Hello,
I need to extract the RSA public key from a RSA private key using OpenSSL.
I'm currently using |RSAPublicKey_dup()| passing the |RSA*| private key
to get the public key. However, while the call seems to work, I cannot
load (or use) this public key using the openssl command-line tool.
If I generate the public key using the command-line tool ("|$ openssl
rsa -in private.pem -pubout > public.pem|"), I can use it and it works
like a charm.
Do you guys know how I can get this work ? Maybe another function ?
Thank you.
P.S: Here is the command line result when I try to use the generated
public key:
u...@computer:~$ openssl rsa -text -pubin -in public.pem -noout
unable to load Public Key
4379:error:0906D06C:PEM routines:PEM_read_bio:no start
line:pem_lib.c:647:Expecting: PUBLIC KEY
