crypto_poly1305_setdesckey

函数名称：Poly1305 requires a unique key for each tag, which implies that we can't set* it on the tfm that gets accessed by multiple users simultaneously. Instead we* expect the key as the first 32 bytes in the update() call.

函数原型：static inline unsigned int crypto_poly1305_setdesckey(struct poly1305_desc_ctx *dctx, const u8 *src, unsigned int srclen)

返回类型：unsigned int

参数：

类型	参数	名称
struct poly1305_desc_ctx *	dctx
const u8 *	src
unsigned int	srclen

如果非 whether s[] has been set 则

如果非 how many keys have been set in r[] 且srclen大于等于POLY1305_BLOCK_SIZE则

poly1305_core_setkey( key , src)

src加等于POLY1305_BLOCK_SIZE

srclen减等于POLY1305_BLOCK_SIZE

how many keys have been set in r[] 等于1

如果srclen大于等于POLY1305_BLOCK_SIZE则

finalize key [0]等于get_unaligned_le32(src + 0)

finalize key [1]等于get_unaligned_le32(src + 4)

finalize key [2]等于get_unaligned_le32(src + 8)

finalize key [3]等于get_unaligned_le32(src + 12)

src加等于POLY1305_BLOCK_SIZE

srclen减等于POLY1305_BLOCK_SIZE

whether s[] has been set = true

返回:srclen
