A Darchitecture.rst8 cipher types:
131 cipher allocation API calls
154 - aead for AEAD cipher type
178 When allocating a cipher handle, the caller only specifies the cipher
229 cipher implementation for the given cipher name. That means, even when a

266 the AES cipher are all merged into one cipher implementation registered
278 implemented in the cipher.

58 a cipher handle:
60 1. Initialization of a cipher handle.
62 2. Execution of all intended cipher operations applicable for the handle
63 where the cipher handle must be furnished to every API call.
65 3. Destruction of a cipher handle.
