PuTTY Secure Copy Client

As the name suggests, PuTTY Secure Copy Client is a tool derived from PuTTY that enables you to transfer files between computers via a highly secure SSH connection.

Similarly to PuTTY, the application can be accessed via CommandLine or PowerShell and once you run it, you are able to view all the available options. For example, you can connect to a specified port from another computer or you can use the traditional methods, namely to connect with a specified username or login with a given password.

It is worth mentioning that the application allows you to specify whether or not you want to employ Peagant, which is a tool that simplifies the use of PuTTy. To be more precise, Peagent has the role of providing an SSH authorization agent where you can safely store all the private keys. You do not have to bother with remembering your credentials or typing them every time you need to connect to another computer.

You can send a file by specifying the local path, server name and the user it is addressed for, whereas receiving entails copying the data from the server. While you can use wildcards to transfer multiple files in either direction, the developer warns that it is very likely that you are going to receive a warning stating that the remote host tried to write to a file called 'terminal.c'.

To go around this, you can consider upgrading the SSH-2 or using the unsafe option. On a side note, the error is due to an issue in the old-style SCP protocol where the server sends a sequence of file names that match a wildcard pattern. Then again, there is nothing preventing it from sending another pattern than the one specified wildcard.

If you are looking for a reliable and highly secure tool to transfer files between computers without worrying that they might get intercepted, then perhaps you can consider giving PuTTY Secure Copy Client a try.
