SHA-256 with its own compression, and on it HMAC-SHA256 with the inner and
outer states of the key computed once, HKDF-SHA256 and PBKDF2-HMAC-SHA256,
whose iterations are two compressions over words; scrypt with Salsa20/8;
ChaCha20, Poly1305 in 13-bit limbs and ChaCha20-Poly1305 with the tag
compared in constant time; X25519 on the field of TweetNaCl in doubles,
with the all-zero secret refused; the strict Ed25519 verification of
internal/ed25519strict; Go's Base64 with the offsets of its errors, and
age's Bech32.
tool/gen_primitive_vectors.go computes every expected value with Go and
x/crypto, from the inputs of RFC 5869, 7748, 7914, 8032 and 8439, edge
cases and seeded random ones. The tests also run compiled to JavaScript,
from a Dart copy of the JSON, without the cases that would take too long.
