Struct aws_nitro_enclaves_cose::encrypt::CoseEncrypt0

pub struct CoseEncrypt0 { /* private fields */ }

Implementation of the COSE_Encrypt0 structure as defined in RFC8152.

The COSE_Encrypt0 encrypted structure does not have the ability to specify recipients of the message. The structure assumes that the recipient of the object will already know the identity of the key to be used in order to decrypt the message. If a key needs to be identified to the recipient, the enveloped structure ought to be used.

The COSE_Encrypt0 structure can be encoded as either tagged or untagged depending on the context it will be used in. A tagged COSE_Encrypt0 structure is identified by the CBOR tag 16. The CDDL fragment that represents this is:

COSE_Encrypt0_Tagged = #6.16(COSE_Encrypt0)

The COSE_Encrypt0 structure is a CBOR array. The fields of the array in order are:

protected: This is as described in Section 3.

unprotected: This is as described in Section 3.

ciphertext: This is as described in Section 5.1.

The CDDL fragment that represents the above text for COSE_Encrypt0 follows.

COSE_Encrypt0 = [ Headers, ciphertext : bstr / nil, ]

Implementations

impl CoseEncrypt0

pub fn new<C: Encryption + Entropy>( payload: &[u8], cipher_config: CipherConfiguration, key: &[u8] ) -> Result<Self, CoseError>

Creates a new instance of the COSE_Encrypt0 structure and encrypts the provided payload. https://datatracker.ietf.org/doc/html/rfc8152#section-5.3

pub fn decrypt<C: Decryption>( &self, key: &[u8] ) -> Result<(HeaderMap, &HeaderMap, Vec<u8>), CoseError>

Decrypt the ciphertext in the COSE_Encrypt0 structure and returns both the protected and unprotected HeaderMap(s). https://datatracker.ietf.org/doc/html/rfc8152#section-5.3

pub fn as_bytes(&self, tagged: bool) -> Result<Vec<u8>, CoseError>

Serializes the structure for transport / storage. If tagged is true, the optional #6.16 tag is added to the output.

pub fn from_bytes(bytes: &[u8]) -> Result<Self, CoseError>

This function deserializes the structure, but doesn’t check the contents for correctness at all. Accepts untagged structures or structures with tag 16.
