Can anyone point me in the direction of a tutorial
that covers the best (or at least well recommended) way
of implementing RSA encryption. Please not code examples
that deal with small strings that produce byte arrays of 116 elements
or less are not much use as they fall over when dealing with large strings.

Thanks

strings.

RSA isn't used to encrypt large strings or byte arrays. In fact, the maximum
number of bytes that can be encrypted with RSA depends on the key size that
you use [117 bytes with a 1024 bit key, 245 bytes with a 2048 bit key, etc].
RSA is typically used to encrypt the key of a symmetric bulk cipher, such as
TripleDES or Rijndael. The actual data is then encrypted with that symmetric
algorithm using the RSA encrypted key.

What is the most robust of the symmetric algorythms to do bulk ciphering.

Rijndael is the best and the fastest one, and it is written in managed code.
