iv undefined error (with fix)

[mvsrgc]

The document at: https://github.com/dwyl/learn-travis/blob/master/encrypted-ssh-keys-deployment.md#5-encrypt-the-private-key

Does not indicate that you have to add the --pro option to travis encrypt-file. If you don't specify --pro, you will get "iv undefined" error during your build.

@eacdev thanks for opening this issue. 👍
This must have changed since we wrote the guide last year.
