About </>

SecureBox Pro is an application that offers secure shell(ssh) commands and additional commands for management of keys, X.509 certificates, digests and etc. As specified in RFC4251: "Secure Shell (SSH) is a protocol for secure remote login and other secure network services over an insecure network."

Same as non-professional version, SecureBox Pro is packaged with complete list of PKIX-SSH and OpenSSL commands. Unlike non-professional version, application is bundled with terminal emulator and user interface(screens) for management of secure shell connections, identities, sessions and etc.

From application screens user could define parameters of secure shell connections and directly to open secure shell connections(sessions). Each ssh session is opened in separate terminal window. Terminal windows(sessions) could be switched with swipe gesture or directly from navigation menu.

Another application screens simplify management of user identities(ssh keys) used in "Public Key Authentication Method". Management includes export interface to share(send) public part of key to administrator of secure-shell servers.

Application offers access to local console(terminal). Local terminal uses build-in into each android device born-shell. User could use system set of shell command to manage files, processes, device and etc. As well user could use all commands packaged by application.

Bundled PKIX-SSH offers widest range of supported key algorithms, chippers, macs for secure shell protocol. Supported public key algorithms, based on plan public keys, are:

  • EC : ecdsa-sha2-nistp256,ecdsa-sha2-nistp384,ecdsa-sha2-nistp521
  • RSA : ssh-rsa,rsa-sha2-256,rsa-sha2-512
  • Ed25519 : ssh-ed25519
  • DSA : ssh-dss
All those algorithms are managed and used from application screens.

In addition PKIX-SSH supports algorithms based on X.509 certificates:

  • EC : x509v3-ecdsa-sha2-nistp256, x509v3-ecdsa-sha2-nistp384, x509v3-ecdsa-sha2-nistp521
  • RSA : x509v3-sign-rsa,x509v3-ssh-rsa
  • DSA : x509v3-sign-dss,x509v3-ssh-dss
Currently this set of algorithms could be used only in client connections opened from local terminal window.

OpenSSL command line tool provides auxiliary commands for management of keys, X.509 certificates, digests and etc. It includes, but is not limited to,

  • key management commands like ec and ecparam, rsa, dsa and dsaparam, genpkey and pkey,
  • commands for management of X.509 certificates, revocation list and authorities - x509, crl and ca,
  • commands for key data management - pkcs12, pkcs8 and pkcs7,
  • commands for operation will keys - pkeyutl,
  • time stamping authority tool - ts.

  • 29 Apr 2019
    Version 2.2.1:
  • 19 Apr 2019
    Version 2.2.0:
    • Packaged with PKIX-SSH 12.0 and OpenSSL 1.1.1b.
    • Default RSA sizes to 3072 bits and more acceptable sizes in range 2^11 - 2^13.
    • Upgrade emulatorview to 1.3.1 (more precise "text" selection based on real start and end points).
    • New preferences "Version" and "User Guide"(opens user guide on site).
    • Migrated to AndroidX.
  • 21 Mar 2019
    Version 2.1.0:
    • Import SSH identity send by external application.
    • Simplify "launcher" icons.
    • Show import related messages on top of screen.
    • Ensure that application works on devices without touchscreen (like Chromebooks).
    • Always visible scroll-bar in "File Selection".
  • 20 Dec 2018
    Version 2.0.0:
    • Material design rules.
      Use only vector graphics with "primary" color (Blue Gray palette). As secondary (accent) is used color from Light Green palette. Button style changed to use those colors.
    • New exported activity "File Selection".
      Used on "pick" request and returns selected file. It is available for use by other applications.
    • Import identify from external sources.
      Details activity allows identify to be imported. Process support import from sources in PKCS#12, PKCS#8 or legacy format. If import file is password protected user is prompted for password. After successful import user has to register (save) identity for use by application. Note that identity registration always requires a password.
      Note that import from PKCS#12 may activate X.509 public key algorithms in secure shell session. Identity distinguished name (certificate subject) is displayed in identity "Detail" activity. Remark: also legacy format may contain X.509 certificates.
    • Manage exit status if session is terminated by signal.
    • Settings activity with action bar.
    • Stop creation of extra files with fingerprint and "ascii art image" identity details.
      Note existing files are cleaned-up on initial start of application.
    • Packaged with PKIX-SSH v11.6.
      Fixed crash on 64-bit Android OS-es. For other improvement see PKIX-SSH pages.
    • Do not store empty "extra" configuration attribute.
      It could happen if user opens "Expert" section and press [Save] button. Work-around is user manually to remove such "extra" empty attribute before to save.
    • Fix load of DSA and ED25519 identities on initial start of application.
    • Prevent rename of identity if is used by a connection.
  • 19 Oct 2018

    • Target compatibility with Android 9.0 (Pie, API 28).
      This implies minimum supported version Android 4.0 (Ice Cream Sandwich, API 14)
    • Notification channel
      Android 8.0 (Oreo, API Level 26) requires service notification to register notification channel.
    • "External Storage" permissions.
      Includes permission request at run time for Android 6.0 (Marshmallow, API 23) and newer.
      Remark: If granted user could manipulate files stored on sdcard.
