Crytpo operation requires specific input from the user, e.g. the wrapped credential that the
device is configured with. The input should be provided in JSON format in a file in this path:
"/tmp/mlx5_crypto_test.txt".
User can also set this environment variable with his file path: MLX5_CRYPTO_TEST_INFO

This doc describes the input option with examples to the format:
Mandatory:
Wrapped credential: The credential that was configured in the device wrapped.
Wrapped key: Wrapped key for the DEK creation. The key should be encrypted using the KEK
             (Key Encrypted Key).
Optional:
Wrapped 256 bits key: Wrapped key for the DEK creation when the key size of 256 bits is required.
                      If not provided, that test will only use the key in size of 128 bits.
Encrypted data for 512 of 'c': If a user wants to have data validation, he needs to provide
                               expected encrypted data for a plain text of 512 bytes of the
                               character 'c'. If not provided, data validation will be skipped.

Example of content of such file:
