Support OpenSSH certificate-based authentication (-cert.pub files) in
the Credentials manager. When a CA-signed certificate is stored alongside
a private key, Termix uses it during SSH connection establishment so that
servers relying on certificate-based authorization work out of the box.
Changes:
- db/schema.ts: add cert_public_key column to ssh_credentials table
- db/index.ts: auto-migration via addColumnIfNotExists
- routes/credentials.ts: expose certPublicKey in create/update/get endpoints
- ssh/auth-manager.ts: include certPublicKey in ResolvedCredentials
- ssh/host-resolver.ts: propagate certPublicKey when resolving credentials
- ssh/opkssh-cert-auth.ts: refactor shared logic into _applyCertToConnection;
export new setupCACertAuth() with optional passphrase support
- ssh/terminal.ts: call setupCACertAuth() when a certificate is present
- utils/ssh-key-utils.ts: detect all OpenSSH cert types in public key parser
- types/index.ts: add certPublicKey to Credential, CredentialBackend,
CredentialData interfaces
- CredentialAuthenticationTab.tsx: new CA Certificate section with file
upload, paste editor and automatic cert-type badge
- CredentialEditor.tsx: certPublicKey wired into form schema and submit
- CredentialViewer.tsx: show certificate status in security tab
- locales/en.json: add i18n strings for new UI elements
Replace hardcoded setTimeout timing with exec channel polling for
reliable tmux session readiness detection. Add meaningful session
naming (termix-<hostId>-<rand>), aggressive-resize for multi-client
support, and a detach button in the terminal UI.
