Protect your sensitive data. Use military-grade AES encryption to scramble text with a custom password instantly, entirely within your browser.
Send passwords over Slack or email safely. Your secrets never touch our databases.
The Advanced Encryption Standard (AES) is the exact same cryptographic algorithm approved by the NSA to protect top-secret government classified information.
Because the math is executed locally via JavaScript within your browser's CPU sandbox, we physically cannot log, intercept, or steal your passwords or your data.
The exact same password used to lock the message is required to unlock it. This allows you to easily share the password out-of-band (like over a phone call) with the recipient.
Encryption is the mathematical process of encoding information so that only authorized parties can read it. Unlike hashing (which is a one-way street meant to permanently destroy a password), encryption is a two-way street. Data is scrambled into ciphertext using a mathematical algorithm, and it can only be unscrambled back to plain text by someone holding the correct cryptographic key.
When you use an online text encryptor, the industry standard algorithm is AES (Advanced Encryption Standard). AES operates on a system of mathematical substitution and permutation blocks.
If a hacker intercepts your encrypted message (e.g., U2FsdGVkX1+...), they cannot read it. The only way to break AES-256 is via a "Brute Force" attack—meaning a computer must guess every single possible password combination until it finds the right one.
With a 256-bit key length, there are 2256 possible combinations. That number is larger than the number of atoms in the observable universe. If a hacker utilized all the computing power currently available on Earth, it would still take them billions of years to guess the key. The math is flawless.
While the AES algorithm is unbreakable, human behavior is not.
The strength of encryption completely depends on the strength of your "Secret Key" (your password). If you encrypt a multi-million dollar corporate contract, but you set the password to 123456, a hacker's software will guess that password in less than a millisecond, completely bypassing the massive AES mathematical defenses. Always use a long, complex, completely random password generated by a secure password manager.
Why go through the trouble of encrypting text before sending it to a coworker?
