STRUCT BPF_CRYPTO_PARAMS(9)

🌸 NAME 🌸

Hiii bestie 💖 welcome to the struct bpf_crypto_params(9) page of the Kernel API Manual. This is the BPF crypto initialization parameters structure — the struct that holds your BPF crypto init params. Iconic, honestly. ✨

💫 SYNOPSIS 💫

Here's the struct in all its glory, exactly as it appears:

       struct bpf_crypto_params {
           char type[14];
           u8 reserved[2];
           char algo[128];
           u8 key[256];
           u32 key_len;
           u32 authsize;
        };

No notes, just vibes ✅.

🧚 Members 🧚

• type — the string of crypto operation type. 🎀
• reserved — reserved member, will be reused for more options in future. Values: 0. Leave this one alone, bestie 🙅♀️.
• algo — the string of algorithm to initialize. 🧪✨
• key — the cipher key used to init crypto algorithm. 🔑
• key_len — the length of cipher key. 📏
• authsize — the length of authentication tag used by algorithm. 🏷️
