Re: Hoping for a working example of SFTP in PHP

I was mainly interested in the last two file_get_contents() calls. If there
was some sort of a permission issue the script should have output one or
two error messages. But since that's not the case, then probably your
script can read the keys just fine, and the issue is elsewhere. I can also
tell that the process that executes the php script runs under the user
SYSTEM (which is not that helpful).

Some more info I found (which you've probably read already)

"The prerequisite that you mention, namely the pubkey file not to have any
comments and not even have a trailing newline is incorrect (and the newline
thingy absurd when you think it through).

If your scriptfails, you have prob. sooner stumbled into the ssh2 bug that
makes ssh2 fail when it is compiled wuth libgcrypt instead of openssl. The
workaround is to create a PEM formatted copy of your private key file in
PEM format with openssl:

~/.ssh> openssl rsa -in id_rsa -out id_rsa.pem
Then, in ssh2_auth_pubkey_file() in your PHP script, use id_rsa.pem as
privkey file instead of id_rsa, and omit the passphrase. That should make
it work."

Maybe give that a go as well.
