Expand description

Abstraction for cryptographic signing operations.

Implementations handle key storage, signing, and verification. The default LocalKeyProvider stores keys on-disk; future implementations can integrate with external KMS services.

Required Methods§

Source

fn sign<'life0, 'life1, 'async_trait>( &'life0 self, data: &'life1 [u8], ) -> Pin<Box<dyn Future<Output = Result<Vec<u8>, CompileError>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Sign the given data and return the signature bytes.

Source

fn verify<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, data: &'life1 [u8], signature: &'life2 [u8], ) -> Pin<Box<dyn Future<Output = Result<bool, CompileError>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait,

Verify a signature against the given data.

Source

fn public_key_bytes<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = Result<Vec<u8>, CompileError>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait,

Return the public key bytes (for embedding in descriptors).

Provided Methods§

Source

fn supports_local_delegation(&self) -> bool

Whether this captured provider signs entirely in memory, without fresh key lookup, filesystem access, networking or another ambient credential. Unknown/KMS implementations need an explicit delegated binding first.

Dyn Compatibility§

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
