class _ECDH256: (source)
Implements interfaces: twisted.conch.ssh._kex._IEllipticCurveExchangeKexAlgorithm
Elliptic Curve Key Exchange with SHA-256 as HASH. Defined in RFC 5656.
Note that ecdh-sha2-nistp256 takes priority over nistp384 or nistp512. This is the same priority from OpenSSH.
ecdh-sha2-nistp256 is considered preety good cryptography. If you need something better consider using curve25519-sha256.
| Class Variable | preference |
An int giving the preference of the algorithm when negotiating key exchange. Algorithms with lower precedence values are more preferred. |
