I'm running a github workflow I've used many times in the past to publish code to nexus. It is failing now. I haven't used it in a while, so it's possible my original key expired...been >3 yrs since I created it and I can't remember if I set it to expire or not.
I generated a new rsa key with gpg and default length (about 3K I think), published it to keyserver.ubuntu.com, and pasted it into my secret variable PGP_SECRET in my project's github repo, which my gpg command uses.
I run my workflow with the gpg command in it, and get this error:
Running ci-release.
branch=refs/tags/v1.2.2
gpg (GnuPG) 2.2.27
java.lang.RuntimeException: base64: invalid input
...
[error] base64: invalid input
[error] Use 'last' for the full log.
Error: Process completed with exit code 1.
What is this error, and how can I fix it? Does this mean my RSA key is bad/unrecognized by github?
(I'll add that I can successfully encrypt/decript with my key locally using gpg.)
Found out the missing piece--need to convert to base64.
Steps:
1. gpg --full-generate-key (answer all promopts--remember passphrase)
-> Choose RSA, default length
2. gpg --keyserver keyserver.ubuntu.com --send-keys <key_id> (publish key to the world)
3. gpg --armor --export-secret-keys <key_id> | base64
4. cut/paste this ascii block into wherever it will be use, e.g. github secret var
