     Edit this ticket and set Status to Open.`

2. DNS Referencing
   • Go to DNS Manager
   • Add new record below: Type: TXT | Host: @ | TXT Value: [your ticket reference in Sonatype Jira] | TTL: [1 Hour or Auto]
   • E.g: Type: TXT | Host: @ | TXT Value: OSSRH-96022 | TTL: Auto (Config on cloudflare)
   • Test: host -t txt alphalabs.vn
3. Create account or login Sonatype OSS Index at: https://ossindex.sonatype.org/
4. After login Sonatype OSS Index success, login to Nexus UI at: https://s01.oss.sonatype.org/
5. You can upload aar at https://s01.oss.sonatype.org/index.html#staging-upload if have pom file and signature library
6. If not, config library like this demo
7. Generating a GPG Key for
   • Download GPG command line tools from https://www.gnupg.org/download/ and install them.
   • Open your Terminal.
   • Type gpg --full-generate-key
   • When asked what kind of key you want, press Enter to select the default RSA and RSA.
   • When asked about the keysize, type 4096.
   • When asked about the duration of key to be valid, press Enter to select the default, indicating that the key doesn’t expire.
   • When asked about the information for creating a new user ID, provide your name and email address.
   • Enter ‘O’ for Okay.
   • When prompted, create a passphrase to protect your key.
   • This creates your key in ~/.gnupg/openpgp-revocs.d/ with .rev format. Since we need our key in .gpg format, here’s how to create that:
     • In your Terminal, type gpg --export-secret-keys -o secring.gpg .
     • When prompted with the passphrase, type the passphrase you set for the key you created.
   • This should create a file named secring.gpg in your root directory.
