Camellia - ECB

Camellia in ECB (Electronic Codebook) mode: each 16-byte block is encrypted or decrypted independently. No IV is used. Same security caveats as AES - ECB—use only for single-block or deterministic single-block use cases; never for bulk data.

API

noxtls_camellia_encrypt_ecb

noxtls_return_t noxtls_camellia_encrypt_ecb(const uint8_t* key, const uint8_t* data, uint32_t data_len, const uint8_t* iv, uint8_t* output, noxtls_camellia_type_t type);

Encrypts data in Camellia ECB mode. IV is not used; may be NULL.

Parameters: key — encryption key; data — plaintext; data_len — length (multiple of 16); iv — unused (NULL); output — ciphertext buffer; type — NOXTLS_CAMELLIA_128_BIT, NOXTLS_CAMELLIA_192_BIT, or NOXTLS_CAMELLIA_256_BIT.

Returns: noxtls_return_t: NOXTLS_RETURN_SUCCESS on success; otherwise a specific return code.

noxtls_camellia_decrypt_ecb

noxtls_return_t noxtls_camellia_decrypt_ecb(const uint8_t* key, const uint8_t* data, uint32_t data_len, const uint8_t* iv, uint8_t* output, noxtls_camellia_type_t type);

Decrypts data in Camellia ECB mode. IV is not used; may be NULL.

Parameters: key — decryption key; data — ciphertext; data_len — length (multiple of 16); iv — unused (NULL); output — plaintext buffer; type — Camellia key type.

Returns: noxtls_return_t: NOXTLS_RETURN_SUCCESS on success; otherwise a specific return code.
