Generic cipher context.

Fields

cipher_info: *const mbedtls_cipher_info_t

Information about the associated cipher

key_bitlen: c_int

Key length to use

operation: mbedtls_operation_t

Operation that the context’s key has been initialised for

add_padding: Option<unsafe extern "C" fn(output: *mut c_uchar, olen: usize, data_len: usize)>

Padding functions to use, if relevant for cipher mode

get_padding: Option<unsafe extern "C" fn(input: *mut c_uchar, ilen: usize, data_len: *mut usize) -> c_int>

unprocessed_data: [c_uchar; 16]

Buffer for data that hasn’t been encrypted yet

unprocessed_len: usize

Number of bytes that still need processing

iv: [c_uchar; 16]

Current IV or NONCE_COUNTER for CTR-mode

iv_size: usize

IV size in bytes (for ciphers with variable-length IVs)
