CpabeCli.jar keygen causing javax.crypto.BadPaddingException in cpabe-server

overview

The failing job and commit linked bellow demonstrates that the custom randomly generated keys created with CpabeCli.jar are causing test_003_cpabe_server to fail on this test: test_003_download_and_decrypt_sse_keys:

Job #9021 failed for 74a7d00b:

A hotfix has been implemented to re-implement fixtures, see this job and commit

Job #9023 passed for 0b7c79c4:

But it is obviously a security issue so should be addressed as soon as possible

more details

Inspecting the output of the cpabe-server (with docker logs cpabe-server on the cloud node) revealed the following error :

javax.crypto.BadPaddingException: Given final block not properly padded. Such issues can arise if a bad key is used during decryption.

(full traceback attached here: cpabe-server.error.log)

tasks

• determine source of padding error
• implement fix
• deploy and ensure e2e tests are passing
