~ smansoft ~ Leave a comment

File Exchanger Tool 0.0.11.11 has been released.

Supported platforms:

  • Windows (x86, x86_64)
  • Linux (x86_64)

File Exchanger – 0.0.11.11 – Linux
File Exchanger Tool – 0.0.11.11 – Windows

Please, see screenshots here: screenshots.
Here are: demo (screenshots (.jpg), video demo (install, run) (.mp4)).

File Exchanger (file_exchanger) Tool is a peer-to-peer files exchanger for Windows/Linux platform.

Overview
—————-
The main features of File Exchanger (file_exchanger) Tool:

  • transfer of files from client to server, using open socket connections;
  • transfer of files from client to server, using SSL connections;
  • control of entirety of received files, comparing of checksum values sent and received files, using CRC-32 algorithm;
  • using transfer of files from client to server, using SSL connections;
  • using follow SSL mode/algorithms (TLSv1.2), if SSL connection is used:
    • ECDHE-ECDSA-AES256-GCM-SHA384
    • TLSv1.2 – version
    • TLS – the protocol used
    • ECDHE – the key exchange mechanism
    • ECDSA – the algorithm of the authentication key
    • AES – the symmetric encryption algorithm
    • 256 – the key size of AES
    • GCM – the mode of AES
    • SHA384 – the MAC used by the algorithm
    • prime256v1 (NIST P-256, secp256r1) – Elliptic Curve, that is used by ECDHE and ECDSA
  • using unique CA of client and server certificates;
  • user can update CA, client/server/gui keys/certificates, using suite of scripts ssl.ecdsa.tar.gz (ReadMe.txt in ssl.ecdsa.tar.gz);
  • using of xml configuration files, which can be updated by user and will be applied without restart of processes (sm_file_send_clns, sm_file_send_srvs);
  • scanning of configured directories, where sent files can be copied;
  • copying of sub-directories with files, saving of sub-directories tree at the server side;
  • support of unicode symbols in file/directory names;
  • backup (with rolling) of sent/received files;
  • server and client modules can be launched as Services (Windows)/Daemons (Linux);
  • console command line control application (only Windows) of client/server Services (requires Administrator permissions);
  • Windows gui application (asynchronous multi-thread GUI), that allows to monitor states of client/server Services, control of client/server Services and change parameters of client/server Services;
  • Linux gui application (Qt-based) (asynchronous multi-thread GUI), that allows to monitor states of client/server Daemons, control of client/server Daemons (when it’s possible, according to users permissions) and change parameters of client/server Deamons;
  • using ECDSA (NIST P-256, secp256r1) for signing/verification parameters, which are sent between client/server and gui applications (Windows/Linux);
  • tool applications don’t use any intermediate servers and transfer files directly between client and server;

SSL ECDSA scripts is a suite of scripts for generation X.509 keys/certificates.

Overview
—————-

The main features of SSL ECDSA scripts:

  • generation of CA key and Self-Signed CA Certificate;
  • generation of SSL private key, public key and sign public key, using CA key and generation of X.509 certificate of server (server certificate);
  • generation of SSL private key, public key and sign public key, using CA key and generation of X.509 certificate of client (client certificate);
  • generation of SSL private key, public key and sign public key, using CA key and generation of X.509 certificate of gui applications (client certificate);
  • usage of Elliptic Curves (ECDSA-WITH-SHA384) prime256v1 (NIST P-256, secp256r1) for signing of public keys;
