travis encrypt-file for maven deploy - travis-ci

Question

On my computer:
travis login --org
Username: xxxxxx
Password: xxxxxx
Successfully logged in as xxxxxx!
travis encrypt-file codesigning.asc -r XXXXXX/XXXXXX
encrypting codesigning.asc for XXXXXX/XXXXXX
storing result as codesigning.asc.enc
storing secure env variables for decryption
Please add the following to your build script (before_install stage in your .travis.yml, for instance):
openssl aes-256-cbc -K $encrypted_abcd1234_key -iv $encrypted_abcd1234_iv -in codesigning.asc.enc -out codesigning.asc -d
Pro Tip: You can add it automatically by running with --add.
Make sure to add codesigning.asc.enc to the git repository.
Make sure not to add codesigning.asc to the git repository.
Commit all changes to your .travis.yml.
On my travis acount:
On my GitHub repository:
I paste the codesigning.asc.enc file in the test folder test/codesigning.asc.enc.
I add this shell script:
if [ "$TRAVIS_BRANCH" = 'master' ] && [ "$TRAVIS_PULL_REQUEST" == 'false' ]; then
echo "******** Starting gpg"
openssl aes-256-cbc -K "$encrypted_abcd1234_key" -iv "$encrypted_abcd1234_iv" -in test/codesigning.asc.enc -out test/codesigning.asc -d
gpg --fast-import test/codesigning.asc
fi
I have this error on my travis console:
bad decrypt
139864985556640:error:06065064:digital envelope routines:EVP_DecryptFinal_ex:bad decrypt:evp_enc.c:539:

Answer 1

OpenPGP (the cryptographic protocol implemented by gpg) and X.509 (the cryptographic protocol used by OpenSSL) are not compatible. You cannot import this key to GnuPG (you could to gpgsm which implements X.509, but this is not the normal gpg you want to use). You will have to stick with OpenSSL or GnuTLS to handle the key and encrypted messages for it.
