Codespaces user secrets

The Codespaces user secrets API allows a user to create, list, and delete secrets (such as access tokens for cloud services) as well as assign secrets to repositories that the user has access to in a codespace.

About the Codespaces user secrets API

The Codespaces user secrets API allows a user to create, list, and delete secrets (such as access tokens for cloud services) as well as assign secrets to repositories that the user has access to. Estos secretos se hacen disponibles para el codespace en el tiempo de ejecución. Para obtener más información, consulta la sección "Administrar los secretos cifrados para tu codespace".

Create or update a secret for the authenticated user

Creates or updates a secret for a user's codespace with an encrypted value. Encrypt your secret using LibSodium.

You must authenticate using an access token with the codespace or codespace:secrets scope to use this endpoint. User must also have Codespaces access to use this endpoint.

GitHub Apps must have read access to the codespaces_user_secrets user permission and codespaces_secrets repository permission on all referenced repositories to use this endpoint.

Example encrypting a secret using Node.js

Encrypt your secret using the tweetsodium library.

const sodium = require('tweetsodium');

const key = "base64-encoded-public-key";
const value = "plain-text-secret";

// Convert the message and key to Uint8Array's (Buffer implements that interface)
const messageBytes = Buffer.from(value);
const keyBytes = Buffer.from(key, 'base64');

// Encrypt using LibSodium.
const encryptedBytes = sodium.seal(messageBytes, keyBytes);

// Base64 the encrypted secret
const encrypted = Buffer.from(encryptedBytes).toString('base64');

console.log(encrypted);

Example encrypting a secret using Python

Encrypt your secret using pynacl with Python 3.

from base64 import b64encode
from nacl import encoding, public

def encrypt(public_key: str, secret_value: str) -> str:
  """Encrypt a Unicode string using the public key."""
  public_key = public.PublicKey(public_key.encode("utf-8"), encoding.Base64Encoder())
  sealed_box = public.SealedBox(public_key)
  encrypted = sealed_box.encrypt(secret_value.encode("utf-8"))
  return b64encode(encrypted).decode("utf-8")

Example encrypting a secret using C#

Encrypt your secret using the Sodium.Core package.

var secretValue = System.Text.Encoding.UTF8.GetBytes("mySecret");
var publicKey = Convert.FromBase64String("2Sg8iYjAxxmI2LvUXpJjkYrMxURPc8r+dB7TJyvvcCU=");

var sealedPublicKeyBox = Sodium.SealedPublicKeyBox.Create(secretValue, publicKey);

Console.WriteLine(Convert.ToBase64String(sealedPublicKeyBox));

Example encrypting a secret using Ruby

Encrypt your secret using the rbnacl gem.

require "rbnacl"
require "base64"

key = Base64.decode64("+ZYvJDZMHUfBkJdyq5Zm9SKqeuBQ4sj+6sfjlH4CgG0=")
public_key = RbNaCl::PublicKey.new(key)

box = RbNaCl::Boxes::Sealed.from_public_key(public_key)
encrypted_secret = box.encrypt("my_secret")

# Print the base64 encoded secret
puts Base64.strict_encode64(encrypted_secret)
