Struct Ed25519PrivateKey 

pub struct Ed25519PrivateKey(/* private fields */);

An Ed25519 private key for creating digital signatures.

Ed25519 is a public-key signature system based on the Edwards curve over the finite field GF(2^255 - 19). It provides the following features:

• Fast single-signature verification
• Fast key generation
• High security level (equivalent to 128 bits of symmetric security)
• Collision resilience - hash function collisions don’t break security
• Protection against side-channel attacks
• Small signatures (64 bytes) and small keys (32 bytes)

This implementation allows:

• Creating random Ed25519 private keys
• Deriving the corresponding public key
• Signing messages
• Converting between various formats
