Functions |
const int * | mbedtls_cipher_list (void) |
| This function retrieves the list of ciphers supported by the generic cipher module.
|
const mbedtls_cipher_info_t * | mbedtls_cipher_info_from_string (const char *cipher_name) |
| This function retrieves the cipher-information structure associated with the given cipher name.
|
const mbedtls_cipher_info_t * | mbedtls_cipher_info_from_type (const mbedtls_cipher_type_t cipher_type) |
| This function retrieves the cipher-information structure associated with the given cipher type.
|
const mbedtls_cipher_info_t * | mbedtls_cipher_info_from_values (const mbedtls_cipher_id_t cipher_id, int key_bitlen, const mbedtls_cipher_mode_t mode) |
| This function retrieves the cipher-information structure associated with the given cipher ID, key size and mode.
|
void | mbedtls_cipher_init (mbedtls_cipher_context_t *ctx) |
| This function initializes a cipher_context as NONE.
|
void | mbedtls_cipher_free (mbedtls_cipher_context_t *ctx) |
| This function frees and clears the cipher-specific context of ctx . Freeing ctx itself remains the responsibility of the caller.
|
int | mbedtls_cipher_setup (mbedtls_cipher_context_t *ctx, const mbedtls_cipher_info_t *cipher_info) |
| This function initializes and fills the cipher-context structure with the appropriate values. It also clears the structure.
|
static unsigned int | mbedtls_cipher_get_block_size (const mbedtls_cipher_context_t *ctx) |
| This function returns the block size of the given cipher.
|
static mbedtls_cipher_mode_t | mbedtls_cipher_get_cipher_mode (const mbedtls_cipher_context_t *ctx) |
| This function returns the mode of operation for the cipher. For example, MBEDTLS_MODE_CBC.
|
static int | mbedtls_cipher_get_iv_size (const mbedtls_cipher_context_t *ctx) |
| This function returns the size of the IV or nonce of the cipher, in Bytes.
|
static mbedtls_cipher_type_t | mbedtls_cipher_get_type (const mbedtls_cipher_context_t *ctx) |
| This function returns the type of the given cipher.
|
static const char * | mbedtls_cipher_get_name (const mbedtls_cipher_context_t *ctx) |
| This function returns the name of the given cipher as a string.
|
static int | mbedtls_cipher_get_key_bitlen (const mbedtls_cipher_context_t *ctx) |
| This function returns the key length of the cipher.
|
static mbedtls_operation_t | mbedtls_cipher_get_operation (const mbedtls_cipher_context_t *ctx) |
| This function returns the operation of the given cipher.
|
int | mbedtls_cipher_setkey (mbedtls_cipher_context_t *ctx, const unsigned char *key, int key_bitlen, const mbedtls_operation_t operation) |
| This function sets the key to use with the given context.
|
int | mbedtls_cipher_set_iv (mbedtls_cipher_context_t *ctx, const unsigned char *iv, size_t iv_len) |
| This function sets the initialization vector (IV) or nonce.
|
int | mbedtls_cipher_reset (mbedtls_cipher_context_t *ctx) |
| This function resets the cipher state.
|
int | mbedtls_cipher_update (mbedtls_cipher_context_t *ctx, const unsigned char *input, size_t ilen, unsigned char *output, size_t *olen) |
| The generic cipher update function. It encrypts or decrypts using the given cipher context. Writes as many block-sized blocks of data as possible to output. Any data that cannot be written immediately is either added to the next block, or flushed when mbedtls_cipher_finish() is called. Exception: For MBEDTLS_MODE_ECB, expects a single block in size. For example, 16 Bytes for AES.
|
int | mbedtls_cipher_finish (mbedtls_cipher_context_t *ctx, unsigned char *output, size_t *olen) |
| The generic cipher finalization function. If data still needs to be flushed from an incomplete block, the data contained in it is padded to the size of the last block, and written to the output buffer.
|
int | mbedtls_cipher_crypt (mbedtls_cipher_context_t *ctx, const unsigned char *iv, size_t iv_len, const unsigned char *input, size_t ilen, unsigned char *output, size_t *olen) |
| The generic all-in-one encryption/decryption function, for all ciphers except AEAD constructs.
|
The generic cipher wrapper.
