Struct DeviceSignature 

pub struct DeviceSignature(/* private fields */);

Public types of device identity.

Device identity lives in qualia_dik — an independent, reusable crate that any project needing “a pair of P-256 identity keys in platform hardware” can use without accepting this crate’s vault format or sync protocol. They are re-exported here so that downstream code does not have to depend on both crates.

DevicePublicKey and DeviceSignature are not secret — they are meant to be printed on QR codes, written to logs, and propagated between devices — so they are exported separately from the secret types, which makes it visible in an import list which types may be printed freely. 设备身份签名（ECDSA P-256 原始 r||s，64 字节）。

Implementations

impl DeviceSignature

pub fn from_bytes(bytes: &[u8]) -> Result<DeviceSignature, Error>

从原始 r||s 构造。

不在这里做范围校验：r/s 必须是 [1, n-1] 内的整数这一约束由 验签负责，而验签本来就要重新计算并比对，重复一次没有意义。构造这个 类型只是说「这 64 个字节声称是一个签名」。

错误

长度不是 64 字节时返回 Error::DeviceSignatureInvalid。

pub const fn as_bytes(&self) -> &[u8; 64]

取原始 r||s 字节。
