If I didn't misunderstand, It will try to negotiate strongest possible 
cipher suite. e.g. If I dont use  SSL_CTX_set_cipher_list() in both the 
server and the client it choses  AES-256. But It depends on your build 
configuration. e.g. If you choose to turn off AES then I think it will 
choose some other cipher suite. But as Richard said you can make cipher 
of your choice defualt cipher by using SSL_CTX_set_cipher_list().

Why won't you use SSL_CTX_set_cipher_list()? Using it you get any 
default you like and don't have to depend on a more or less arbitrary 
OpenSSL default.

thanx richard  for the replay 

I saw all the cipher names but i want to know the default cipher suit supported by 
openssl lib.
if i  write a program using openssl , with out using SSL_CTX_set_cipher_list() 
function what will bw the default cipher set ?
(that is i am not choosing a cipher suit from the list )

once more thanx for the response

Whatever is output with "openssl ciphers"

You get more (almost all) ciphers when you use the command
"openssl ciphers ALL".
