Struct cryptographic_message_syntax::SignedData [−][src]
Represents a CMS SignedData structure.
This is the high-level type representing a CMS signature of some data. It contains a description of what was signed, the cryptographic signature of what was signed, and likely the X.509 certificate chain for the signing key.
This is a high-level data structure that ultimately gets (de)serialized from/to ASN.1. It exists to facilitate common interactions with the low-level ASN.1 without exposing the complexity of ASN.1.
Implementations
impl SignedData
[src]
pub fn parse_ber(data: &[u8]) -> Result<Self, CmsError>
[src]
Construct an instance by parsing BER data.
pub fn message_digest_with_algorithm(&self, alg: DigestAlgorithm) -> Digest
[src]
Compute the digest of the encapsulated content using a specified algorithm.
The returned value is likely used as the message-digest
attribute type
for use within signed attributes.
You can get the raw bytes of the digest by calling its .as_ref()
.
pub fn signed_content(&self) -> Option<&[u8]>
[src]
Obtain encapsulated content that was signed.
This is the defined encapContentInfo cContent
value.
pub fn certificates(&self) -> Box<dyn Iterator<Item = &Certificate>>
[src]
pub fn signers(&self) -> impl Iterator<Item = &SignerInfo>
[src]
Obtain signing information attached to this instance.
Each iterated value represents an entity that cryptographically signed the content. Use these objects to validate the signed data.
