Please ignore this. I already have got the reply from Kris. This mail has been delayed in delivery.

Thanks, Simon. 
It's motivating me further towards using the GnuTLS. 

I have one more question. Is there any possibility to hook my file operation functions (fopen, fread...) with the GnuTLS. 
Basically, I want GnuTLS to call my functions for the file operations.

I saw such callbacks for the socket and memory operations.

Hi, and welcome!

As far as I know, those are the same cipher, RFC 4346 says:

    CipherSuite TLS_RSA_WITH_RC4_128_MD5               = { 0x00,0x04 };

and on http://support.microsoft.com/kb/245030 I see that

SSL_RSA_WITH_RC4_128_MD5	{ 0x00,0x04 }

Anyway, yes, GnuTLS supports that cipher suite.

You may want to look into this comparison between some implementations:


It may not be complete (additions are most welcome), but should give you
some indication on what is supported.

Note that GnuTLS does not support SSL version 2.0 since it has been
broken security-wise.
