It was failing to set the key in the ENCRYPT direction before encrypting.
This just happened to work for GCM and CCM.
After re-encrypting, compare the length to the expected ciphertext
length not the plaintext length. Again this just happens to work for
GCM and CCM since they do not perform any kind of padding.
The CA callback changes introduce mbedtls_calloc() and
mbedtls_free() to ssl_client2 and ssl_server2, which
wasn't defined unless MBEDTLS_PLATFORM_C was set.
So far, there were the following CRT verification functions:
- `mbedtls_x509_crt_verify()` -- no profile, no restartable ECC
- `mbedtls_x509_crt_verify_with_profile()` -- profile, no restartable ECC
- `mbedtls_x509_crt_verify_restartable()` -- profile, restartable ECC
all publicly declared and offering increasing functionality.
On the implementation-side,
- `mbedtls_x509_crt_verify()` resolves to
a call to `mbedtls_x509_crt_verify_with_profile()` setting
the profile to `NULL`, and
- `mbedtls_x509_crt_verify_with_profile()`
resolves to a call to ``mbedtls_x509_crt_verify_restartable()`
setting the ECC restart context to NULL.
This commit adds two more functions to this zoo:
- `mbedtls_x509_crt_verify_with_cb()`
- `x509_crt_verify_restartable_cb()`
Here, `mbedtls_x509_crt_verify_with_cb()` is similar to
`mbedtls_x509_crt_verify_with_profile()` but uses a CA callback
instead of a static CA list, and no restart context.
`x509_crt_verify_restartable_cb()` is similar to
`mbedtls_x509_crt_verify_restartable()` but allows to either use
a static list of trusted CAs _or_ a trusted CA callback.
On the implementation-side,
- the body of `mbedtls_x509_crt_verify_restartable()` is moved to
`x509_crt_verify_restartable_cb()`, and the new version of
`mbedtls_x509_crt_verify_restartable()` just resolves to
`x509_crt_verify_restartable_cb()` with the trusted CA callback
set to NULL.
- The new function `mbedtls_x509_crt_verify_with_cb()`
forward to `x509_crt_verify_restartable_cb()` with the restart
context set to `NULL`.
There's no change to the implementation yet, and in particular,
`mbedtls_x509_crt_verify_with_cb()` isn't yet usable.
This commit applies the documentation improvements noticed and applied
while adding the documentation for the new X.509 CRT verification API
mbedtls_x509_crt_verify_with_cb() to the existing verification APIs.
