According to the CHANGELOG.md files, SCP was dropped at version 3.0.0 from this product. But the product description continues to state: "phpseclib is a PHP library that provides pure-PHP implementations of: BigIntegers RSA SSH1 SSH2 SFTP SCP ..."
One would think that after almost five years, someone would have documented a reason for this, and (at the very least) instruction for what to do in order to continue using functions that equate to Net_SCP->get() and NET_SCP->put(). But this sort of information seems sorely lacking, even on information-overload internet.
Is there really no SCP(ish) capability remaining in phpselib? Seems like a huge reduction of feature - that is, by far, the most-used PHPSECLIB capability in my own scripts at least. And I would think the need is not unique to me.
