Generic cipher context.

Fields

private_cipher_info: *const mbedtls_cipher_info_t

Information about the associated cipher.

private_key_bitlen: c_int

Key length to use.

private_operation: mbedtls_operation_t

Operation that the key of the context has been initialized for.

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

Padding functions to use, if relevant for the specific cipher mode.

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

private_unprocessed_data: [c_uchar; 16]

Buffer for input that has not been processed yet.

private_unprocessed_len: usize

Number of Bytes that have not been processed yet.

private_iv: [c_uchar; 16]

Current IV or NONCE_COUNTER for CTR-mode, data unit (or sector) number for XTS-mode.

private_iv_size: usize

IV size in Bytes, for ciphers with variable-length IVs.

private_cipher_ctx: *mut c_void

The cipher-specific context.

private_cmac_ctx: *mut mbedtls_cmac_context_t

CMAC-specific context.
