Struct containing the parameters required for encrypting/decrypting and authenticating/verifying a message for one-step operations.
§ key
§ aad
| uint8_t* AESGCM_OneStepOperation::aad |
A buffer of length aadLength containing additional authentication data to be authenticated/verified but not encrypted/decrypted.
§ input
| uint8_t* AESGCM_OneStepOperation::input |
- Encryption: The plaintext buffer to be encrypted and authenticated in the GCM operation.
- Decryption: The ciphertext to be decrypted and verified.
§ output
| uint8_t* AESGCM_OneStepOperation::output |
- Encryption: The output ciphertext buffer that the encrypted plaintext is copied to.
- Decryption: The plaintext derived from the decrypted and verified ciphertext is copied here.
§ iv
| uint8_t* AESGCM_OneStepOperation::iv |
A buffer containing an IV. IVs must be unique to each GCM operation and may not be reused. If ivInternallyGenerated is set, the IV will be generated by AESGCM_oneStepEncrypt() and copied to this buffer.
§ mac
| uint8_t* AESGCM_OneStepOperation::mac |
- Encryption: The buffer where the message authentication code is copied.
- Decryption: The buffer containing the received message authentication code.
§ aadLength
| size_t AESGCM_OneStepOperation::aadLength |
Length of the total aad in bytes. Either aadLength or inputLength must be non-zero.
§ inputLength
| size_t AESGCM_OneStepOperation::inputLength |
Length of the input/output data in bytes. Either aadLength or inputLength must be non-zero. Unlike this field in AESGCM_SegmentedDataOperation, the length doesn't need to be block-aligned.
§ ivLength
| uint8_t AESGCM_OneStepOperation::ivLength |
Length of IV in bytes. See implementation-specific header for IV length support.
§ macLength
| uint8_t AESGCM_OneStepOperation::macLength |
Length of mac in bytes. Valid MAC lengths are [4, 8, 12, 13, 14, 15, 16].
§ ivInternallyGenerated
| bool AESGCM_OneStepOperation::ivInternallyGenerated |
When true, the IV buffer passed into AESGCM_oneStepEncrypt() will be overwritten with a randomly generated IV. Not supported by all implementations.
