All uses of `get_random()` were in the form of:
`&get_random(vec![0u8; SIZE])`
with `SIZE` being a constant.
Building a `Vec` is unnecessary for two reasons. First, it uses a
very short-lived dynamic memory allocation. Second, a `Vec` is a
resizable object, which is useless in those context when random
data have a fixed size and will only be read.
`get_random_bytes()` takes a constant as a generic parameter and
returns an array with the requested number of random bytes.
Stack safety analysis: the random bytes will be allocated on the
caller stack for a very short time (until the encoding function has
been called on the data). In some cases, the random bytes take
less room than the `Vec` did (a `Vec` is 24 bytes on a 64 bit
computer). The maximum used size is 180 bytes, which makes it
for 0.008% of the default stack size for a Rust thread (2MiB),
so this is a non-issue.
Also, most of the uses of those random bytes are to encode them
using an `Encoding`. The function `crypto::encode_random_bytes()`
generates random bytes and encode them with the provided
`Encoding`, leading to code deduplication.
`generate_id()` has also been converted to use a constant generic
parameter as well since the length of the requested String is always
a constant.
The current limit of 19 is an artifact of the implementation, which can be
easily rewritten in terms of a more general string generation function.
The new limit is 255 (max value of a `u8`); using a larger type would
probably be overkill.
- Updated rust nightly
- Updated depenencies
- Removed unicode support for regex (less dependencies)
- Fixed dependency and nightly changes/deprications
- Some mail changes for less spam point triggering
TODO:
- At the moment each user needs to configure a DUO application and input the API keys, we need to check if multiple users can register with the same keys correctly and if so we could implement a global setting.
- Sometimes the Duo frame doesn't load correctly, but canceling, reloading the page and logging in again seems to fix it for me.
