteIcsWSocket.pas (revision 1492) +++ OverbyteIcsWSocket.pas (working copy) @@ -13933,7 +13933,8 @@ for I := 0 to Result - 1 do begin P := f_OPENSSL_sk_value(CertStack, I); if Assigned(P) then { V8.64 sanity test } - Add(f_X509_dup(PX509(P))); + // Add(f_X509_dup(PX509(P))); // ralfjunker fix memory leak. + Add(PX509(P)); // ralfjunker fix memory leak. end; end; @@ -14866,7 +14867,8 @@ OneErr := String(LastOpenSslErrMsg(FALSE)); OneErr := 'Error Cert ' + IntToStr(tot) + ' - ' + OneErr; end; - end; + // end; ralfjunker fix memory leak. + end else f_BIO_free(MemBio); // ralfjunker fix memory leak. // ignore private keys and other stuff if OneErr <> '' then begin @@ -17369,7 +17371,8 @@ procedure TX509Base.FreeAndNilX509Inters; { V8.41 } begin if Assigned(FX509Inters) then begin - f_OPENSSL_sk_free(FX509Inters); + // f_OPENSSL_sk_free(FX509Inters); // ralfjunker fix memory leak. + f_OPENSSL_sk_pop_free(FX509Inters, @f_X509_free); // ralfjunker fix memory leak.

  5. How to send files to an API using TSslHttpRest? In Postman I can, this is the http code: POST /api/br-invoice-integration/v1/batches HTTP/1.1 Host: qed.onvio.com.br Accept: application/json Authorization: Bearer 42dc0b99-2d17-4898-9c85-0b52ae364c63Content-Type: multipart/form-data; boundary=----WebKitFormBoundary7MA4YWxkTrZu0gW ----WebKitFormBoundary7MA4YWxkTrZu0gW Content-Disposition: form-data; name="file[]"; filename="/C:/MyFile.xml" Content-Type: text/xml (data) ----WebKitFormBoundary7MA4YWxkTrZu0gW Content-Disposition: form-data; name="query" {"boxe/File":true} ----WebKitFormBoundary7MA4YWxkTrZu0gW With SslHttpRest, I'm trying to SendStream, like that (similar to the sample OverbyteIcsHttpPost1): FileName := 'C:\MyFile.xml'; RandBoundary := '-----------------------------' + IntToHex(Random(MaxInt), 8) + IntToHex(Random(MaxInt), 8); SslHttpRest1.ContentTypePost := 'multipart/form-data; boundary=' + RandBoundary; Header := RandBoundary + #13#10 + 'Content-Disposition: form-data; name="file[]"; filename="' + 'MyFile.xml' + '"' + #13#10 + 'Content-Type: text/xml' + #13#10 + #13#10; Footer := RandBoundary + #13#10 + 'Content-Disposition: form-data; name="query"' + #13#10 + #13#10 + '{"boxe/File":true}' + #13#10 + RandBoundary + #13#10; SslHttpRest1.SendStream := TMultiPartFileReader.Create(Filename, Header, Footer); SslHttpRest1.SendStream.Position := 0; SslHttpRest1.RestRequest(httpPOST, Myurl); But it doesn't work, just get error: Request completed: 500 Request done, StatusCode #500 {"error":{"code":500,"errors":[],"message":"HTTP 400 Bad Request"}} Has anyone ever needed to do something similar, would this be the way? If anyone can help, I appreciate it.
  6. Hello Community, since last week I have been trying to let a TsslWSocket and a TsslWSocketServer communicate with each other. I want to get a long-term stable connection between a TCP client and a TCP server that is secured with TLS1.3. However, after a runtime of a few minutes, the data transfer breaks down. There is a client thread and a server thread. In the respective Execute method I create the socket and initialize it, call Listen (server) or Connect (client) and run the MessageLoop. After a successful SSL handshake, my client sends 128KB data packets to the server. The data arrives at the server, TwSocketClient.onDataAvailable is triggered, the bytes can be read there with TwSocketClient (Sender).Receive (pBuffer ...). When the server has received 128KB, it sends an "ACK" packet to the client (An AnsiString "ACK", 3 bytes). When the client receives the packet, it sends again 128KB of testdata. This works a few thousand, sometimes some tenthousands times, until TwSocketClient.onDataAvailable is suddenly no longer called. There is no OnSessionClosed, no onError, no onException and also no onBgException that would indicate a problem. Apparently the problem is on the client side: A running Wireshark shows an [ACK] packet from the server to the client as last entry. Further clicks on the "Manual Send" button do not lead to any further lines in the Wireshark log. When this state has been reached another client can connect to the server without any problems, so the server is not completely dead. I have no idea what I could do wrong ... Maybe it's not ok to send in the context of another thread? But how is that supposed to work when the client thread is blocked by the MessageLoop? Simultaneous web browsing leads to the problem faster. When I look at any website, it usually takes less than half a minute to see the problem. My test project is attached. I would be interested to know if you have observed the same problem and if anyone has a guess as to what might be the cause ... The project is complete, the Win32 folder also contains the certificate used for testing ... Usage: Enter your own IP address, press the "btCreateStart" button, then the "btSendData Manual Send" button. The "logICStest.log" file in the program directory grows until the problem occurs ... Thanks in advance... P.S: I have already tried not to send after receiving the ACK packet, but cyclically via timer or thread. If you can select both in the test project with checkboxes, the result is the same. The problem does not only occur with TLS1.3, also with TLS1.2. I even think it shows up without encryption, just takes longer ...

