JSch 2.28.0 now supports OpenSSH certificates (PR #901, resolving issue #31).

This includes:

• User certificate authentication — authenticate using OpenSSH certificates signed by a trusted CA instead of plain public keys
• Host certificate verification — verify server identity via CA-signed host certificates instead of relying solely on known_hosts
• CA signature algorithm configuration — control which algorithms are accepted for CA signatures (CASignatureAlgorithms, matching OpenSSH 8.2+ defaults)

Added support for OpenSSH certificate-based authentication and host verification to the camel remote file components that use JSch (sftp, scp).
