Travis encrypt "data too large" for PyPI tokens with older repos

@hugovk The above means that in the meantime, you can get around the limitation by splitting your secret value into chunks of at most 128 bytes, encrypting them separately, then combining the result back.
You’ll need to make separate secret variables from the results of each encrypt:

$ travis encrypt "SECRET1=foo"    #"SECRET1=foo" (quthout quotes) must be <=128 bytes
<...>
secure: "abcdef...."

$ travis encrypt "SECRET2=bar"
<...>
secure: "ghijkl...."

$ travis encrypt "SECRET3=baz"
<...>
secure: "mnopqr...."

# .travis.yml:

env:
  global:
    - secure: "abcdef...."
    - secure: "ghijkl...."
    - secure: "mnopqr...."
<...>
  #somewhere
  - $SECRET1$SECRET2$SECRET3    #will pass "foobarbaz" (without quotes)
