From 8a9208612eec8ddae4c418485d848ecfa0613699 Mon Sep 17 00:00:00 2001 From: Anton Kling Date: Mon, 30 Oct 2023 22:12:14 +0100 Subject: Meta: Move kernel and userland to their own folders. This is to allow both the kernel and the userland to share certain header files and to make the folder structure a bit more clear. --- kernel/crypto/ChaCha20/chacha20.h | 15 +++++++++++++++ 1 file changed, 15 insertions(+) create mode 100644 kernel/crypto/ChaCha20/chacha20.h (limited to 'kernel/crypto/ChaCha20/chacha20.h') diff --git a/kernel/crypto/ChaCha20/chacha20.h b/kernel/crypto/ChaCha20/chacha20.h new file mode 100644 index 0000000..17532f3 --- /dev/null +++ b/kernel/crypto/ChaCha20/chacha20.h @@ -0,0 +1,15 @@ +#ifndef CHACHA20_H +#define CHACHA20_H +#include + +#define KEY 4 +#define KEY_SIZE 8*sizeof(uint32_t) +#define COUNT 12 +#define COUNT_SIZE sizeof(uint32_t) +#define COUNT_MAX (0x100000000-1) // 2^32 - 1 +#define NONCE 13 +#define NONCE_SIZE 2*sizeof(uint32_t) +#define BLOCK_SIZE 16*sizeof(uint32_t) + +void chacha_block(uint32_t out[16], uint32_t const in[16]); +#endif -- cgit v1.2.3
