-### `AllocatedBuffer`
-
-The `AllocatedBuffer` utility is defined in `allocated_buffer.h` and is not
-specific to `src/crypto`. It is used extensively within `src/crypto` to hold
-allocated data that is intended to be output in response to various
-crypto functions (generated hash values, or ciphertext, for instance).

-_Currently, we are working to transition away from using `AllocatedBuffer`

-New uses of `AllocatedBuffer` should be avoided if possible._

 Most crypto operations involve the use of keys -- cryptographic inputs
