Keypair derivation from secret key works wrong

[pavlovdog]

Here's the sample code

  const secret = '59ad891197c4eee4ecf156470ecfd2ab42abc89e069f243874a88bcf74f002cb';
  const keyPair = await client.crypto.nacl_sign_keypair_from_secret_key({
    secret
  });
  
  console.log(keyPair);

The keypair in the output is wrong. Looks like the secret is actual secret concatenated with public:

{
  public: '88674ff490dab330f2dc1b09374bdf4e4366e707a78db810ac741383be35616e',
  secret: '59ad891197c4eee4ecf156470ecfd2ab42abc89e069f243874a88bcf74f002cb88674ff490dab330f2dc1b09374bdf4e4366e707a78db810ac741383be35616e'
}

This is by design. See also: https://crypto.stackexchange.com/questions/54353/why-are-nacl-secret-keys-64-bytes-for-signing-but-32-bytes-for-box