  10. In OverbyteIcsWSocket.pas, PunyServerName is always filled with 8-bit data, even if it is a 16-bit UnicodeString on Unicode Delphis. This happens in OverbyteIcsWSocket.pas line 15916 (SVN 1469): Move(DataExt[5], Ws.FCliHelloData.PunyServerName[1], Slen); The line above works well with non Unicode Delphis, but copies incorrect data in Unicode enabled Delphis. Cause is the declaration of PunyServerName (line 3488): TClientHelloData = record ServerName: String; PunyServerName: String; // <-- Problem here. ... Later on, this results in incorrect conversion to ServerName. See that the OverbyteIcsSslWebServ demo outputs garbled SNI and Server Name instead of localhost: HTTPS Server is waiting for connections https://localhost/demo.html HTTP Server is waiting for connections http://localhost/demo.html [10:17:36] SNI "潬慣桬獯t Client Hello: Server Name: 潬慣桬獯t [10:18:15] SNI "潬慣桬獯t Client Hello: Server Name: 潬慣桬獯t A quick remedy is to declare PunyServerName as AnsiString and work around the warning "OverbyteIcsWSocket.pas(15968): W1057 Implicit string cast from 'AnsiString' to 'string'", possibly be adding a typecast. TClientHelloData = record ServerName: String; PunyServerName: AnsiString; // <-- 8-bit string, even in Unicode Delphis. ... Ralf

  12. Dear All, I need to fill two fields in a form and then submit it. As I'm not well versed in this area, I come here and for some guidance. The page where they sit is coded as follows: <html> <body> <form id="form1" name="form1" action="envia_arq2.php" method="post"> Senha: <input TYPE="password" NAME="senha" SIZE="12"><br /><br /> Seu nome: <input TYPE="text" NAME="nome" SIZE="12"> <input name="enviar" type="submit" value="Enviar"> </form> </body> </html> This is a FMX application, so I can't use TWebBrowser as I've found in several articles in the internet. Furthermore, even the VCL version I couldn't make work, after navigating to the page the Document property is nil, making it impossible to retrieve the fields as indicated in those articles. I then moved on to ICS TSslHttpCli, tried a few basic things, but I came up empty on the very first attempt where I just set the URL (https://www.trivial.com.br/envia_arq2.htm) and did a GET to try and see how to proceed from there. An exception is raised signaling a missing SSL Context. Perhaps this is not the way to go. Could you please kindly share some light on this? Thanks in advance. -- Carlos

