How AES Text Encryption Works
The Advanced Encryption Standard (AES) is a symmetric-key cryptography algorithm established by the U.S. National Institute of Standards and Technology (NIST). It is the global standard for securing sensitive data, utilized by governments, financial institutions, and cybersecurity professionals worldwide.
This tool utilizes AES via the CryptoJS library. Because it uses symmetric cryptography, the exact same secret key (password) used to encrypt the payload must be utilized by the recipient to decrypt it.
Secure Communication Protocols
- Protect Your Cryptographic Key: Your encrypted data is only as secure as your secret key. We highly recommend using a long, complex passphrase generated by a secure Password Manager.
- Out-of-Band Key Exchange: Never send your secret key to a recipient through the same channel you send the encrypted message. For example, if you email the encrypted text, transmit the decryption key via a secure messaging app like Signal.
- Identify Ciphertext: Encrypted AES output from this tool will appear as a long string of random characters, typically ending in an equals sign (
=). This is Base64 encoded ciphertext. Do not modify any character, or decryption will fail.
