I've tried both to load public key from PEM file, but

got that opnion:

You might try PEM_read_RSA_PUBKEY() instead

It would help if you said what error you get or posted the file.

Perhaps the problem is that you're reading the public key and
trying to sign. Signing uses a private key.
Try:
PEM_read_RSAPrivateKey()
RSA_sign()

Excuse me,
I'm trying, using C, to do a simple sign and verify with RSA public and
private
No no i do it correct.
PEM_read_RSAPrivateKey()
RSA_sign()
For sign and:
PEM_read_RSAPublicKey()
RSA_verify()
For verify

hi again,
i created a publickey.pem with command:
openssl rsa -in myprivate.pem -pubout -out publickey.pem
then in C i try to read this public key with:
RSA *pubkey = PEM_read_RSAPublicKey(fp, NULL, NULL, NULL

i created a publickey.pem with command:
openssl rsa -in myprivate.pem -pubout -out publickey.pem
then in C i try to read this public key with:
RSA *pubkey = PEM_read_RSAPublicKey(fp, NULL, NULL, NULL)
where fp is the opened publickey.pem file.
but it's return this error: error

Hi shankar,
Thanks you for your answer !
You said we can not get public key from a private key .
Then you said So PEM_read_RSAPublicKey() or PEM_read_RSA_PUBKEY() can be used
to load public key from a private key
I'm being confused. Did you mean we those 2 functions can not be use to load

I used PEM_write_RSAPrivateKey() to write private key to a pem file.

The ERR_error_string() only return message like :

Thanks !
I forgot the FAQ, sorry !

Hello,
One thing I will conform you is we can not get public key from a
private key . I do
not remember where i studied , but it is true.
So do not try to get a public key from private key.
This is not true.
Best regards,

Thank you for fast response !
But it's ok if I use PEM_read_RSAPublicKey() to load public key from file save
by using PEM_write_RSAPublicKey().
And even publickey extract by openssl command doesn't have any line as BEGIN
RSA CERTIFICATE. It just has line as BEGIN RSA PUBLIC KEY.
I've tried
PEM_read_RSAPublicKey() or PEM_read_RSA_PUBKEY() can be used to load

The main concept (and also the general concept )in my program ( or any other
programs )is we have to load public key from the certificate only .
In the certificte if the public key does not have
