I'll check out salsa20. This is for a design project and the reason I picked Simon/Speck is because that's the algorithm that my professor approved. But as I'm working on this, I've been gaining much more of an appreciation for encryption, so I appreciate the recommendation! WebAug 8, 2024 · A bit of history. Speck was merged for the 4.17 kernel and the fscrypt module for ext4 and F2FS added Speck128 and Speck256 support in 4.18. Speck is a block cipher, rather than a stream cipher, which makes it suitable for uses like filesystem encryption. As Eric Biggers noted when Speck was proposed in February, it is a good choice for low-end ... hotels in carlisle pa with indoor pool
