The encrypt-file command will encrypt an entire file using symmetric (AES-256) encryption and stores the secret in a file. Let us create a file called secret.txt and add the following entries into it: SECRET_VALUE=ABCDE12345 CLIENT_ID=rocky123 CLIENT_SECRET=abc222222!
travis encrypt-file secret.txt -> give this command after creating secret.txt file and it will store result as secret.txt.enc and also shows ->add the following to your build script (before_install stage in your .travis.yml , for instance): - openssl aes-256-cbc -K $encrypted_74945c17fbe2_key -iv $encrypted_74945c17fbe2_iv -in secret.txt.enc -out secret.txt -d
Now add this entry into our .travis.yml script: ( before_install: - openssl aes-256-cbc -K $encrypted_74945c17fbe2_key -iv $encrypted_74945c17fbe2_iv -in secret.txt.enc -out secret.txt -d ) , It can then decrypt values in the secret text file for us
So it is to create a file and use command travis encrypt-file secret.txt, it will then produces an entry, copy that entry and add it into our .travis.yml file in before_install stage
make sure to add the secret.txt.enc to the git repository and make sure NOT to add the secret.txt to the git repository
