Passwords, hashes, encryption, encoding and link checks, right in your browser.

Passwords

Create strong random passwords with the length and characters you choose, using your device’s secure random generator.

Test how strong a password is, see an estimated time to crack it, and get tips to make it better.

Create MD5, SHA-1, SHA-256, SHA-384 and SHA-512 hashes of text or a file, and compare them with a hash you have.

Encrypt a message with a password using AES-256, and decrypt it again later. Everything happens in your browser.

Check that a downloaded file is genuine: paste the published checksum and compare it with your file.

Convert text or a file to Base64, or decode Base64 back to text, with an optional URL-safe format.

Encode special characters in a link or a value so they are safe to use in a web address, or decode them again.

Break a link into its parts and see warning signs for phishing, such as look-alike characters and shorteners.
