# This snippet demonstrates how to send and receive data
# encrypted with openssl using netcat.

# You can also substitute 'nc' for another tool.

yubikey w/ ssh on macOS notes

Trade offs

• FIDO2 (AKA, "security key" / "sk") key:
  • You really need physical presence (need to tap the yubikey - no prompts)
  • Odd workflow even with ssh-agent for Go due to lack of tap prompt

  • OpenSSH added FIDO2 support recently (8.2, early 2020 - see ssh -V)
• PIV (Personal Identity Verification) key:
