aescfb_encrypt(9)

💖 NAME 💖

Okay bestie, welcome to aescfb_encrypt(9) from the Kernel API Manual ✨ — this icon literally performs AES-CFB encryption on a block of data. Periodt.

✨ SYNOPSIS ✨

void aescfb_encrypt (const struct aes_enckey *key , u8 *dst , const u8
       *src , int len , const u8 iv[AES_BLOCK_SIZE] );

🎀 ARGUMENTS 🎀

• key — the AES-CFB key schedule 🔑
• dst — pointer to the ciphertext output buffer 💅
• src — pointer to the plaintext; yes, it may equal dst for encryption in place 🫶
• len — the size in bytes of the plaintext and ciphertext 📏
• iv — the initialization vector (IV) to use for this block of data 🌀
