I am trying to write a program in C which will generate private and public keys using openssl RSA and use these for encryption and decryption. I am able to generate the keys successfully and write these to files. I am able to read the private key successfully. I can encrypt and decrypt using this private key. But finally I want to be able to send the key to another program. So I need to read the public key. But it is returning NULL. This is what I am trying to do.
I have tried replacing the part in read with server_private.key but it is not working.
This is what I get:
success
Public key written succesfully
Private key written succesfully
Enter PEM pass phrase:
Reading of private key successful
rsa_rpu is: 0Reading of public key failed
Encryption success
Decryption success
Plain textTrialString
The encryption and decryption are working because I am populating rsa using the private key for both encryption and decryption
