2022-11-25crypto: arm/nhpoly1305 - eliminate unnecessary CFI wrapperEric Biggers1-1/+1
The arm architecture doesn't support CFI yet, and even if it did, the new CFI implementation supports indirect calls to assembly functions. Therefore, there's no need to use a wrapper function for nh_neon().

2018-11-20crypto: arm/nhpoly1305 - add NEON-accelerated NHPoly1305Eric Biggers1-0/+116
Add an ARM NEON implementation of NHPoly1305, an ε-almost-∆-universal hash function used in the Adiantum encryption mode. For now, only the NH portion is actually NEON-accelerated; the Poly1305 part is less performance-critical so is just implemented in C.
