- * @access public
- * @internal The most naive approach to modular exponentiation has very unreasonable requirements, and
- * and although the approach involving repeated squaring does vastly better, it, too, is impractical
- * for our purposes. The reason being that division - by far the most complicated and time-consuming
- * of the basic operations (eg. +,-,*,/) - occurs multiple times within it.
- *
- * Modular reductions resolve this issue. Although an individual modular reduction takes more time
- * then an individual division, when performed in succession (with the same modulo), they're a lot faster.
- *
- * The two most commonly used modular reductions are Barrett and Montgomery reduction. Montgomery reduction,
- * although faster, only works when the gcd of the modulo and of the base being used is 1. In RSA, when the
- * base is a power of two, the modulo - a product of two primes - is always going to have a gcd of 1 (because
- * the product of two odd numbers is odd), but what about when RSA isn't used?
- *
- * In contrast, Barrett reduction has no such constraint. As such, some bigint implementations perform a
- * Barrett reduction after every operation in the modpow function. Others perform Barrett reductions when the
- * modulo is even and Montgomery reductions when the modulo is odd. BigInteger.java's modPow method, however,
- * uses a trick involving the Chinese Remainder Theorem to factor the even modulo into two numbers - one odd and
- * the other, a power of two - and recombine them, later. This is the method that this modPow function uses.
- * {@link http://islab.oregonstate.edu/papers/j34monex.pdf Montgomery Reduction with Even Modulus} elaborates.

- A Note on SFTPv4/5/6 support:

-
- "If the client wishes to interoperate with servers that support noncontiguous version
- numbers it SHOULD send '3'"
-
- Given that the server only sends its version number after the client has already done so, the above
- seems to be suggesting that v3 should be the default version. This makes sense given that v3 is the
- most popular.
-
- <http://tools.ietf.org/html/draft-ietf-secsh-filexfer-13#section-5.5> states the following;
-
- "If the server did not send the "versions" extension, or the version-from-list was not included, the
- server MAY send a status response describing the failure, but MUST then close the channel without
- processing any further requests."
-
- So what do you do if you have a client whose initial SSH_FXP_INIT packet says it implements v3 and
- a server whose initial SSH_FXP_VERSION reply says it implements v4 and only v4? If it only implements
- v4, the "versions" extension is likely not going to have been sent so version re-negotiation as discussed
- in draft-ietf-secsh-filexfer-13 would be quite impossible. As such, what sftp would do is close the
- channel and reopen it with a new and updated SSH_FXP_INIT packet.
