Codespaces repository secrets

Lists all secrets available in a repository without revealing their encrypted values. You must authenticate using an access token with the repo scope to use this endpoint. GitHub Apps must have the codespaces_secrets repository permission to use this endpoint.

Gets your public key, which you need to encrypt secrets. You need to encrypt a secret before you can create or update secrets. Anyone with read access to the repository can use this endpoint. If the repository is private you must use an access token with the repo scope. GitHub Apps must have the codespaces_secrets repository permission to use this endpoint.

Gets a single repository secret without revealing its encrypted value. You must authenticate using an access token with the repo scope to use this endpoint. GitHub Apps must have the codespaces_secrets repository permission to use this endpoint.

Creates or updates a repository secret with an encrypted value. Encrypt your secret using LibSodium. You must authenticate using an access token with the repo scope to use this endpoint. GitHub Apps must have the codespaces_secrets repository permission to use this endpoint.

Example of 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 of 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 of 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 of 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)

Deletes a secret in a repository using the secret name. You must authenticate using an access token with the repo scope to use this endpoint. GitHub Apps must have the codespaces_secrets repository permission to use this endpoint.
