Thank you for quick reply.
This test code works .
But if i add
config.put("mac.c2s", "hmac-sha2-256");
session.setConfig(config);
before session.connect(); .
I get com.jcraft.jsch.JSchException: Algorithm negotiation fail
I want to specifically use only hmac-sha2-256 and hmac-sha2-512.
Thanks and Regards,
Usha

|We found that jsch-0.1.49 supports both these algorithms.
|I have implemented the code to have
|config.put("cipher.c2s", "3des-cbc,aes192-cbc,aes128-cbc,aes256-cbc");
|config.put("mac.c2s", "hmac-sha2-256");
|session.setConfig(config);
|session.connect();
|Some how It does not work with the SFTP server which supports this
algo.
|and gives error.
|com.jcraft.jsch.JSchException: Algorithm negotiation fail

Try the following sample program,

You may find the reason for that problem in its outputs.
