2.5 Camellia Algorithm

Camellia was developed jointly by NTT and Mitsubishi Electric Corporation in the year 2000. Camellia is a symmetric cipher with a Feistel structure. The cipher was named for the flower Camellia japonica, which is known for being long-lived as well as because the cipher was developed in Japan.

Camellia is one of the three ISO/IEC international standard 128-bit block ciphers (Camellia, AES, and SEED). Camellia was selected as a recommended cryptographic primitive by the EU NESSIE project and was included in the list of cryptographic techniques for Japanese e-Government systems that was selected by the Japanese CRYPTREC.

This API supports only the ECB and CBC modes of operation for the Camellia algorithm.
