ASYNCHRONOUS AEAD REQUEST HANDLE(9)

✨ ASYNCHRONOUS AEAD REQUEST HANDLE (9) ✨

okay so bestie, let me introduce you to the struct aead_request — literally the main character of the AEAD cipher operation. it's the data structure that holds all the pointers to the data you need. no cap. 💅

this little icon contains:

• the cipher handle (and bestie, it can be shared by multiple aead_request instances — it's giving reusable, sustainable, iconic) 🎀
• a pointer to plaintext
• a pointer to ciphertext
• the asynchronous callback function
• and all the other stuff you need, depending on the vibe 🦋

it basically acts as a handle to the aead_request_* API calls — like, in the same way that the AEAD handle relates to the crypto_aead_* API calls. iykyk. ✨
