Struct SignerBuilder 

pub struct SignerBuilder<'a> { /* private fields */ }

Builder type to construct an entity that will sign some data.

Instances will be attached to SignedDataBuilder instances where they will sign data using configured settings.

Implementations

impl<'a> SignerBuilder<'a>

pub fn new( signing_key: &'a dyn KeyInfoSigner, signing_certificate: CapturedX509Certificate, ) -> Self

Construct a new entity that will sign content.

An entity is constructed from a signing key, which is mandatory.

pub fn new_with_signer_identifier( signing_key: &'a dyn KeyInfoSigner, signer_identifier: SignerIdentifier, ) -> Self

Construct a new entity that will sign content.

An entity is constructed from a signing key and signer identifier, which are mandatory.

pub fn signature_algorithm(&self) -> Result<SignatureAlgorithm, CmsError>

Obtain the signature algorithm used by the signing key.

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

Define the content to use to calculate the message-id attribute.

In most cases, this is never called and the encapsulated content embedded within the generated message is used. However, some users omit storing the data inline and instead use a message-id digest calculated from a different source. This defines that different source.

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

Define the content type of the signed content.

pub fn signed_attribute(self, typ: Oid, values: Vec<AttributeValue>) -> Self

Add an additional attribute to sign.

pub fn signed_attribute_octet_string(self, typ: Oid, data: &[u8]) -> Self

Add an additional OctetString signed attribute.

This is a helper for converting a byte slice to an OctetString and AttributeValue without having to go through low-level ASN.1 code.

Trait Implementations

impl<'a> Clone for SignerBuilder<'a>

fn clone(&self) -> SignerBuilder<'a>

Returns a duplicate of the value.

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

Performs copy-assignment from source.
