Added

  • PuTTY key support (.ppk, version 3 — the format current PuTTYgen writes):
    import passphrase-protected or plain .ppk files, and export any stored key
    as a .ppk (encrypted with Argon2id + AES-256-CBC when a passphrase is
    given). Covers RSA, Ed25519 and ECDSA (nistp256/384/521). Import/export are
    wired into the Import tab and the Export format dropdown.
  • Sidebar shows the real application icon instead of the [SSH] text badge,
    using an optimized 256x256 PNG derived from the app artwork
    (scripts/make-sidebar-icon.js, npm run icon:sidebar).

Security

  • PuTTY .ppk version 2 files are rejected with guidance to re-save them in a
    current PuTTYgen, because that format derives its key material and integrity
    check with SHA-1.
  • The PPK MAC (HMAC-SHA-256 over the algorithm, encryption type, comment,
    public key and decrypted private blob) is verified timing-safely before any
    key material is returned, so a wrong passphrase or a tampered file never
    yields a usable key. Argon2 parameters from an incoming file are validated,
    with implausible memory requests refused.
