Military-Grade Text Encryption
When sending sensitive information over unsecured channels, proper encryption is vital. Our AES Encryption Tool utilizes the Advanced Encryption Standard (AES)—the same cryptographic algorithm trusted by governments and banks—to secure your text data.
How AES Encryption Works
AES is a symmetric-key algorithm, meaning the same secret key/password is used for both encrypting and decrypting the data. Our tool supports robust modes (like CBC and GCM) to ensure maximum security against tampering and cryptanalysis.
Crucial Security Warning
If you lose your secret key, it is mathematically impossible to recover the encrypted data. We do not store your passwords, so please keep your keys safe.

Frequently Asked Questions
Is this tool truly secure?
Yes, the encryption process utilizes the Web Crypto API, executing 100% client-side. We never see your text or your secret key.
Does it use AES-128 or AES-256?
By default, the tool derives a robust 256-bit key from your provided password, offering the highest level of AES security.
Can I decrypt data encrypted by other AES tools?
Yes, as long as the other tool used standard AES parameters (like PBKDF2 for key derivation) and you provide the correct Salt and Initialization Vector (IV).
