Is it possible to build Diffie-Hellman parameters with 16384-bit key size?
I've tried it and it's taking more than 22 hours on a 3.4 GHz Xeon CPU (single core with hyperthreading, if it matters).
For comparison, it took about 37 min. using 4096-bit key size.
OS is OpenBSD 5.3.

Just for info, I tried with 8-kbit but ran into other limitations:
TLS_ERROR: BIO read tls_read_plaintext error: error:1408E098:SSL routines:SSL3_GET_MESSAGE:excessive message size
4-kbit is fine, I haven't tried with non-standard values between 4096 and 8192.
