This looks wrong. "buf" is not NUL terminated so strtol could give an

Hi,
I'm looking for a way to extract a RSA public key form an x509 certifcat.
Ps: I'm programming with C.
Tks

Hello,
Instead of reading the public key from a file (PEM), I would like to be able to keep the key string in a local char[] variable and be able to generate the RSA*rsa object from it. Can anyone tell me what BIO_xxx steps would be needed to achieve that? Any suggestions would be appreciated. I
Hi,
Yes Layala, you can use the following command line :
openssl genrsa -out your_file 1024
where 1024 reprents the number of bits of your key.

Hi all,
I would like to use RSA public key cryptography. My question is: Is it possible to generate RSA keys from command line and have them stored in a file in order for a C application to access/use them? If not, then what is it the best way to go about this?
Thanks in advance.

Hello:
I found that the resultin file from PEM_write_RSAPublicKey()
function is diferent to the output of openssl x509 -in cert.pem -noout
-pubkey (generated with the same key pair). Is there any way to
extract the public key from a certificate in the same format as what

thanks!
RSA encrypted data should be just read in verbatim into a buffer.

If you have the cert buffer in ASN1 DER encoding, why don't you just use
