Module provider 

Provider-neutral cryptographic operations.

XML parsing and protocol orchestration depend on this contract rather than concrete cryptographic crates. Secret-bearing keys remain opaque behind operation-specific handles; this provider owns primitive dispatch and randomness.

Structs

KdfParameters

Provider-neutral parameters for a key-derivation operation.

KeyAgreementParameters

Provider-neutral parameters for an asymmetric key-agreement operation.

RustCryptoProvider

Pure-Rust provider backed by RustCrypto crates.

RustCryptoRsaPrivateKey

Opaque RSA private-key handle for the built-in RustCrypto provider.

RustCryptoRsaPublicKey

Opaque RSA public-key handle for the built-in RustCrypto provider.

Enums

ProviderCapability

One exact provider capability, including operation-specific parameters.

ProviderError

Failure returned by a cryptographic provider.

ProviderInputError

Structured invalid-input reasons returned by cryptographic providers.

ProviderOperation

A cryptographic operation advertised by a provider.

X509SignatureAlgorithm

Provider-neutral X.509 certificate and CRL signature parameters.

Statics

RUST_CRYPTO_PROVIDER

Process-wide immutable default provider. It contains no mutable state or keys.

Traits

CryptoProvider

Stateless provider operations used by the XML Security pipelines.

KeyAgreementKey

Opaque private-key handle used for provider-defined key agreement.

KeyRecoveryKey

Opaque private-key handle used to recover transported key bytes.

KeyTransportKey

Opaque public-key handle used for asymmetric key transport.

Functions

default_provider

Borrow the pure-Rust default provider.
