Hello ,

When I am sending unencrypted data its woking fine for me . I am using below commands to send unencrypted data.
UFTP: uftp -Y none -h sha1 -r 0.5:0.5:0.5 -t 20 -s 10 -M 230.4.4.1 -P 230.5.5.1 -p 32322 D:\FTPServer\automationbuild\options-350-19-01B_7830_7835none.dat
UFTPD: "/usr/bin/uftpd", "uftpd", "-M",
(const char )m_puftpfiletransferparams->m_MulticastIp, "-p",
(const char )m_puftpfiletransferparams->m_iPort, "-D",
"/ram/tmp",NULL
Its working fine and I am getting logs UFTP version 4.9.4 Copyright (C) 2001-2017 Dennis A. Bush

I am not getting what else I need to make it work . Do I need to add -k or -K both side , If I am not adding this will it not work ?? What I understood is if I am not using -k it will by default generate 512 bit rsa key.
I am not getting any help regarding this .Please help me to understand it better.
Thanks
Amit
This error is returned if the chosen symmetric key type is not supported by the receiver in question.
Can you show the uftpd logs (including startup) when this happens? My guess is that either it was not compiled with encryption support or the installation of OpenSSL does not support DES.
Similar log I am getting uftpd side .

Please suggest me if i need to enable more logs .
The uftpd log doesn't show any message about loading any keys. That indicates that the client was compiled without support for encryption. You'll need to recompile the client with encryption enabled.
