Function encode_seed 

pub fn encode_seed(entropy: &Entropy, algorithm: &Algorithm) -> String

Encode the given entropy as an XRP Ledger seed (secret)

The entropy must be exactly 16 bytes (128 bits). The encoding includes which elliptic curve digital signature algorithm the seed is intended to be used with. The seed is used to produce the private key.

Examples

use ripple_address_codec::{encode_seed, Secp256k1, Ed25519};

// In the real world you **must** generate random entropy
let naive_entropy = [0; 16];

assert_eq!(encode_seed(&naive_entropy, &Secp256k1), "sp6JS7f14BuwFY8Mw6bTtLKWauoUs");
assert_eq!(encode_seed(&naive_entropy, &Ed25519), "sEdSJHS4oiAdz7w2X2ni1gFiqtbJHqE");
