🔐Text Encryption/Decryption

Encrypt and decrypt text using AES encryption.

Text to Encrypt

Password

About

Uses AES-256-GCM encryption via the Web Crypto API
Password is derived using PBKDF2 with 100,000 iterations
Each encryption uses a unique random salt and IV
All processing happens in your browser - nothing is sent to any server

About Text Encryption/Decryption

Text Encryption/Decryption uses AES (Advanced Encryption Standard) — the industry-standard symmetric cipher — to encrypt any text with a password of your choice, all within your browser. Share encrypted text securely, knowing only someone with the correct password can decrypt it.

How to Use Text Encryption/Decryption

1
Enter the text to encrypt
Paste or type the sensitive text you want to encrypt into the input field.
2
Set your encryption password
Enter a strong password that will be used to encrypt and later decrypt the text. Keep this password secure.
3
Copy and share the ciphertext
Click 'Encrypt' to generate the encrypted output, then copy and share it securely. To decrypt, paste the ciphertext, enter the same password, and click 'Decrypt'.

Common Use Cases

Encrypting sensitive notes before storing them in a shared or cloud location
Securely transmitting passwords or API keys via unencrypted channels
Protecting personal data in text files before backing them up online
Learning and demonstrating AES encryption in security courses

Frequently Asked Questions

How secure is AES encryption?

AES-256 is the gold standard in symmetric encryption, used by governments and security professionals worldwide. With a strong password, AES-256 encrypted text is computationally infeasible to brute-force with current technology.

What happens if I forget my encryption password?

There is no password recovery — AES encryption is designed so that the ciphertext cannot be recovered without the correct password. Always store your password securely separately from the encrypted data.

Can I decrypt text encrypted by other AES tools?

AES-encrypted text from other tools may be compatible if they use the same mode (CBC or GCM), key derivation function, and IV scheme. The tool uses standard parameters for broad compatibility.
