Calling `mbedtls_cipher_finish()` is mandatory for all multi-part operations
|
|
----------------------------------------------------------------------------
|
|
|
|
This only affects people who use the cipher module to perform AEAD operations
|
|
using the multi-part API.
|
|
|
|
Previously, the documentation didn't state explicitly if it was OK to call
|
|
`mbedtls_cipher_check_tag()` or `mbedtls_cipher_write_tag()` directly after
|
|
the last call to `mbedtls_cipher_update()` - that is, without calling
|
|
`mbedtls_cipher_finish()` in-between. If you code was missing that call,
|
|
please add it and be prepared to get as much as 15 bytes of output.
|
|
|
|
Currently the output is always 0 bytes, but it may be more when alternative
|
|
implementations of the underlying primitives are in use, or with future
|
|
versions of the library.
