Security tools
Generate strong credentials, calculate checksums, protect authorized PDFs, or share an encrypted one-time secret. These tools have different security goals: hashing is not encryption, and a generated password still needs safe storage.
Choose a focused utility below. Every tool page documents how to use it, where its data is processed, realistic limitations, and related workflows so you can make an informed choice before providing input.

Password Generator
Generate strong passwords and memorable passphrases. Create random passwords or word-based passphrases with an entropy estimate. Generation happens in your browser.
Hash Generator
Calculate hashes for text and files. Generate MD5, SHA-1, SHA-256, SHA-384, or SHA-512 digests for text and local files.
Common security tasks
- Generate a unique password or passphrase
- Compare a file with a SHA checksum
- Encrypt or unlock an authorized PDF
- Send encrypted ciphertext with one retrieval
Relevant guides
- How to combine and organize PDF pages — Merge files, put pages in order, rotate mistakes, and export a new PDF without overwriting the originals.
- How to generate and handle strong passwords — Use browser-generated randomness, favor length and uniqueness, store credentials safely, and understand what a one-time secret link protects.
Security tools FAQ
Where should I store a generated password?
Use a reputable password manager, keep every account password unique, and enable multi-factor authentication where available.
Can a hash be used to store passwords?
A plain digest is not suitable password storage. Use a dedicated salted password-hashing function in an application.
What does Secret Share store?
It stores encrypted ciphertext, an IV, verifier, and expiry until a verified claim or cleanup. The decryption key stays in the URL fragment.
