What is the meaning of Encryption?

The process of converting message or file into a code or symbols, so that only authorised persons can access it.

In cryptography, encryption is the process of converting original text (also know as plaintext) into secret code (also know as chipertext) that hides the true meaning of text.

AES Encryption belongs to Symmetric ciphers, which use the same keys for both encryption and decryption of a message. They are designed to be easily computable and able to process even large messages.

AES was established by the U.S NIST in 2001. AES is widely used today as it is a much stronger than DES and triple DES despite being harder to implement.


About this free online Encryption/Decryption Files tool

The main aim of this tool is to Encrypt and Decrypt given any file like zip, pdf, word, excel, document, image, text, json, java, apk, 7z,... . 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 upload file, password and then select required dropdowns. Now you have a Encrypted file and you can share it with others.


How to encrypt file or password protect pdf, excel, word, csv, zip, 7z, rar, jpg, jpeg, png, image, jar, war, html, xml, json, mp3, mp4, audio, video, text,... files with this free best online Advance Encryption tool?

As earlier mentioned, you can make use of our AES Encryption without facing any hassle. You don’t need to take any training or memorize formulas to encrypt or decrypt files. The only thing you need to do is, follow the simple steps mentioned below.

Step 1: After accessing the tool, you will find a file upload field ie "Upload File to Encrypt" where first you have to upload file (Upload the desired file that should be encrypted). This field is mandatory but at a time you can upload only one file and encrypt it.

Step 2: The next thing is to enter password or secret key in "Password" text field. While decrypting this same file, you must use this password. This field is also mandatory but there is no minimum or maximum limits for this field for entering password.

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
If you don’t want to change it, leave this step, and follow the next one.

Step 4: The next thing is to select one of Encryption key Bit size from the "Key Size in Bits" dropdown. 128 Bits is set as default. We have provide 3 bit sizes as follows

  • 128 Bits
  • 192 Bits
  • 256 Bits
If you don’t want to change it, leave this step, and follow the next one.

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
If you don’t want to change it, leave this step, and follow the next one.

Step 6: Lastly, hit the “Encrypt Now” button. As a result, "Download Now" button will be visible. Click on it to download file. Share this Encrypted File with the person you want and don't forgot to share the password.
