side it is easy to base64 decode it. As such it gives you the guarantee
it is decoded correctly.
On the other side you should of course also have the reverse chain, but
I don't have an example at hand for that.

I want to encrypt and decrypt using PKCS7_encrypt() and PKCS7_decrypt().
I use this procedure to encrypt so that I can retreive the encrypted buffer
into a char* (and not into a file). Here is the code

Bonjour,
Which part of the examples did you mimic?
32 bytes is the length of a SHA256

Yes, it's correct.
Now I try to feed the ECDSA_do_sign with the output buffer of SHA256. Based on
my security knowledge, I thought that the signing algorithms perform hashing
internally, while in this case it is not true.
Thanks
Hi,
Based on the previous conversations, I tried to generate Elliptic Curve
public/Private key pair. I want to convert the output BIGNUM* to char* in order
to perform the rest of my task. Using BN_bn2hex is the correct api to do this?
It seems it returns a 32 byte Hex while when I generate EC

Hello,
I want to encrypt a small data using recipient public key and decrypt it on
the receiver side using recipient private key. I chose PKCS7_encrypt and
PKCS7_decrypt api to do so. Are they the correct functions? Is there any
other alternative?
Now my problem is that I want to convert the
