CAMELLIA-CBC buffer encryption/decryption Length should be a multiple of the block size (16 bytes)
ctx | CAMELLIA context |

length | length of the input data |

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 camellia_setkey_enc() for both CAMELLIA_ENCRYPT and CAMELLIE_DECRYPT.
ctx | CAMELLIA context |
mode | CAMELLIA_ENCRYPT or CAMELLIA_DECRYPT |
length | length of the input data |
iv_off | offset in IV (updated after use) |

output | buffer holding the output data |

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 camellia_setkey_enc() for both CAMELLIA_ENCRYPT and CAMELLIA_DECRYPT.
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 |
