Security

Passwords, hashes, 2FA and ciphers using browser cryptography.

View all
Caesar and Vigenère cipherEncode messages with Julius Caesar’s cipher, ROT13, ROT47 or Vigenère, and decrypt texts even without the key: we try all 25 shifts and rank the results by how closely each one resembles real text in your language.
Hash generator (MD5, SHA-256, CRC32…)Get the most common hashes of a text or a file at once and compare them with the checksum published by the author to make sure a download is neither corrupted nor tampered with. Files are processed in a Web Worker without uploading them anywhere.
