* Default leaf key RSA keysize in bits.
*
* While implementations still generally accepted leaf keys of 1024 bits in
* size, we used 1024 for leaf keys. As implementations are starting to sunset
* 1024 bit RSA not only for CA keys, but also for leaf keys, we now use a 2048
* bit key size for the leaf cert key in order to maximize interoperability in
* default config.
*
* Users who want a different size, for example 1024 bit RSA for performance,
* can always use their own pre-generated leaf key using the -K option instead
* of generating one automatically.
*
* Refer to the following resources on key sizes accepted by different
* implementations. Note that OpenSSL security level restrictions potentially
* apply to both sslsplit and all of the clients and servers using OpenSSL.
