f0fcb2d59f Symmetric changes to md4.go as for md5.go.
Use uint index variables in some cases instead
of int to enable strength reduction; this makes
it possible for the compiler to reduce % into
masks.

9d07d37f31 A couple of tighter loops.
(I was looking at this code accidentally because of some gofmt
issues and thought that one could write this more effectively.
You may have deliberately chosen not to use ranges here to make
the index range clearer. Just let me know.)

5a1d3323fe 1) Change default gofmt default settings for
parsing and printing to new syntax.

                  Use -oldparser to parse the old syntax,
                  use -oldprinter to print the old syntax.

               2) Change default gofmt formatting settings
                  to use tabs for indentation only and to use
                  spaces for alignment. This will make the code
                  alignment insensitive to an editor's tabwidth.

                  Use -spaces=false to use tabs for alignment.

               3) Manually changed src/exp/parser/parser_test.go
                  so that it doesn't try to parse the parser's
                  source files using the old syntax (they have
                  new syntax now).

               4) gofmt -w src misc test/bench

	       1st set of files.

6fc820729e go: makes it build for the case $GOROOT has whitespaces
the bash scripts and makefiles for building go didn't take into account
the fact $GOROOT / $GOBIN could both be directories containing whitespaces,
and was not possible to build it in such a situation.

this commit adjusts the various makefiles/scripts to make it aware of that
possibility, and now it builds successfully when using a path with whitespaces
as well.

Fixes #115.

ad05d29103 crypto/rsa: handle the case of non-coprime blinds.
We are dealing with the multiplicative group ℤ/pqℤ. Multiples of
either p or q are not members of the group since they cannot have an
inverse. (Such numbers are 0 in the subgroup ℤ/pℤ.)

With p and q of typical size (> 512 bits), the probability of a random
blind [1..pq-1] being a multiple of p or q is negligible. However, in
the unit tests, much smaller sizes are used and the event could occur.

This change checks the result of the ext GCD and deals with this case.

It also increases the size of p and q in the unit test as a large
number of the keys selected were p, q = 227,169.

bcce2987e0 crypto/rsa: fix blinding when using a null random source.
For testing it can be useful to use a null random source (one which
always returns zero) to remove non-determinism from the tests.
However, when performing RSA blinding, the random blind ends up being
zero and it's hard to reverse a multiplication by zero.
