Instead of every padding verification implementation and every padding
encoding implementation doing the digesting, have `sign()` and
`verify()` to it themselves.
Expose `RSAEncoding` in the public API so that users of *ring* can use
it in type signatures. Add an "RSA" prefix to the exported types, since
they will be exported from `ring::signature`. Modify RSA tests to use
only the public API so as to ensure that enough of the API is public.
Besides improving type safety generally, this fixes a bug in RSA PSS
signing where the wrong value of `mod_bits` was being passed to
`Encoding::encode()`.
- Refactor Encoding trait to be randomised.
- Add RSA-PSS signing test cases.
I agree to license my contributions to each file under the terms given
at the top of each file I changed.
At the time the code was written, I didn't know `mut self` was an
option.
With the new move semanticsfor `into_raw()`, more of the complexity of
the pointer handling can be removed as there's no potential for any
null dereference.
This is a first step toward fully-automated formatting. A custom format
is used, primarily to tell rustfmt to wrap at column 80(-ish) instead of
column 100(-ish), and to use more compact styles.
Many rustfmt suggestions for rewrapping function calls were ignored
because they did not result in the minimum number of lines and/or
because I'm still unsure the best way to format a long chain. Some
suggestions for reformatting macros were ignored because they ruined
the indention. Some other suggestions were ignored because they seemed
like bugs and/or seemed to make things clearly worse.
Further work is planned, in order to make the formatting fully
automatic.
