## Tools

- [JWK Generator & Parser](https://elysiatools.com/en/tools/jwk-generator): Generate JSON Web Keys (JWK) for RSA, EC (P-256/P-384/P-521/secp256k1), and OKP (Ed25519/Ed448/X25519/X448), or parse an existing JWK to inspect its parameters, thumbprint, and metadata
- [Key Pair Generator](https://elysiatools.com/en/tools/key-pair-generator): Generate public/private key pairs for various cryptographic algorithms
- [RSA Encrypt / Decrypt](https://elysiatools.com/en/tools/rsa-encrypt-decrypt): Encrypt text with an RSA public key or decrypt ciphertext with the matching private key, using OAEP padding (SHA-1 or SHA-256). Handles long messages by chunking. Keys and data stay local. PKCS#1 v1.5 is intentionally not offered (Node disables it for decryption due to Bleichenbacher attacks).
- [RSA Key Pair Generator](https://elysiatools.com/en/tools/rsa-key-generator): Generate an RSA key pair (2048/3072/4096-bit) as PEM-encoded public and private keys. Optionally encrypt the private key with a passphrase. PKCS#8 (recommended) or PKCS#1 private key format. Everything runs locally.
- [SSH Key Pair Generator](https://elysiatools.com/en/tools/ssh-key-generator): Generate an SSH key pair (Ed25519 recommended, RSA 4096, or ECDSA P-256) with an OpenSSH-format public key ready for ~/.ssh/authorized_keys, a SHA256 fingerprint, and a PEM private key. Optional passphrase encryption. Runs locally.
