# `Cmsex.SignedData`
[🔗](https://github.com/openspb/cmsex/blob/v0.1.0/lib/cmsex/signed_data.ex#L1)

A SignedData message, as `Cmsex.decode/2` reads it (RFC 5652, 5).
Reading checks the structure only; `Cmsex.verify/2` checks the
signatures.

Fields:

  * `:version` - the version written in the message.
  * `:content_type` - the type of the signed content (eContentType), as
    a name of `Cmsex.OID`, such as `:data` or `:tst_info`, or an OID.
  * `:content` - the signed content, or `nil` for a detached signature.
    It is the value of the eContent OCTET STRING, its segments joined
    when the message was written in BER. For a PKCS #7 message whose
    content is not an OCTET STRING (RFC 5652, 5.2.1), it is the content
    octets of that value, which is what the signature covers.
  * `:pkcs7_content` - for such a PKCS #7 message, the whole encoding of
    the content; `nil` otherwise.
  * `:digest_algorithms` - the digestAlgorithms field, as names or OIDs.
    Verification does not depend on it.
  * `:certificates` - the X.509 certificates of the message, in DER, in
    the order of the message. They are not trusted for being there.
  * `:other_certificates` - the other choices of CertificateChoices
    (attribute certificates, other formats), each as received.
  * `:crls` - the certificate revocation lists, in DER.
  * `:other_crls` - other revocation information (RFC 5652, 10.2.1),
    each as received.
  * `:signer_infos` - the signers, a list of `Cmsex.SignerInfo`. Empty in
    a certificate bundle.
  * `:deviations` - what the library tolerated when reading, against
    RFC 5652: `:signed_data_version` when the version is not the one
    the fields call for (section 5.1). The signers have their own.
