#include <cipher.h>
Cipher information. Allows calling cipher functions in a generic way.
- Note
- The library does not support custom cipher info structures, only built-in structures returned by the functions mbedtls_cipher_info_from_string(), mbedtls_cipher_info_from_type(), mbedtls_cipher_info_from_values(), mbedtls_cipher_info_from_psa().
-
Some fields store a value that has been right-shifted to save code-size, so should not be used directly. The accessor functions adjust for this and return the "natural" value.

◆ private_base_idx
unsigned int mbedtls_cipher_info_t::private_base_idx |
Index to LUT for base cipher information and functions.
Definition at line 305 of file cipher.h.
◆ private_block_size
unsigned int mbedtls_cipher_info_t::private_block_size |
The block size, in bytes.
Definition at line 271 of file cipher.h.
◆ private_flags
unsigned int mbedtls_cipher_info_t::private_flags |
Bitflag comprised of MBEDTLS_CIPHER_VARIABLE_IV_LEN and MBEDTLS_CIPHER_VARIABLE_KEY_LEN indicating whether the cipher supports variable IV or variable key sizes, respectively.
Definition at line 302 of file cipher.h.
◆ private_iv_size
unsigned int mbedtls_cipher_info_t::private_iv_size |
IV or nonce size, in bytes (right shifted by MBEDTLS_IV_SIZE_SHIFT). For ciphers that accept variable IV sizes, this is the recommended size.
Definition at line 277 of file cipher.h.
◆ private_key_bitlen
unsigned int mbedtls_cipher_info_t::private_key_bitlen |
The cipher key length, in bits (right shifted by MBEDTLS_KEY_BITLEN_SHIFT). This is the default length for variable sized ciphers. Includes parity bits for ciphers like DES.
Definition at line 283 of file cipher.h.
◆ private_mode
unsigned int mbedtls_cipher_info_t::private_mode |
The cipher mode (as per mbedtls_cipher_mode_t). For example, MBEDTLS_MODE_CBC.
Definition at line 288 of file cipher.h.
◆ private_name
const char* mbedtls_cipher_info_t::private_name |
Name of the cipher.
Definition at line 268 of file cipher.h.
◆ private_type
unsigned int mbedtls_cipher_info_t::private_type |
Full cipher identifier (as per mbedtls_cipher_type_t). For example, MBEDTLS_CIPHER_AES_256_CBC.
This could be 7 bits, but 8 bits retains byte alignment for the next field, which reduces code size to access that field.
