Using PGP/GPG keys

Widevine requires every device manufacturer to supply a single public PGP/GPG key to be used to secure keybox transfers.

  1. Only one PGP key is allowed per organization (company).
    • The email associated with this PGP key must be from a company email address.
    • Widevine will set up this user-provided PGP key during the first time registration of an organization (company).
  2. All users from the same organization need access to use this PGP key.
  3. Every user must have the private PGP key and passphrase.

Given the above requirements, our recommendations are:

  • To create a group company email address for all users.
  • Generate a PGP key pair using the group email address.
    • Share the PGP key pair information among all company users.
  • Provide this public PGP key to Widevine.

An example shared company email address = widevine-keys@mycompany.com

Requirements

Use the most recent version of GPG at https://gnupg.org/ for generating the PGP key pair.

To create a PGP keypair using the GPG tools, run:

gpg --gen-key

Please choose option 1 - RSA and RSA. Our system ONLY supports RSA.

Please select what kind of key you want:
   (1) RSA and RSA (default)
   (2) DSA and Elgamal
   (3) DSA (sign only)
   (4) RSA (sign only)
Your selection? 1
RSA keys may be between 1024 and 8192 bits long.
What keysize do you want? (2048)
Requested keysize is 2048 bits
Please specify how long the key should be valid.
         0 = key does not expire
      <n>  = key expires in n days
      <n>w = key expires in n weeks
      <n>m = key expires in n months
      <n>y = key expires in n years
Key is valid for? (0)
Key does not expire at all
Is this correct? (y/N) y

Once you have created your PGP/GPG keys, please export just the PUBLIC key in ASCII Armor format (please do not send us your secret key).

gpg --armor --export email@domain.com

Again, this email address needs to be your shared company email address and not your individual company email address.
