Hi,
Thank you very much for the response.
In one protocol, the signature algorithm is defined to be always SHA1. The
encoding to be used
is EMSA-PKCS1-v1_5 encoding as defined in PKCS#1 v2.0 document.
In my implementation, Iam using RSA_private_encrypt instead of RSA_sign()
for signing purpos

is not used in RSA_sign(). If my
understanding is correct, can anyone please point out how to make
RSA_sign() do this job.

RSA_private_encrypt adds only the 0x00 || 0x01 || PS || 0x00 padding
(if padding == RSA_PKCS1_PADDING). If you want to let openssl do the
whole encoding/padding use RSA_sign or if you want to create the T
value manually you need to use i2d_X509_SIG, see RSA_sign.
Correct

My requirement is that I want to sign some data using a specific Hash
Algorithm (SHA1).
For this Iam trying to do the following steps instead of calling
rsa_sign() function directly.
