RSA key generation and writing int to text file.

[krishnamurthy santhanam]

Hi ,

RSA *rsa;
rsa=RSA_generate_key(2048,RSA_F4,NULL,NULL);


I need to write public and private key into text file ...is it possible
using BN?

any suggestion and examples would be great helpful for me.

thanks,
kris

Yes, but for supported formats you don't need to;
see reply to your next message.

If you need to write some other format, it's possible
but more complicated. As an example, 2009-06-20 for
someone needing openssh key format, Mounir Idrassi posted

I have already posted to this list a C code of a program that converts
from an OpenSSL public key to an OpenSSH public key.
http://www.idrix.fr/Root/Samples/pubkey2ssh.c

openssh-public is a mostly-base64 text format.
(openssh-private is the openssl PEM format exactly.)
