computeExchangeHashGroup14

ubyte[32] computeExchangeHashGroup14(
       scope  const  SshExchangeTranscript transcript)

Computes the exchange hash for diffie-hellman-group14-sha256.

Differs from the curve25519 transcript only in the public-value encodings: e, f, and K enter as canonical mpints (RFC 4253 section 8) instead of length-prefixed raw strings. The shared secret still enters through sharedSecretEncoded, whose mpint form matches DH usage.

Parameters

transcript All exchange-hash inputs; clientPublic and serverPublic hold the raw big-endian magnitudes of e and f, and sharedSecret holds the raw big-endian magnitude of K.

Returns

The 32-byte SHA-256 exchange hash H.
