Yup, 128 and 256, that's correct!

Wait, is it really 256 bits? I thought it was less.

256-bit blocks and 256-bit keys. Ah, the good old days when we used to encrypt our messages with a pen and paper.

256-bit blocks and 512-bit keys. Wow, that's a lot of bits! My calculator can't even handle that many.

I definitely recall that Twofish uses 128-bit blocks, but the maximum key length is tricky. I think it’s 256 bits, but I could be wrong.

I might be mixing it up, but I feel like Twofish has a block size of 128 bits. The key length... maybe it goes up to 192 bits?

I remember practicing with symmetric algorithms, and I believe Twofish uses 128-bit blocks and can support up to 256 bits for the key length.

I think Twofish operates on 128-bit blocks, but I'm not entirely sure about the key length. Was it 256 bits?

Okay, I think I've got it. Twofish operates on 128-bit blocks and can support key lengths up to 256 bits. I'll write that down and double-check before submitting.

Wait, was it 128-bit blocks or 256-bit blocks? And the key length, was that 128 bits or 256 bits? Hmm, I'm getting a bit mixed up here. Let me review my notes quickly.

I've got this! Twofish is a 128-bit block cipher that can use keys up to 256 bits long. I'm confident I can fill in those blanks correctly.

Okay, Twofish is a symmetric algorithm, so it operates on fixed-size blocks. I'm pretty sure the block size is 128 bits, but I'll have to double-check that. As for the key length, I believe it can support up to 256 bits, but I'm not 100% certain.

Hmm, I think I remember learning about Twofish in my cryptography class, but I'm a bit fuzzy on the details. Let me think this through step-by-step.
