Submit public PGP key

In this example we assume that keyserver public URL is http://spks.example.com and the mail verification is enabled:

1. Create a new keypair with Singularity:

   singularity key newpair --email=user@example.com --name="John Doe" --comment="Signing key" --push=false
   Enter a passphrase: ****
   Retype your passphrase: ****
   Generating Entity and OpenPGP Key Pair... done
   NOT pushing newly created key to: https://keys.sylabs.io
   

2. Retrieve key fingerprint:

   singularity key list
   Public key listing (/home/user/.singularity/sypgp/pgp-public):
   
   0) U: John Doe (Signing key) <user@example.com>

      F: D1B2B32B87D65FB39D2C9908B84B5CE669411080
      L: 4096
      --------
   

3. First push of the key to http://spks.example.com for validation:

   singularity key push -u http://spks.example.com D1B2B32B87D65FB39D2C9908B84B5CE669411080
   

   During this first push, the keyserver send a mail to user@example.com containing the key push command to execute to finalize the key submission.

4. Second push of the key to http://spks.example.com for:

   The server has sent a key push command with a token associated to validate the key submission, the command should be of the form :

   singularity key push -u http://f71dbe52628a3f83a77ab494817525c6@spks.example.com B84B5CE669411080
