Secure Personal Archive (Spa 2.5)

The secure personal archive provides security tools for a computer.

  • As a self-contained archive Spa keeps sensitive information secure. Items are accessed through a directory tree accessible only by a password.

  • Convenient drag-and-drop file cryptography is provided from keys within the archive.

  • Random passwords (or keys) can be generated from an FM radio by the Trap tool.

  • A wide variety of file hashes (MD5, SHA-1, ... ) can be calculated via the FileHash tool.
