spu2_digest_size(9)

💅 spu2_digest_size(9) — like, the Kernel API Manual page you actually wanna read

okay so bestie, welcome to the Kernel API Manual entry for spu2_digest_size 🎀 this one's short and sweet and honestly kinda iconic for it.

✨ NAME ✨

spu2_digest_size — figure out how big a hash digest you should expect the SPU to hand back to you 🫶

🌸 SYNOPSIS 🌸

u32 spu2_digest_size (u32 alg_digest_size , enum hash_alg alg , enum
hash_type htype );

🦋 ARGUMENTS 🦋

• alg_digest_size — the number of bytes in the final digest for the algo you're working with, fr fr. that's the size, that's the number.
• alg — the hash algorithm. which one? that's what this is. ✨
• htype — the type of hash operation (init, update, full, etc) 🧚 you know, the vibe of the operation.

👑 SEE ALSO 👑

bestie the cross-references go HARD, look at this list, it's giving main character energy. also heads up, this lives in the kernel file ./drivers/crypto/bcm/spu2.c 💖
