Module optee_utee::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.

Enums

• 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.

Traits

• OpHandle
  A trait for a crypto operation to return its handle.

Functions

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