ElGamal needs a very strong RNG. Cryptographic strongs random numbers
are used in amyn places: As initialization vectors, for padding and
to create the session key.

There is a section about cross-compiling in INSTALL.

Symmetric ciphers are more secure than asymmetric ciphers. One reason
is that you can more easily change the key.
What about adding a serial number to the key for each customer.

Please see Peter Gutmann's paper about "practically strong random
numbers"; this scheme should be used.
