The dynamic library modifications and Pascal code are copyright 2019-2022 Tobias Giesen. You can find more about PuTTY on the PuTTY Homepage. The TGPuttyLib license is the same as the PuTTY license, so it can be used in both open source and commercial projects.Contributions, requests and other types of feedback are welcome, please send to my name gmail.I fully intend to leave assertions and exceptions enabled in all release versions. I compiled the C code with assertions enabled, but they are implemented as Delphi exceptions via a #define and a callback function.Proxy support has been available since build 8.There is currently no Pascal example for that, so you need to take a look at the sftp_put_file function in psftp.c. That way, you have random access to the file, but the xfer_* functions need to be used in a specific way. You can also open a file directly and obtain a file handle, and implement your own upload loop using the xfer_* functions. You can transfer files from file names or streams.Various demos are included, in particular a fully working SFTP client with GUI (Delphi only), plus a few command line tools written in C++, Delphi and Free Pascal.SSH shell and SCP features will probably be added in a future version.Callbacks (events) will be called in the same thread in which a TTGPuttySFTP method was called – not in the main thread. The class uses 8-bit strings, whereas the component is Unicode (assuming UTF-8 encoding is expected by the SFTP server).
If you choose the class, it must be created completely in source code. You can choose between the TTGPuttySFTP class and the TTGPuttySFTPClient component.Source code changes have been carefully done in a minimalistic fashion so as to ensure easy adoption of changes in future PuTTY releases.Each connection, and each thread, must have its own TTGPuttySFTP instance. The PuTTY DLL is 100% thread-safe and can handle a great number of simultaneous connections and transfers.See our recommendation on GitHub for details. In Delphi, please consider just using the TTGPuttySFTP class in tgputtysftp.pas rather than the TTGPuttySFTPClient component in tgputtysftpclient.pas.View this project on GitHub: /superflexible/TGPuttyLibĭownload TGPuttyLib for Windows and Linux, with source and demos (Build 19, 32 and 64 bit)Ħ4 bit Demo SFTP Client 32 bit Demo SFTP Client The library is currently available for Windows, macOS, Linux and FreeBSD. Ready-to-use classes are currently available for C++, Delphi and Free Pascal. TGPuttyLib is based on PuTTY Release 0.76. Some buffer sizes have been increased to achieve this. It allows developers to transfer files with the highest possible transfer rates. The TGPuttyLib SFTP Library is a library conversion of the psftp program from the well-known PuTTY suite by Simon Tatham.
