Tiny caveat here is that, as it was before, this command is context dependent. If we execute travis encrypt-file from a different directory, even if the command is invoked on the same file, we will compute a different hash. This is not documented anywhere, but it is worth pointing it out.

@BanzaiMan without having verified it, i believe that input_path is whatever path is passed to travis encrypt path/to/file (i.e. it would be path/to/file). so yes, i guess that counts as context dependent, but it kinda makes sense to me, as such paths would be considered unique per repo, too (and so would the resulting env vars)?

@env_prefix ||= "encrypted_#{Digest.hexencode(Digest::SHA1.digest(input_path)[0..5])}"
"#{@env_prefix}_#{name}"
end
