RSA Keys (RS256) ▼

Generates an RSA key pair (RS256 algorithm). Useful for signing and verifying JWTs (JSON Web Tokens), general data signing, and asymmetric encryption. The PKCS8 format is common for private keys, while JWK is standard for public keys in web contexts, especially within a JWKS (JSON Web Key Set) endpoint for token verification.

RSA Keys (2048-bit, PEM) ▼

Generates a standard 2048-bit RSA key pair using Node.js crypto and provides the keys in PEM format. SPKI (SubjectPublicKeyInfo) is used for the public key and PKCS#8 for the private key. This format is commonly used by tools like OpenSSL.

ECDSA Keys (ES256) ▼

Generates an ECDSA key pair using the P-256 curve (ES256 algorithm). Often preferred over RSA for JWT signing due to smaller key sizes and comparable security. Like RSA, PKCS8 is used for the private key and JWK for the public key/JWKS.

UUIDs ▼

Generates a Version 4 UUID (Universally Unique Identifier), which is based on random numbers. Commonly used for unique database IDs, transaction IDs, etc.

Hashes ▼

Enter text below to automatically calculate its cryptographic hashes on the server. Used for data integrity checks, password storage (use Argon2/bcrypt), and indexing. Note: MD5/SHA1 are weak; prefer SHA256/SHA512.
