What key sizes are available for the Camellia encryption algorithm?

The Camellia encryption algorithm offers key sizes of 128, 192, or 256 bits. This range provides a balance of security and performance, enabling secure encryption for various applications. The three key sizes allow users to select a level of security that meets their specific needs while ensuring compatibility with different security standards.

Choosing 128 bits is generally sufficient for many applications, while 192 and 256 bits offer higher levels of security for sensitive data or longer-term protection. This flexibility is advantageous in a world where security necessities can vary based on the context in which the encryption is applied.

Other options do not accurately reflect the key sizes associated with Camellia. For instance, 64 or 128 bits do not encompass the full range of options offered by Camellia, and neither do the smaller range or broader spectrum of bits listed in the other options. Thus, the key sizes available for Camellia are specifically aligned with the correct answer—128, 192, or 256 bits.
