Module crypto_op

Structs§

AE: An operation for conducting authenticated encryption / decryption.
Asymmetric: An operation for conducting asymmetric encryption /decryption or asymmetric sign / verify. Note that asymmetric encryption is always “single-stage”, which differs from Cipher which are always “multi-stage”.
Cipher: An operation for conducting symmetric cipher encryption / decryption. This operation defines the way to perform symmetric cipher operations, such as AES. They cover both block ciphers and stream ciphers.
DeriveKey: An operation for derive a shared key object.
Digest: An operation for digest the message.
Mac: An operation for performing MAC (Message Authentication Code) operations, such as HMAC or AES-CMAC operations. This operation is not used for Authenticated Encryption algorithms, which SHALL use the functions defined in AE.
OperationHandle: An opaque reference that identifies a particular cryptographic operation.
OperationInfo: Represent the information about a crypto information.
OperationInfoMultiple: Represent the information about a crypto information which uses multiple keys.
Random: An operation for generating random data.

AlgorithmId: Algorithms that can be allocated as an crypto operation.
ElementId: This specification defines support for optional cryptographic elements.
OperationConstant: Define the supported crypto operation.
OperationMode: Specify one of the available cryptographic operations.
OperationStates: Every operation of AE, Asymmetric, Cipher, DeriveKey, Digest, Mac can be either one of the two states.

is_algorithm_supported: determine whether a combination of algId and element is supported
