There was a problem hiding this comment. There needs to be an alloc function such that the caller/user doesn't need to know the magic numbers here.

There was a problem hiding this comment. I can't think of a convenient way to add such function. I don't seem to be able to alloc/dealloc memory buffers at Low*-level, these functionalities are specific to this library which only utilizes NI and CT64 function from inside EverCrypt functions that the user are supposed to use instead.

There was a problem hiding this comment. You can look at other alloc functions like hacl-packages/src/Hacl_Hash_SHA3.c Line 175 in 81303b8 hacl-packages/src/Hacl_Hash_Blake2s_128.c Line 480 in 81303b8

There was a problem hiding this comment. I implemented malloc/free for AES_GCM context on hacl side mamonet/hacl-star@c9880f1 |

There was a problem hiding this comment. Similarly to the alloc, do we need a free function here. |
