AESContext

    Interface to low level AES encryption features.

    This class provides access to AES encryption/decryption of raw data. Both AES-ECB and AES-CBC mode are supported.

    enum Mode:

    • MODE_ECB_ENCRYPT = 0 —- AES electronic codebook encryption mode.

    • MODE_ECB_DECRYPT = 1 —- AES electronic codebook decryption mode.

    • MODE_MAX = 4 —- Maximum value for the mode enum.

    • void finish ( )

    Close this AES context so it can be started again. See start.

    • get_iv_state ( )

    Get the current IV state for this context (IV gets updated when calling update). You normally don’t need this function.

    Note: This function only makes sense when the context is started with or MODE_CBC_DECRYPT.

    Start the AES context in the given . A key of either 16 or 32 bytes must always be provided, while an (initialization vector) of exactly 16 bytes, is only needed when mode is either or MODE_CBC_DECRYPT.

    Note: The size of src must be a multiple of 16. Apply some padding if needed.
