/**
 * Secret key of type {@link PublicKeyAlgorithmTags#X25519}.
 * This type was introduced with RFC9580 and can be used with v4, v6 keys.
 * Note however, that legacy implementations might not understand this key type yet.
 * For a key type compatible with legacy v4 implementations, see {@link ECSecretBCPGKey} with
 * {@link PublicKeyAlgorithmTags#ECDH}.
 * Note: Contrary to {@link ECSecretBCPGKey} using {@link PublicKeyAlgorithmTags#ECDH}, which uses big-endian
 * MPI encoding to encode the secret key material, {@link X25519SecretBCPGKey} uses native little-endian encoding.
 *

 *     OpenPGP - Algorithm-Specific Part for X25519 Keys
