15 accelerated implementation of the Blake2s library interface,
16 either builtin or as a module.

21 This symbol can be depended upon by arch implementations of the
22 Blake2s library interface that require the generic code as a
23 fallback, e.g., for SIMD implementations. If no arch specific
24 implementation is enabled, this implementation serves the users
25 of CRYPTO_LIB_BLAKE2S.

30 Declares whether the architecture provides an arch-specific
31 accelerated implementation of the ChaCha library interface,

51 by either the generic implementation or an arch-specific one, if one
52 is available and enabled.
