CAMELLIA-CBC buffer encryption/decryption Length should be a multiple of the block size (16 bytes)
- Note
- Upon exit, the content of the IV is updated so that you can call the function same function again on the following block(s) of data and get the same result as if it was encrypted in one call. This allows a "streaming" usage. If on the other hand you need to retain the contents of the IV, you should either save it manually or use the cipher module instead.
- Parameters
-
ctx | CAMELLIA context |
mode | MBEDTLS_CAMELLIA_ENCRYPT or MBEDTLS_CAMELLIA_DECRYPT |
length | length of the input data |
iv | initialization vector (updated after use) |
input | buffer holding the input data |
output | buffer holding the output data |
- Returns
- 0 if successful, or MBEDTLS_ERR_CAMELLIA_INVALID_INPUT_LENGTH

CAMELLIA-CFB128 buffer encryption/decryption.
Note: Due to the nature of CFB you should use the same key schedule for both encryption and decryption. So a context initialized with mbedtls_camellia_setkey_enc() for both MBEDTLS_CAMELLIA_ENCRYPT and CAMELLIE_DECRYPT.

CAMELLIA-CTR buffer encryption/decryption.
Warning: You have to keep the maximum use of your counter in mind!
Note: Due to the nature of CTR you should use the same key schedule for both encryption and decryption. So a context initialized with mbedtls_camellia_setkey_enc() for both MBEDTLS_CAMELLIA_ENCRYPT and MBEDTLS_CAMELLIA_DECRYPT.
- Parameters
-
ctx | CAMELLIA context |
length | The length of the data |
nc_off | The offset in the current stream_block (for resuming within current cipher stream). The offset pointer to should be 0 at the start of a stream. |
nonce_counter | The 128-bit nonce and counter. |
stream_block | The saved stream-block for resuming. Is overwritten by the function. |
input | The input data stream |
output | The output data stream |
- Returns
- 0 if successful
