Secure Your Applications with Developer Security Tools

Enhance security and streamline development with our security and cryptographic tools. Generate strong, cryptographically secure passwords with customizable options, create MD5, SHA-1, SHA-256, and SHA-512 hashes for data integrity, produce unique UUIDs (v1, v4) for database identifiers, decode JWT tokens to inspect claims, and use various encryption helpers. These tools are essential for developers building secure applications, system administrators managing credentials, and anyone who needs reliable cryptographic utilities. All operations run client-side for maximum security - nothing is sent to servers.

All tools run entirely in your browser. No files are uploaded to our server.

Frequently Asked Questions

Everything you need to know

Yes. All processing happens in your browser — nothing is sent to any server. Hashes are computed locally, passwords are generated locally, and JWT tokens are decoded locally.

We support MD5, SHA-1, SHA-256, and SHA-512 hashing. Input any text or string and get the hash output instantly. Useful for checksums, API signature verification, and data integrity checks.

A UUID (Universally Unique Identifier) is a 128-bit ID used in databases, APIs, and distributed systems to uniquely identify records. Our generator produces both UUID v1 (time-based) and v4 (random) formats.

Yes. Our JWT Decoder takes any Bearer token or raw JWT, decodes the header and payload, and displays the claims in readable JSON — no library or backend needed.

Use our Password Generator to create passwords of 8–128 characters using uppercase, lowercase, numbers, and special symbols. Use passwords of at least 16 characters for important accounts.
