fun main() {
CI=Always set to true.
GITHUB_ACTION=The name of the action currently running, or the id of a step. For example, for an action, __repo-owner_name-of-action-repo. GitHub removes special characters, and uses the name __run when the current step runs a script without an id. If you use the same script or action more than once in the same job, the name will include a suffix that consists of the sequence number preceded by an underscore. For example, the first script you run will have the name __run, and the second script will be named __run_2. Similarly, the second invocation of actions/checkout will be actionscheckout2.
GITHUB_ACTION_PATH=The path where an action is located. This property is only supported in composite actions. You can use this path to access files located in the same repository as the action. For example, /home/runner/work/_actions/repo-owner/name-of-action-repo/v1.
GITHUB_ACTION_REPOSITORY=For a step executing an action, this is the owner and repository name of the action. Fo

How to convert a java private key from PKCS#1 encoding to PKCS#8
View convert to pkcs

I had some historical key material data in pkcs#1 format that needed to be in pkcs#8 for input into another system. Here's how to do it, using BouncyCastle:

import org.bouncycastle.asn1.ASN1InputStream;
import org.bouncycastle.asn1.DERObject;
import org.bouncycastle.asn1.pkcs.PKCSObjectIdentifiers;
import org.bouncycastle.asn1.pkcs.PrivateKeyInfo;
import org.bouncycastle.asn1.x509.AlgorithmIdentifier;
