Struct cryptographic_message_syntax::SignedDataBuilder

pub struct SignedDataBuilder<'a> { /* fields omitted */ }

Entity for incrementally deriving a SignedData primitive.

Use this type for generating an RFC 5652 payload for signed data.

Implementations

impl<'a> SignedDataBuilder<'a>

pub fn signed_content(self, data: Vec<u8>) -> Self

Define the content to sign.

This content will be embedded in the generated payload.

pub fn signer(self, signer: SignerBuilder<'a>) -> Self

Add a signer.

The signer is the thing generating the cryptographic signature over data to be signed.

pub fn certificate(self, cert: CapturedX509Certificate) -> Self

Add a certificate defined by our crate’s Certificate type.

pub fn certificates(
    self,
    certs: impl Iterator<Item = CapturedX509Certificate>
) -> Self

Add multiple certificates to the certificates chain.

pub fn content_type(self, oid: Oid) -> Self

Force the OID for the ContentInfo.contentType field.

pub fn build_der(&self) -> Result<Vec<u8>, CmsError>

Construct a DER-encoded ASN.1 document containing a SignedData object.

RFC 5652 says SignedData is BER encoded. However, DER is a stricter subset of BER. DER encodings are valid BER. So producing DER encoded data is perfectly valid. We choose to go with the more well-defined encoding format.

Trait Implementations

impl<'a> Default for SignedDataBuilder<'a>

fn default() -> Self

Returns the “default value” for a type.