  14. OverbyteIcsWSocket.pas has at least one small memory leak. In line 17009 (SVN 1464), an X509Obj is duplicated before its is added to the list. However, TX509Base.Create() duplicates the duplication once more before TX509List.Add() stores it to the list. The first duplicated object is never freed, resulting in the leak. This is the line in question: CertList.Add(f_X509_dup(f_X509_OBJECT_get0_X509 (MyX509Obj))); The fix is to remove f_X509_dup(), so the line looks like this: CertList.Add(f_X509_OBJECT_get0_X509 (MyX509Obj)); Code analysis suggests that a similar leak is present in line 15012, but I have not been able to trigger this code running one of the Sample projects: Cert.AddToInters(f_X509_dup(f_X509_OBJECT_get0_X509 (MyX509Obj))); Ralf

  16. OverbyteIcsSSLEAY.pas line 2160 (SVN 1464) declares f_SSL_set_msg_callback() to use a TProto_msg_cb callback.

The Pascal declaration passes sk and scvsvs as simple pointers, instead of pointer addresses or var parameters. In contrast, the C header uses a double pointer for both parameters: int SSL_bytes_to_cipher_list(SSL *s, const unsigned char *bytes, size_t len, int isv2format, STACK_OF(SSL_CIPHER) **sk, STACK_OF(SSL_CIPHER) **scsvs); Reference: https://www.openssl.org/docs/man1.1.1/man3/SSL_bytes_to_cipher_list.html Ralf
  19. I am using ICS TSslFTPServer (FtpSslType=ftpAuthTls,ftpAuthSsl) and TSslWSocketServer (SslEnable=True) on my Server side application along with TSslContext wherein I am pointing to SslPrivKeyFile and SslCertFile to your sample 01key.pem and 01cert.pem respectively. My Client Application connects and all is well. problem-1) If I try to change the certificates to another of your provided examples or If I build with OpenSSL it gives error 'Can't read certificate file ... error:0909006C:PEM routines:get_name:no start line' problem-2) Using SSL I lose compatibility with WinXP and probably with Vista too. Is there a workaround ? (Angus has suggested me to use the IcsHosts property instead of SslContext but I will need to do more work to get it working for me, hope I am using above mentioned components properly to begin with SSL) (How I generated my own PEM files openssl genpkey -aes256 -algorithm RSA -pkeyopt rsa_keygen_bits:2048 -out 01key.pem openssl pkey -in 01key.pem -out 01cert.pem -pubout)
  20. I am using TSslFtpServer , TSslWSocketServer along with TSSLContext component successfully when using the SslCAFile , SslCertFile and SslPrivateKeyFile properties to point to files on the Hard Disk. I noticed there are matching SslCALines , SslCertLines and SslPrivateKeyLines . I filled these properties with text from the corresponding files but it did not work. I am asking this because I would prefer not to expose the Certificate files.

    Some assistance on SSL required

    Hi, I am using ICS TFTPServer and TWSocketServer on my Server side application (Delphi Seattle). I want to use SSL to secure the connections. This question is more related to SSL rather than ICS. I have read on SSL and checked the Demo programs too. I yet need some clarity. Mine is a backup application and will be sending critical data over the WAN. If I generate my own certificates via OpenSSL where do I keep the PEM files for the ICS Server components to access ? Should I generate a different PEM file per customer upon installation or can I supply a common one ? I files are large can I have only password exchanged secretly and data without encryption (My data is already compressed with AES ) ? Regards Allan (Thanks for all the new features in ICS)

  25. Hi, I use TSslFtpClient component for connecting to a server via SSL (TSL connections), and also TSslContext and TSslAvlSessionCache. I can connect and trasfer some file, but after a while (7/8 seconds, and about 145 files) the session (not the connection) closes, so I close also the connection and restart it. I would know if is it possible avoid expire the session and do a reconnect to the server. I have to transfer also thousands of file at a time Thanks in advance PS: if I try to copy many file with the OverbyteIcsXferTst1 example, that use TIcsFtpMulti, It give me "FTP Session Closed - Connection reset by peer (#10054)" after only having transferred 45 files
