Does the file in question contain something along these lines:
[ The below key was newly generated for this message, is of no value at
all, and the pass-phrase is 'foobar' for anyone who wants to 'crack' it. ]

Perhaps your file does not contain an RSA private key.

Openssl Rsa Generate Key
ftp commander pro mac download The main problem is that I'm quite new to C, and the OpenSSL documentation is not clear enough for me, I've tried using Reading and writing rsa keys to a pem file in C, but I don't quite understand it. For example, how does the creatersakey function creates both the private and the public? Generate an RSA private key using default parameters: openssl genpkey -algorithm RSA -out key.pem. Encrypt output private key using 128 bit AES and the passphrase 'hello': openssl genpkey -algorithm RSA -out key.pem -aes-128-cbc -pass pass:hello. Generate a 2048 bit RSA key using 3 as the public exponent.
