when I use AES_ofb128_encrypt for decrpyting 2 bytes of data.
Actually I have 18 bytes of data so 16 bytes I am decryting with CBC
and 2 bytes with OFB mode.
For this 2 bytes I am using IV as 16 bytes of decrypted data(means
plaintext),but this 2 bytes data is not maching.
what will be the key her
0 for encryption or decryption?

Ok,
can you expain me how ec_compute_key work and specially this last argument.
Why its need hash value to calculate the secret key.
I need to generate the 56 BYtes shred key.

U mean to say I can generate 64 bytes and then I can ignore last 8
bytes? so I will get 56 bytes.
This value then I have to use as secret key for ECDH

Actaully here I need to write the hash function which generate the 448
bit hash value.
By looking into openssl I did not find any hash function which can
generate the 448 bit.
Do we have any library function for generating 448 bit hash value?

Can anybody guide me how can I generate the digital signature of 56
bytes for ecdsa.
I am using the curve NID_secp224r1.

So is there any relation between curve parameters and public and private keys.

But why we need to load the public key for signing the data?
for signing I need only private key.
When I load the public and private both key I could sign the data.
but when I load only private key and calling Key_check function its failing.

I am getting below error when i enable the error tag
EC_KEY_check_key failed:

Can I load only private part of the key for signing the data?

Hi ,
I run the below two command and generated the private key for ecdsa sign .
But i thinks its not the correct lenght that why my signature creation
is failing.
1.openssl ecparam -out ec_key.pem -name secp224r1 -genkey
2. openssl req -newkey ec:ec_key.pem -x509 -nodes -days 365 -keyout

1.yes it requires perl software

Interested thing is then I configure with all the size is 3.5MB and
when i configure with only above 5.
In that case also same size,it should not compile code for other ciphers right?
