get public key from private key with python OpenSSL
openssl, pyopenssl, python
Solution
If
cert = crypto.dump_certificate(crypto.FILETYPE_PEM, k)
doesn't do what you want, then it doesn't look like `pyOpenSSL` supports public key dumping. There is an unmerged branch here that adds that functionality but I can't claim that it does what is purports.
Problem
Well, I generate a private key with pyOpenSSL as follows: ``` from OpenSSL import crypto k = crypto.PKey() k.generate_key(crypto.TYPE_RSA, 2048) print crypto.dump_privatekey(crypto.FILETYPE_PEM, k) ``` How do I get the public key string from it? I've still not found what method of this library does it. Thanks
