What is the key size range for Twofish encryption?

The key size range for Twofish encryption is indeed from 128 bits to 256 bits. Twofish is a symmetric key block cipher that supports various key sizes, including 128, 192, and 256 bits. This flexibility allows Twofish to provide a good balance between security and performance, making it adaptable for different applications where varying levels of encryption strength might be needed.

By supporting key sizes up to 256 bits, Twofish offers a robust security level that can withstand brute-force attacks, which enhances its utility in cryptographic applications requiring high security. The ability to use 128, 192, or 256 bits gives developers and system architects the choice to tailor their security posture based on their specific needs and threat models.
