About this AES 256 Encryption online tool
The main aim of this tool is to Encrypt and Decrypt given data. For this purpose, we have provided Advanced Encryption Standard (AES) tool with all possible modes like GCM, CBC, ECB, CFB, CTR, OFB with 128, 192,256 Key bit sizes. You just need to enter message, password and then select required dropdowns. Now you have a Encrypted message and you can share it with others.
How to use this free best online AES 256 Encryption tool?
As earlier mentioned, you can make use of our AES 256 Encryption without facing any hassle. You don’t need to take any training or memorize formulas to encrypt or decrypt message. The only thing you need to do is, follow the simple steps mentioned below.
Step 1: After accessing the tool, you will find a text field ie "Message to Encrypt" where first you have to enter your Message (Enter the desired text that should be encrypted). This field is mandatory but there is no minimum or maximum limits for this field for entering message or text.

Step 3: The next thing is to select one of Encryption modes from the "Select Mode" dropdown. Mode CBC (Ciper Block Chaining) is set as default. We have provide 5 modes with GCM as follows
- CBC - Cipher Block Chaining mode
- ECB - Electronic Code Book mode
- CFB - Cipher Feedback mode
- CTR - Counter mode
- OFB - Output FeedBack mode
- GCM - Galois/Counter mode
Step 4: The next thing is to select one of Encryption key Bit size from the "Key Size in Bits" dropdown. 256 Bits is set as default. We have provide 3 bit sizes as follows
- 128 Bits
- 192 Bits
- 256 Bits
Step 5: The next thing is to select one of text format from the "Output Text Format" dropdown. Base64 is set as default. We have provide 2 text formats as follows
- Base64
- Hex
Step 6: Lastly, hit the “Encrypt Now” button. The results will be displayed in "Encrypted Message" card in a blink of an eye. Share this Encrypted Message with the person you want and don't forgot to share the password.
