[Haskell-cafe] Need urgent help with Network.tls
Hi,
I am trying to use Haskell to download email/attachments from gmail. For
which I am exploring Network.TLS. I got this sample from the net that
connects to gmail smtp and works just fine -
http://hpaste.org/82890
However, when I modify it a bit to try to connect to imap, it simply does
not work. To debug, I tried to connect to a webserver, even that seems to
not work. I modified the function as follows.
emailGmail2 = do
let host = localhost
let port = 443
let params = defaultParamsClient{pCiphers = ciphers}
g - RNG.makeSystem
h - connectTo host (PortNumber (fromIntegral port))
hSetBuffering h LineBuffering
cWrite h GET / HTTP/1.0
cWrite h
cWaitFor h ABCD
con - contextNewOnHandle h params g
handshake con
bye con
And I get a BAD request response from the server - Can some please give
me a sample code that uses Network.TLS to connect to a imap.google.com (or
even a webserver for that matter)?
Regards,
Kashyap

Re: [Haskell-cafe] Need urgent help with Network.tls
You can use HaskellNet http://hackage.haskell.org/package/HaskellNet or
imapget http://hackage.haskell.org/package/imapget directly or look into
their source code for connecting to imap manually.

Re: [Haskell-cafe] Need urgent help with Network.tls
The reason I want to use TLS is that I'd want to pack the whole thing in a
DLL and give it off to a friend for use.
What I am really looking for is a small sample code that demonstrates how
TLS package can be used to connect to a webserver or imapserver.

Kashyap

IMAP is somewhat harder than SMTP; I suggest you read up on the protocol. I've done a fair amount of work with it, and still would have to refer to the RFC to establish a connection without the help of an existing IMAP library. -- brandon s allbery kf8nh sine nomine associates allber...@gmail.com ballb...@sinenomine.net unix, openafs, kerberos, infrastructure, xmonadhttp://sinenomine.net ___ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe

SSL and TLS can be negociated at socket connect. TLS is just the standard name of SSL. at the wire level, TLS1.x is SSL 3.(1+x). What you're refering to is the STARTTLS style protocol command which work independently of the version of TLS (include SSL2, SSL3). Many programs have abused SSL and TLS different name to differentiate how TLS is negociated (straight away, or with a protocol command). Fortunately more and more programs do the right thing and differentiate the two types with the following two options: SSL/TLS or STARTTLS. -- Vincent ___ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe

Re: [Haskell-cafe] Need urgent help with Network.tls
What I am looking to achieve is - create a DLL that would do the complete gmail thing that could be linked to a standard C program (on windows) and could be used to download emails from gmail. What I gathered from HsOpenSSL (which is required for HaskellNet) depends on some native ssl dll That is the reason I wanted to get a standalone library ... again, I might have got the whole thing wrong.
