Re: how to enable ony AES,DES/3DES, RSA algorithm by using MACRO

2008-11-20 Thread Ajeet kumar.S 
Dear All,

Thank you Ger Hobbelt for your help. Actually I tried using your suggestion.
I have doubt it is necessary to use HASH Algorithm(SHA and MD5) for SSL
connection. We can not use only DES, 3DES and AES, RSA Algorithms.

Please clarify doubt.

Thanks allot. 

Thank you.

MD5 is also used for the certificate hash links and the traditional private
key encryption key derivation algorithm. It is possible to avoid the latter
though by using PKCS#8 format.

2008-11-19 Thread Ger Hobbelt 
You can turn OFF specific algorithms using macros - which can also be
configured through the Configure script.

macros all come in the form of

OPENSSL_NO_xyz

e.g. OPENSSL_NO_MDC2

and (IIRC) those same items can be configured through 'Configure
-no_mdc2' and so on.

That way, you can turn off allmost all algorithms.
Check the documentation and the Configure help itself for a complete
list of these.


By the way: I notice you do only wish to use public key and symmetric
key crypto algorithms, and don't list any hash algorithm (such as
SHA); I take it this is intentional?
In that case, you can dispense with the SSL code itself as well (
NO_SSL / -no-ssl ).

  I want to enable only DES/3DES, AES and RSA Algorithm.So please tell me any
 preprocessor definition by using which we can enable only DES/3DES, AES and
 RSA algorithm. I don't want to use other algorithm except above three. Is
 any macro kind of thing is there by which we can enable only above mention
 algorithms?



 Thank you.
