Detailed Description
Internal cipher sponge state associated with a buffer holding for less-than-rate updates.
Used for the Init-Update-Final implementation.
Field Documentation
◆ sponge
| ascon_sponge_t ascon_bufstate::sponge |
Cipher sponge state.
◆ buffer
| uint8_t ascon_bufstate::buffer[ASCON_DOUBLE_RATE] |
Buffer caching the less-than-rate long input between update calls.
◆ buffer_len
| uint8_t ascon_bufstate::buffer_len |
Currently used bytes of the buffer.
◆ flow_state
| uint8_t ascon_bufstate::flow_state |
State of the order of Init-Update-Final function calls, checked to know when to finalise the associated data processing and for the runtime assertions on the correct order of the functions.

Note: this variable is not semantically relevant in THIS struct, as it should belong in the struct ascon_aead_ctx_t, but by having it here we spare bytes of padding (7 on 64-bit systems, 3 on 32-bit, 1 on 16-bit) at the end of the struct ascon_aead_ctx_t, by using some of the padding space this struct anyway has.
◆ pad
| uint8_t ascon_bufstate::pad[6] |
Unused padding to the next uint64_t (sponge.x0 or ctx.k0) to avoid errors when compiling with -Wpadding on any platform.
