Summary

Declaration

typedef struct mbedtls_aes_context { int MBEDTLS_PRIVATE(nr); size_t MBEDTLS_PRIVATE(rk_offset); #if defined(MBEDTLS_AES_ONLY_128_BIT_KEY_LENGTH) && !defined(MBEDTLS_PADLOCK_C) uint32_t MBEDTLS_PRIVATE(buf)[44]; #else uint32_t MBEDTLS_PRIVATE(buf)[68]; #endif } mbedtls_aes_context;

Description

private_nr

int MBEDTLS_PRIVATE

private_rk_offset

size_t MBEDTLS_PRIVATE

private_buf

uint32_t MBEDTLS_PRIVATE(buf)[68]

Unaligned data buffer. This buffer can hold 32 extra Bytes, which can be used for one of the following purposes: Alignment if VIA padlock is used. Simplifying key expansion in the 256-bit case by generating an extra round key.

mbedtls_aes_context::nr

int MBEDTLS_PRIVATE(nr

mbedtls_aes_context::rk_offset

size_t MBEDTLS_PRIVATE(rk_offset

mbedtls_aes_context::buf

uint32_t MBEDTLS_PRIVATE(buf)[68]

Unaligned data buffer. This buffer can hold 32 extra Bytes, which can be used for one of the following purposes: Alignment if VIA padlock is used. Simplifying key expansion in the 256-bit case by generating an extra round key.
