 The following API functions, and supporting types, are candidates for
 inclusion in the Cipher light API, with limited features as above:
 ```
-mbedtls_cipher_info_from_type
+mbedtls_cipher_info_from_values
 mbedtls_cipher_info_get_block_size
 
 mbedtls_cipher_init
 mbedtls_cipher_setup
 mbedtls_cipher_setkey
-mbedtls_cipher_crypt
 mbedtls_cipher_free
 
 mbedtls_cipher_update
-(mbedtls_cipher_finish)
 ```
 
 Note: `mbedtls_cipher_info_get_block_size()` can be hard-coded to return 16,
 as all three supported block ciphers have the same block size (DES was
 excluded).
 
-Note: `mbedtls_cipher_finish()` is not required by any of the modules using
-Cipher light, but it might be convenient to include it anyway as it's used in
-the implementation of `mbedtls_cipher_crypt()`.

 This is likely to come in the future, but has not been defined yet.
