Overview

Generate SSH key pairs and derive public keys and inspect SSH certificates.

A secure, offline-capable Chrome Extension for generating SSH key pairs, deriving public keys, inspecting SSH certificates, and converting private keys between OpenSSH, PEM (PKCS#1/PKCS#8), and PuTTY PPK formats — directly in your browser. **Features** - Generate SSH Keys: Supports RSA (2048/4096-bit), ECDSA (nistp256/384/521), and ED25519. - Passphrase Protection: Encrypt private keys with a passphrase using robust OpenSSH encryption. - Public Key Derivation: Derive the associated public key from an existing private key. - SSH Certificate Inspection: Inspect details of SSH certificates (Key ID, Principals, Validity, Extensions, etc.). - Key Format Conversion: Convert private keys between OpenSSH, PKCS#1, PKCS#8 (PBES2 with PBKDF2-SHA256 + AES-256-CBC), and PuTTY PPK v2 formats. Add, remove, or change passphrases in one step. - Offline & Secure: All cryptographic operations happen locally within the extension. No keys are ever sent to any server. - Modern UI: Clean, responsive interface with Dark Mode support.
