Generate ECDSA key with OpenSSL
After the last NSA scandal I’ve found some time to read some texts about PFS and ECDSA keys lately. I always used RSA keys but wanted to give a try to ECDSA so I wanted to give it a try (test performance, etc). Here is how I’ve done it. Firstly find your favorite curve. A short tip about bit length and complexity could be found here. From it you will now that using 256 bit ECDSA key should be enough for next 10-20 years....
