--------------------------------------------
Summary: Upgrade SSHJ Library to Support Modern RSA Key Algorithms
Key: AIRAVATA-3918
URL: https://issues.apache.org/jira/browse/AIRAVATA-3918
Project: Airavata
Issue Type: Improvement
Components: Airavata API
Affects Versions: 0.21
Reporter: Lahiru Jayathilake
The current implementation utilizes SSHJ version 0.29.0, which lacks support
for modern RSA key algorithms such as rsa-sha2-256 and rsa-sha2-512. This
limitation leads to authentication failures when connecting to servers that
require these algorithms. Upgrading to SSHJ version 0.39.0 resolves this issue
by providing the necessary support for these algorithms.
