Hi, We are using JSch 0.1.54 version and is does not support the latest kex algorithms and hence our sftp client is not working. The SFTP server is supporting the following strong algorithms: curve25519-sha256@libssh.org, diffie-hellman-group14-sha256, diffie-hellman-group16-sha512, rsa2048-sha256, diffie-hellman-group18-sha512 JSch supports old algos: ecdh-sha2-nistp256, ecdh-sha2-nistp384, ecdh-sha2-nistp521, diffie-hellman-group14-sha1, diffie-hellman-group-exchange-sha256, diffie-hellman-group-exchange-sha1,...
