Hello,
I have the public key certificate in
cert.pem and I want to
extract the public key and store it in file
pubkey.pem. I did
it with the following command: (openssl v.0.9.7a)
openssl x509 -in cert.pem -pubkey -noout > pubkey.pem
However the following command did the strange things:
openssl x509 -in cert.pem -pubkey -noout -out pubkey.pem
It ignored the "-out pubkey" and printed the public key to STDOUT.
Also, the -pubkey option hasn't been listed in the list of options of
x509 command (
http://www.openssl.org/docs/apps/x509.html#). Maybe it
corresponds to the latest openssl v.0.9.8, but that option hasn't been
listed also in "man page" for openssl v.0.9.7a.
Can anybody explain this behaviour?
Thanks,
Arsen.
