Tool hub
Use focused crypto utilities for hashing, encoding, random generation, and learning which tool fits your task. The first tools in this section are designed to run locally in the browser whenever possible.
Featured tools from the current production slice. The catalog lists every page with a search filter.
Generate a SHA-256 hash in your browser. Input stays on your device and is processed with the Web Crypto API.
Generate MD5 hashes for legacy checksums and learn why MD5 should not be used for security-sensitive work.
Encode and decode Base64 text in your browser, with clear notes about what Base64 is and is not.
Generate strong random passwords in your browser using cryptographically secure random values.
Generate cryptographically secure random hexadecimal strings in your browser. Fast alternative to `openssl rand -hex 32` for 32-byte (64-character) values.
Generate SHA-256 hashes for local files in your browser without uploading file contents.
Tools in this section process input on your device in the browser. Static pages are readable without account creation or server-side execution.
The initial crypto tools are designed to run in the browser. Hashing, Base64 conversion, and random generation can happen locally without sending your input to a server.
No. Hashes are one-way fingerprints for data integrity and comparison. Encryption is reversible with a key; hashing is not.
Use SHA-256 for integrity checks, Base64 for text-safe encoding, random password for account credentials, and random hex for token-like values.
These pages are practical references and browser tools, not compliance guarantees. Regulated or high-risk systems still require architecture review and policy controls.
Browser tools are excellent for local processing and education, but they do not replace backend key management, access controls, and audited security workflows.
