## Tools

- [AGEX Keypair Generator](https://elysiatools.com/en/tools/agex-keypair-generator): Generate an Ed25519 keypair for AGEX bundle signing and verification
- [Bitcoin Address Generator](https://elysiatools.com/en/tools/btc-address-generator): Generate Bitcoin addresses from private keys for different address types
- [Digital Signature Generator](https://elysiatools.com/en/tools/digital-signature-generator): Sign a message with a private key or verify a signature with a public key — supports RSA-PSS (SHA-256), ECDSA (P-256), and Ed25519. Pure client-side crypto (Node crypto.createSign/createVerify), no network. Paste a PEM key to sign or to verify a base64 signature. This tool signs/verifies; it does not generate key pairs.
- [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.
