All Security Tools
31 free, client-side tools for password generation, cryptographic hashing, breach checking, and data encoding.
Which Tool Do I Need?
π I need to create a new password
Use the Password Generator for random passwords or Passphrase Generator for memorable ones.
π I need to check if my password is safe
First check password strength, then check if it appears in known data breaches.
#οΈβ£ I need to hash data or verify integrity
Use SHA-256 for secure hashing, HMAC for authenticated messages. Avoid MD5 for security.
π I need a unique identifier
Use UUID Generator for database keys and resource IDs.
π I need to encode/decode data
Use Base64 for binary-to-text, URL Encoder for query parameters, JWT Decoder for tokens.
