jakobhusu ee278d8c07 Remove timestamp — 24-word mnemonic alone is sufficient for recovery 2026-05-20 11:53:38 +02:00
jakobhusu f76a773433 Add generation timestamp as a second factor for key derivation 
Key seed is now derived via HKDF(entropy, salt=timestamp), so recovery
requires both the 24 mnemonic words and the exact UTC timestamp shown
at generation time. Wrong timestamp produces a completely different key.

jakobhusu 1ff771a62a Default key output to ~/.ssh/ and create the directory if needed 2026-05-20 11:33:12 +02:00
jakobhusu b857aa3afb Add SSH key generator with BIP39 mnemonic backup 
Generates Ed25519 SSH keys and encodes the private key seed as 24 BIP39
words for safe offline storage. Keys can be fully recovered from the
mnemonic alone.
