Security & Cryptography Tools
Strong security starts with good tools. Our security utilities help you generate robust passwords, compute cryptographic hashes, create HMAC signatures, and build htpasswd files — essential tasks for developers, system administrators, and anyone who takes digital security seriously.
The password generator creates strong, random passwords with customizable length, character sets, and entropy analysis. The hash tools support MD5, SHA-1, SHA-256, SHA-512, and other algorithms for file verification and data integrity checks. Every tool operates entirely in your browser — nothing is transmitted over the network.
Whether you are setting up server authentication, verifying file checksums, or generating secure random strings for API keys, these tools give you reliable results with zero installation overhead.
Frequently Asked Questions
Are passwords generated on my device or your server?
All passwords and random strings are generated entirely in your browser using cryptographically secure random number generators. Nothing is transmitted over the network.
Which hash algorithms are supported?
We support MD5, SHA-1, SHA-256, SHA-384, SHA-512, and HMAC variants. SHA-256 is the recommended choice for most modern use cases.
Can I use these tools for production security tasks?
Yes. The password generator, hash tools, and htpasswd generator produce output suitable for production use. The underlying algorithms are standard implementations.
What is password entropy and why does it matter?
Entropy measures the randomness of a password in bits. Higher entropy means the password is harder to guess or brute-force. A password with 80+ bits of entropy is considered very strong for most applications.
