AES Encrypt & Decrypt helps you handle security and cryptography tasks quickly and accurately, right in your browser. Whether you need to encrypt and decrypt text using aes-256-gcm with a password-based key, this tool eliminatesexposure of sensitive data and security misconfigurations by giving you instant, reliable results. Every operation runs locally on your device — nothing is uploaded to any server, so your data stays completely private.
How to Use AES Encrypt
Enter your text
Type or paste the text you want to encrypt, or paste ciphertext to decrypt.
Set a password
Enter a strong password used to derive the encryption key via PBKDF2.
Encrypt or decrypt
Click Encrypt to secure your text or Decrypt to recover the original plaintext.
Key Features
AES-256-GCM
Industry-standard authenticated encryption with 256-bit keys in Galois/Counter mode.
Password-Based Key
Your password is converted to a 256-bit key using PBKDF2 with a random salt.
Authenticated Encryption
GCM mode provides both confidentiality and integrity verification.
Local Only
All encryption happens in your browser using the Web Crypto API — nothing is sent to any server.
Common Use Cases
- Encrypting sensitive configuration data and environment variables for secure storage
- Protecting personal or confidential text data before transmission over untrusted networks
- Securing backup data and API credentials with password-based encryption

What is AES Encrypt & Decrypt?
AES Encrypt & Decrypt is a browser-based security tool that encrypt and decrypt text using aes-256-gcm with a password-based key. It offers AES-256-GCM, Password-Based Key, Authenticated Encryption — all processed locally on your device. Because no data is ever uploaded, you can handle sensitive information like passwords, tokens, and encryption keys with complete confidence.
Security tools that send data to remote servers introduce unnecessary risk. AES Encrypt takes a different approach: every cryptographic operation, token inspection, and password generation happens right in your browser using JavaScript. This means your secrets never leave your computer, making the tool suitable for handling production credentials, personal encryption keys, and sensitive authentication tokens.
Frequently Asked Questions
What encryption algorithm is used?
AES-256-GCM (Advanced Encryption Standard with 256-bit key in Galois/Counter mode).
How is the encryption key derived?
Your password is combined with a random salt using PBKDF2 with 600,000 iterations.
Is my data sent to a server?
No. All encryption and decryption happens entirely in your browser using the Web Crypto API.
Can I decrypt with other tools?
Yes, AES-256-GCM is a standard — any compliant tool with the same password and IV can decrypt.
How does the AES-256-GCM feature work?
The AES-256-GCM feature industry-standard authenticated encryption with 256-bit keys in galois/counter mode. It is designed to be intuitive and responsive, giving you immediate feedback as you interact with the tool. All processing happens locally in your browser.
What is the benefit of password-based key?
Password-Based Key your password is converted to a 256-bit key using pbkdf2 with a random salt. This capability sets AES Encrypt apart from basic alternatives by providing more comprehensive functionality while maintaining the privacy and speed of local processing.
Is AES Encrypt really free to use?
Yes, AES Encrypt is completely free with no hidden charges, no sign-up requirements, and no usage limits. You can use it as often as you need, for any purpose — personal projects, commercial work, or educational use. There are no premium tiers or paid features.
Does AES Encrypt work on mobile devices?
Yes, it works on any device with a modern web browser — desktop, tablet, or phone. The interface is responsive and adapts to your screen size. Since all processing is done locally, you get the same performance regardless of your device.
What happens to my data when I use AES Encrypt?
Your data never leaves your device. Every operation is performed locally in your browser using JavaScript. No information is uploaded, stored, logged, or shared with any server. This privacy-first approach means you can work with sensitive data — passwords, API keys, personal information — without any risk of exposure.

Tips & Best Practices
Use a strong password
AES-256-GCM is only as secure as your password. Use a long, random password or passphrase. This tool uses PBKDF2 with 600,000 iterations.
Keep the IV with the ciphertext
The initialization vector (IV) is required for decryption but does not need to be secret. Store it alongside the encrypted data.
