This script includes a `keygen' target for regenerating RSA and DSA host keys,
and invokes this if these keys are not present when sshd is started up.
routines from OpenSSL. Speeds up DSA significantly. A similar
gain should also be seen for RSA.

and decrypt from OpenSSL. Right now we only build the 586 version,
but eventually we will be able to build the 686 version based on a
CPP flag defined as a result of using `cc -mcpu=pentiumpro'.
We don't build the assembly version of BF_cbc_encrypt(), as it would
have to be rewritten to be PIC.
Performance difference is quite noticeable.

implementations will fail if count is passed as zero (they are set up in
a do-{}-while structure).
