Struct SigningKey 

pub struct SigningKey { /* private fields */ }

RSA 私钥（CRT 参数；Drop 零化秘密分量）。

Implementations

impl SigningKey

pub const APPROVAL: Approval = crate::Approval::Approved

本算法在 FIPS 140-3 下的批准状态。

pub fn from_pkcs8_der(der: &[u8]) -> Result<Self, Error>

从 PKCS#8 DER（内层 PKCS#1 RSAPrivateKey）解析。模长 < 2048 位 返回 Error::Unsupported。

pub fn from_pkcs1_der(der: &[u8]) -> Result<Self, Error>

解析 PKCS#1 RSAPrivateKey DER 并做结构一致性校验 （rustls KeyProvider 的 PKCS#1 入口）。

pub fn sign_pss(&self, hash_bits: u16, message: &[u8]) -> Result<Vec<u8>, Error>

RSA-PSS 签名（salt 长度 = 哈希长度；TLS 1.3 使用）。

pub fn sign_pkcs1v15( &self, hash_bits: u16, message: &[u8], ) -> Result<Vec<u8>, Error>

RSA PKCS#1 v1.5 签名（TLS 1.2 遗留套件与证书链验证使用）。

Trait Implementations

impl Clone for SigningKey

fn clone(&self) -> SigningKey

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for SigningKey

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Drop for SigningKey

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.
