Encrypting data is a very important process in order to protect sensitive information from being accessed by unauthorized entities. But sometimes, we may need to decrypt the data for various reasons, such as recovering forgotten passwords or accessing encrypted files acquired through legal means. In this article, we will be discussing ways to decrypt encrypted files and passwords, and the tools that can be used for the same.
Decrypting Excel Passwords
A common scenario in which decryption may be required is when we forget the password to an Excel file. There are many tools and software available on the internet that can help us remove the password protection on an Excel file. Some of the popular ones are:
iSumsoft Excel Password Remover

FAQ
1. Is it legal to decrypt encrypted files?
It is legal to decrypt encrypted files as long as the files belong to you or you have obtained them through legal means. However, it is illegal to use password cracking tools to access files that do not belong to you without permission.
2. Can all encrypted files be decrypted?
No, not all encrypted files can be decrypted. Encrypted files are secured using various encryption algorithms, and decryption is only possible if the algorithm is known and a tool is available that can decrypt the file using the algorithm.
