Question:

Chilkat Ftp2 (Supports TLS1.2?)

Nov 25 '13 at 09:19

Hello guys,

I'm thinking to write some client in Ruby and been searching for an ftp library, now that i seen chilkat, i'm wondering if TLS1.2 ECDHE/ECDSA ciphers from latest OpenSSL are supported? Cause i using at the moment the trial version and with TLS active on the ftp it gives an issue of:

initialResponse: 220 Welcome
converting to secure connection...
ssl_protocol_3: default
ConvertToTls_4:
  establishChannel2_1:
    clientHelloMajorMinorVersion: 3.1
    buildClientHello:
      majorVersion: 3
      minorVersion: 1
      numRandomBytes: 32
      sessionIdSize: 0
      numCipherSuites: 10
      numCompressionMethods: 1
    --buildClientHello
    TlsAlert:
      level: fatal
      descrip: handshake failure
    --TlsAlert
    Closing connection in response to fatal error.
    Failed to read incoming handshake messages. (1)
    Client handshake failed. (1)
    connectionClosed: 0
  --establishChannel2_1
--ConvertToTls_4
Failed to convert channel to SSL/TLS
Failed to connect to FTP server.
Failed.

--Connect_Ftp2 while: ftp.put_AuthTls(true) is being used.

On FlashFXP it works and gives: TLSv1 negotiation successful... TLSv1 encrypted session using cipher ECDHE-ECDSA-AES256-SHA (256 bits)

I'm sorry to say that it's not yet supported (in v9.4.1). Perhaps in a future version..
