About </>

Secure Box is an application that offers additional commands for terminal applications. Package includes secure shell commands (client, key management, file transfer, agent, daemon) and commands for management of keys, X.509 certificates, digests and etc.

The Secure Shell (SSH) is a protocol for secure remote login and other secure network services over an insecure network. It is intended to provide secure encrypted communications between two untrusted hosts over an insecure network.

Main features </>

Secure shell commands are port of PKIX-SSH (feature richest ssh implementation in the world) to Android platform. PKIX-SSH offers widest and up to date range of supported key algorithms, chippers, macs for secure shell protocol.

For instance supported public key algorithms include X.509 certificate based keys:

  • EC : x509v3-ecdsa-sha2-nistp256, x509v3-ecdsa-sha2-nistp384, x509v3-ecdsa-sha2-nistp521
  • RSA : x509v3-sign-rsa, x509v3-ssh-rsa, x509v3-rsa2048-sha256
  • DSA : x509v3-sign-dss, x509v3-ssh-dss

As well it support public key algorithms based on plan public keys:

  • 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

Client and server support extension negotiation mechanism. This Feature in used in adaptive public key algorithm selection.

Auxiliary commands for management of keys, X.509 certificates, digests and etc are provided by OpenSSL command line tool.

This list of commands includes, but 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.

The complete list of commands including manual pages is available on application web-site.

Application is best integrated with terminal "TermOne Plus" - it requires "TermOne Plus" permission "Override path" to be granted to it. Also "Override path" has to allowed in "TermOne Plus" preferences.
