SSL handshake failures when no data was sent over Twisted TLSConnection

耗尽温柔 提交于 2019-12-31 05:35:12
问题 I start looking at implementing explicit FTP by extending the current Twisted FTP. Most of the code was straight forward and implementing AUTH, PBSZ, PROT was easy and I got a working secured control channel. My problem is with the data channel. The client side error is : SSL routines', 'SSL3_READ_BYTES', 'ssl handshake failure' It looks like SSL handshake and shutdown are called only when some data was send over the data channel.

How to use a Client Certificate with ftp_ssl_connect

戏子无情 提交于 2019-12-23 01:07:38
问题 I'm looking for the best method to work with an FTP server over an SSL connection. (Generally, pushing a file up as well as getting a list of files on the server). One requirement for this project is that I must use a client side X.509 certificate as part of the authentication process. Can I use a client certificate using the php function ftp_ssl_connect. If so, how? The only other option I've been able to identify would be using curl to work via FTPS. Any suggestions or thoughts would be
