 779 automatic generation of random nonces and IVs, simplified CTR cipher mode, and
 780 more)
 781 @item SHA-3 (including SHAKE XOFs) and BLAKE2 hash algorithms

 783 @item scrypt and HKDF
 784 @item Deterministic (EC)DSA
 785 @item Password-protected PKCS#8 key containers
 786 @item Shamir’s Secret Sharing scheme
 787 @item Random numbers get sourced directly from the OS (and not from a CSPRNG
