v1.4.0 — RSA-SHA256 Auth & EC2 .pem Key Support

RSA-SHA256 authentication now supports AWS EC2 .pem keys. Includes jump host RSA auth and port forwarding fixes.

🆕 New Features

🔑 SSH Key Import (EC2 .pem Support)

  • Supports PKCS#1 format (-----BEGIN RSA PRIVATE KEY-----) and OpenSSH format
  • Paste a .pem file and connect directly to EC2

🔐 rsa-sha2-256 Authentication (RFC 8332)

  • Connect even in environments where ssh-rsa (SHA-1) is disabled on OpenSSH 8.8+
  • PKCS#1v15+SHA-256 signing via Apple Security.framework

🌐 Jump Host RSA Authentication

  • RSA authentication upgraded to SHA-256 for both jump hosts and targets (e.g. EC2)
  • Mac Mini → EC2 configurations now work

🐛 Bug Fixes

  • Fixed port forwarding data loop (resolved SSH→TCP→SSH→TCP… infinite loop)
  • Improved performance (batch flush via channelReadComplete)
  • Snippet tabs are now horizontally scrollable
  • +button is now fixed to the right edge outside the ScrollView
