Description

Body

As seen from: https://github.com/apache/airflow/pull/54078, which is a short term fix to workaround DSSKey

  1. Remove DSSKey references entirely in the codebase
  2. Bump minimum to paramiko 4.0+
  3. Provide migration guide for users with DSA keys
  4. Bump types-paramiko version that was limited in https://github.com/apache/airflow/pull/54173

Migration that could be required:

Users would need to: Generate other keys to be used in their connections (RSA, ECDSA, or Ed25519 keys) and update their Airflow connections to use those

Committer

  • I acknowledge that I am a maintainer/committer of the Apache Airflow project.
