Comment (by sysrqb):

 I created a short-term keypair for only the initial alpha releases. We
 will create a new, long-term key before the first stable release. I have
 this key offline.

 {{{
 $ keytool -genkey -v -keystore tba_alpha.p12 -storetype pkcs12 -keyalg RSA
 -keysize 3072 -validity 10000 -alias tba_alpha
 }}}

 I debated whether we should create the key using RSA or ECDSA. I decided
 on using RSA, but we can discuss this later, before creating the long-term
 key.
