Struct EncryptedData 

pub struct EncryptedData {
    pub recipients: SequenceOfRecipientInfo,
    pub ciphertext: SymmetricCiphertext,
}

Encodes data encrypted to one or more recipients using their public or symmetric keys as specified in 5.3.4.

Fields

• recipients: One or more RecipientInfo entries

  • May contain multiple types of RecipientInfo
  • All entries must indicate/contain the same data encryption key

• ciphertext: Encrypted data

  • Contains encrypted Ieee1609Dot2Data structure (per 5.3.4.2)

Critical Information Fields

The recipients field is critical (per 5.2.6):

• Implementation must support specified number of RecipientInfo entries
• Must support at least eight entries
• Failure to support required number results in decryption failure

Raw Data Example

For plaintext that isn’t from previous SDS operation, it can be encapsulated in Ieee1609Dot2Data of type unsecuredData (per 4.2.2.2.2):

Raw data:    01 23 45 67 89 AB CD EF
COER encoded: 03 80 08 01 23 45 67 89 AB CD EF
Where:
- 03: protocolVersion
- 80: choice unsecuredData
- 08: length of raw data

Fields

recipients: SequenceOfRecipientInfo

ciphertext: SymmetricCiphertext

Implementations

impl EncryptedData

pub fn builder() -> EncryptedDataBuilder

Create an instance of EncryptedData using the builder syntax

Trait Implementations

impl AsnType for EncryptedData

const TAG: Tag = { rasn::types::Tag::SEQUENCE }

The associated tag for the type.

const IDENTIFIER: Identifier

Identifier of an ASN.1 type as specified in the original specification if not identical with the identifier of Self

const TAG_TREE: TagTree = _
