If you want to use the RSA stuff for crypto keys:
|
|
|
|
- Get RSAREF or RSAEURO.
|
|
- - Unpack it in the top-level source directory of the NTP distribution
|
|
in a directory named rsaref2 or rsaeuro1, respectively
|
|
(You should see directories like ports, rsaref2, scripts)
|
|
|
|
Make sure rsa.c has the security patch applied - a copy of it is at the
|
|
end of this file.
|
|
|
|
When you run configure, the Right Thing will happen.
|
|
|
|
Be advised that the RSA DES code is not quite as portable os one might
|
|
wish for. In particular, DES under NTP will only work between machines
|
|
of the same "endianness".
|
|
|
|
Dave would prefer that new/alternative encryption schemes follow the
|
|
RSA API.
