Well the final E in ECHDE stands for ephemeral. It is not really a
difference in the way the algorithm itself works, but more about how
it is used. With ECDH both pa
If this is only ECDH than how to perform ECDHE?

Thanks to you...it's working.
Now i have one last query for you.
I'm generating public and private key files using command line openssl. I
generated 2 .PEM files each for public and private key.
Now i want to generate shared secret from that files using APIs like
EVP_PKEY_derive and others. So,Can

I tried your sample code but compiler showing error like "Undefined refrence
to EVP_PKEY_CTX_new" although i included header file "openssl/evp.h".
You have any idea why this errors occuring???
And by the way thanks for the help friend.

Thanks for giving time to me. I was given a task that i have to implement
ECDHE algorithm means i can use openssl.
So, can you please tell me what i have to do after generatic public and
private key files. How to generate shared secret and what next after that.
Thanks again

Ø I guess I need to know what to research to make all of these guys sort of
use the same cert. is this what chaining could do for me?
Not sure why you need or want a single cert, but if you do then one cert with
multiple subjectAltName extensions should do it.

Unnecessary. EVP_bf_cbc (or EVP_*_cbc) already does PKCS5 padding.

Hi I used the real key and IV now ,
But there is some problem in decrypting firat 16 bytescan you tell why
is this happening...
the first 16 bytes are read properly but not gettin g decrypted??What could
be reason for this?
because of this my code is returning an error in decrypt final..
Than
Hi NaGaGo,
the keylen and ivlen are off by one:
int keyLength = sizeof(uKey) -1; /* == strlen(uKey) */
int ivLength = sizeof(iv) -1;
(and really use it later instead of "8*sizeof(uKey)")

Hi christian,
Thank you very much for your help...I was thinking the same but I already
tried with real key...
and even I changed the code for getting the file size also but yet my

The problem actually is the files which i'm getting when I decrypt the bin
Hi,
you used the ASCII representation of the key, instead of the real key.
Same with iv.

Thanks !
Currently, I've know abit about RSA API from man pages and having another

Hi Trung,
all about cryptography of openssl are in openssl/crypto/... directory (rsa:
openssl/crypto/rsa)
I think if you want to use openssl library you should find documents or
books to read. This library is not simple. One book i would be recommended
with you is "Network security with openssl".
You can try to look for books about SSL/PKI, etc.

You can useWINZIP 5.x to decompress the files.TAR.GZ.
To install, you should read the file INSTALL.W32.
Good luck.
