- moloch-hai 4y agoZbc (carryless multiply) seems to be needed to implement AES-GCM
- snvzz 4y agoIt is required in Zkn (Scalar Crypto NIST Algorithms) and Zks (Scalar Crypto ShangMi Algorithms).
- gary_0 4y agoAh, you're right: https://github.com/riscv/riscv-profiles/blob/main/profiles.adoc#rva22-profiles https://github.com/riscv/riscv-profiles/blob/main/profiles.a... That's good to see. (Boy, it's really hard to find info about RISC-V profiles on Google. It just seems to ignore all the letters and numbers.)
