A social media company wants to change encryption ciphers after identifying weaknesses in the implementation of the existing ciphers. The company needs the new ciphers to meet the following requiremen

IDEA-CBC is an older block cipher that is less efficient and not considered as secure or widely recommended as modern ciphers like ChaCha20-Poly1305 or AES-GCM, and does not specifically meet the TLS 1.3 requirement for optimal performance.

While AES-GCM is a strong and widely used authenticated encryption cipher for TLS 1.3, ChaCha20-Poly1305 often provides better performance on software-only implementations, which is beneficial for minimizing CPU and RAM usage, especially on diverse client devices.

ChaCha20-Poly1305 is a stream cipher that offers excellent performance on a wide range of CPUs, including those without AES-NI, making it very CPU and RAM efficient, and it is a standard authenticated encryption cipher suite supported by TLS 1.3.

Camellia-CBC is a block cipher similar to AES but less widely adopted, and its CBC mode is generally less efficient and secure than authenticated encryption modes, not specifically meeting the high-efficiency and TLS 1.3 requirements for modern applications.
