As per check-python-files.sh, added string documentation for
files and functions.
Modified for loops to use enumerate rather than range(len(
although as the same iteration index is used for multiple
lists it does not seem quite appropriate

- Replace uses of mbed and gnu with mbedtls and gnutls respectivley.
- Uses sys.exit() rather than exit()
- Rename format() as it is an inbuilt python function
- Add error information if incorrect arguments are passsed to

After every edge case to append which ciphers were being used
a call to translate_ciphers.py was being made.
Now a call to translate_ciphers are made at the end of every
function where ciphersuite names are being added. This occurs
3 times. 1 for MBedTLS, GNUTLS and OpenSSL. 1 for MBedTLS and
OpenSSL and another 1 for MBedTLS and GNUTLS.

In translate_ciphers.py there were 2 format functions that were
virtually identical and a check was made beforehand to decide
which one to call. Now the check is made inside a single function
to reduce duplicate code

Replace the OpenSSL $O_CIPHERS and GNU $G_CIPHERS declarations
with calls to translate_ciphersuite.py
Declared a new variable for each sublist $CIPHERS which is appended
to MBedTLS $M_CIPHERS and translated+appended to the OpenSSL and GNU
lists.

Changes to pass tests/scripts/check_files.py
-Add missing new line at end of each file
-Remove any trailing whitespaces
-Added file shebang comments
Added license info and purpose of file descriptions. The 2 test_translate...
files may not be stay later down the line, but incase they do become
permanent, it is good to add the appropriate comments now.

To be used by compat.sh, the files were moved to the same directory.
The files were also renamed to be distinguishable aside from their

Added formatting functions to translate_ciphersuite.py to take a string
of multiple ciphersuite names, in the current compat.sh and output the
translated ciphersuite names in the same format
Created test_translate.sh which uses samples from compat.sh to compare
against the translated versions to ensure the translations are produced
in the correct format

Moved the test over to a seperate file, where I can start experimenting with
how the script will be called.
Commented and improved the translation functions. They should be more readable,
however I added comments anyway to quickly identify every step involved with
te translation from MBedTLS to GNU or OpenSSL
Signed-off-by: Joe Subbiani <joe.subbiani@arm.com>
Created 2 functions
- translate_gnu()
- translate_ossl()
Each function takes a parameter `m_cipher` (expected in the MBedTLS naming
standard), and through a series of edge cases/replaces, modifies the
ciphersuite name to match the GNU and OpenSSL naming conventions respectively.
This will serve as to maintain a single list that can be translated, rather
than maintaining 3 lists for OpenSSL and GNU also.
This commit serves as a checkpoint, and the program will be cleaned up in the
future.
The program currently runs a series of tests to check every given ciphersuite name
combination in compat.sh to ensure they are translated correctly.
Some OpenSSL names appear to have typos and as such have been corrected in
this program until I have recieved more information. The errors were commented
out to keep note of.

v3.7.2 introduces DISABLE_TLS13_COMPAT_MODE. That can be

Where possible, just stick to size_t.

We previously had tests for not sending enough (additional) data, but
were missing tests for sending too much. I have added these to the state
tests, as I don't think this is complex enough to deserve a standalone
test.

Most supported ciphers have a 128-bit, 192-bit or 256-bit keys. List the

This was already documented for mbedtls_md_info_t. Also document it for
mbedtls_pk_info_t (where it's fairly obvious since the structure is not
defined in a public header) and for mbedtls_cipher_info_t (where it's not
obvious since the structure is defined in a public header).

The structures mbedtls_x509_time, mbedtls_x509_crl_entry, mbedtls_x509_crl,
mbedtls_x509_crt, mbedtls_x509_san_other_name,

On platforms with BSD-like sockets, it is useful for applications to have
access to the underlying file descriptor so that they can use functions like
select() and poll().
Do not promise that the field will exist on other platforms such as
Windows (where the type and name of the field are technically wrong because
Windows socket handles are actually not file descriptors).

Add functions to read the type, mode, name and key_bitlen fields from
mbedtls_cipher_info_t. These are the fields that applications are most
likely to care about.
TLS code also uses iv_size and block_size, which it might make sense to
expose, but most applications shouldn't need those, so I'm not exposing them
for now.
Call the new functions in unit tests, so they're at least smoke-tested.
