The API follows guidelines of https://www.python.org/dev/peps/pep-0272/,
but is optimized for code size, with the idea that full PEP 0272
compatibility can be added with a simple Python wrapper mode.
The naming of the module follows (u)hashlib pattern.
At the bare minimum, this module is expected to provide:
* AES128, ECB (i.e. "null") mode, encrypt only
Implementation in this commit is based on axTLS routines, and implements
following:
* AES 128 and 256
* ECB and CBC modes
* encrypt and decrypt
The unix coverage build is now switched fully to the VFS implementation, ie
the uos module is the uos_vfs module. For example, one can now sandbox uPy
to their home directory via:
$ ./micropython_coverage
>>> import uos
>>> uos.umount('/') # unmount existing root VFS
>>> vfs = uos.VfsPosix('/home/user') # create new POSIX VFS
>>> uos.mount(vfs, '/') # mount new POSIX VFS at root
Some filesystem/OS features may no longer work with the coverage build due
to this change, and these need to be gradually fixed.
The standard unix port remains unchanged, it still uses the traditional uos
module which directly accesses the underlying host filesystem.
If, for class X, X.__add__(Y) doesn't exist (or returns NotImplemented),
try Y.__radd__(X) instead.
This patch could be simpler, but requires undoing operand swap and
operation switch to get non-confusing error message in case __radd__
doesn't exist.
This is to keep the top-level directory clean, to make it clear what is
core and what is a port, and to allow the repository to grow with new ports
in a sustainable way.
