Document Decrypt Tool

Introduction

Document Decrypt is a free online text decryption tool that supports multiple decryption methods including Base64, ROT13, and more. Decrypt text with one click to quickly restore encrypted or encoded content.

Main Features

1. Multiple Decryption Methods

Support Base64, ROT13, and password decryption

2. Base64 Decryption

Decode Base64 encoded text

3. ROT13 Decryption

Restore ROT13 encrypted text

4. Password Decryption

Decrypt XOR encrypted content using password

5. Error Messages

Display clear error messages when decryption fails

6. One-Click Copy

Copy decrypted results to clipboard with one click

How to Use

1. Enter or paste the ciphertext to decrypt in the input box
2. Choose decryption method (must match the encryption method used):
   • Base64: Decode Base64 encoding
   • ROT13: Restore letter substitution cipher
   • Simple Decrypt: XOR decryption, requires password
3. If choosing password decryption, enter the same password used for encryption
4. Click the "Decrypt" button
5. View the decrypted result, click "Copy Result" to copy to clipboard

Use Cases

• Data Restoration: Restore Base64 encoded data
• Text Decryption: Decrypt ROT13 encrypted text
• Content Recovery: Recover simply encrypted content
• Encoding Conversion: Convert encoded text back to original format

FAQ

What to do if decryption fails?

Please ensure:

1. The input is valid ciphertext
2. The chosen decryption method matches the encryption method
3. The password for password decryption is the same as used for encryption
4. For Base64 decoding, the input is a valid Base64 string

What is the difference between Base64 and ROT13?

Base64 is an encoding method used to convert binary data into ASCII strings. ROT13 is a simple substitution cipher that replaces letters with the 13th letter after them. Both are reversible and can be restored through the corresponding decode/encrypt operation.

Why does the decrypted result not match expectations?

Possible reasons include:

• Wrong decryption method selected
• Incorrect password entered
• Input is not valid ciphertext
• Text was modified during transmission or copying

Please check the above factors carefully and try again.
