=> https://ntruprime.cr.yp.to/ Streamlined NTRU Prime KEM algorithm
=> https://datatracker.ietf.org/doc/html/rfc7748.html X25519

Combined Streamlined NTRU Prime 761 and X25519 public keys are
used for KEM purposes, so should have "kem" key usage set.

Its algorithm identifier is "sntrup761-x25519".
Its public key value is a concatenation of 1158-byte
SNTRUP761 public key and 32-byte X25519 one.

Public key's fingerprint should be calculated using BLAKE2b hash
with 256 bit output length specified.
