Expand description

Encrypted content information RFC 5652 § 6

EncryptedContentInfo ::= SEQUENCE {
  contentType ContentType,
  contentEncryptionAlgorithm
    ContentEncryptionAlgorithmIdentifier,
  encryptedContent
    [0] IMPLICIT EncryptedContent OPTIONAL }

ContentEncryptionAlgorithmIdentifier ::=
  AlgorithmIdentifier

EncryptedContent ::= OCTET STRING

The fields of type EncryptedContentInfo have the following meanings:

content_type indicates the type of content.
content_encryption_algorithm identifies the content-encryption algorithm (and any associated parameters) under which the content is encrypted. This algorithm is the same for all recipients.
encrypted_content is the result of encrypting the content. The field is optional, and if the field is not present, its intended value must be supplied by other means.

Fields

content_type: ContentType

indicates the type of content.

content_encryption_algorithm: AlgorithmIdentifier<'a>

identifies the content-encryption algorithm (and any associated parameters) under which the content is encrypted.

encrypted_content: Option<&'a [u8]>

the encrypted contents; when not present, its intended value must be supplied by other means.
