Security tools: 6 free file encryption tools

By compressing files and setting passwords, it is still possible to crack them by running software. Therefore, we have introduced 6 free file encryption tools, encryption of confidential files is a common practice to protect confidential data. The most common method is to compress files and set a set of unzipping passwords, only those who know the password of the restricted file have the permission to read the file. In most cases, the above method can effectively protect the security of files and materials, but it is still possible to use the software operation method to crack it mainly through the dictionary file method). Therefore, it is necessary to encrypt data using more robust tools.

In addition, the deletion of files may be restored even if the files have been cleared from the resource recycle bin, as a result, many of these tools provide the ability to remove files from the hard drive to prevent leakage of data due to legacy data.

6 free file encryption software

In addition to a single encryption product, some enterprise-side anti-virus software has begun to include this feature in, but it can encrypt files using free tools, there are many kits developed by zi'an plant. We have selected six of them for introduction this time.

Axon Data AxCrypt 1.6.4.4

AxCrypt is an open source code file encryption tool. Among the tools of the same type we tested this time, it is a complete suite of functions.

AxCrypt allows us to right-click the menu and use the AES algorithm to encrypt the selected file, which is very easy to operate. At the same time, it can be set to retain the original data, create or delete only one encrypted copy.

In addition, the software can be packaged into an automatic execution file, which can be decrypted on a computer without AxCrypt installed.

It also provides the ability to remove files. We can delete files after processing them through AxCrypt, and use double steps to effectively protect the security of confidential data.

InterCrypto Crypt4Free 5.1.6

Crypt4Free is a set of encryption tools with file encryption and compression. Through its application interface, we can use one of the two algorithms, DESX and Blowfish, to encrypt files, or package it into a ZIP file.

In particular, Crypt4Free provides the virtual keyboard function. When we set encryption for files, this function can prevent the decrypted password from being recorded by malicious programs.

Like most other tools, we can delete original data when encrypting files to prevent unauthorized file outflow and cause information security vulnerabilities.

Since this tool does not provide the ability to create execution files, if you want to decrypt files created by it on other computers, you must install the Crypt4Free main program.

2 BrightSparks EncryptOnClick 1.3.1.3

In the application interface of EncryptOnClick, there are only two function keys available for operation, including encryption and decryption. In addition, there are no other setting options. Among the six file encryption tools we tested this time, this is the easiest way to operate.

Objects that can be encrypted include folders in addition to a single file. During the test, we encrypt a folder containing more than 100 files. After the encryption is completed, all the data will be converted into an encrypted file named. EOC.

Because it does not support packaging and self-decryption of the execution file, we must install the EncryptOnClick main program on other computers to identify the encrypted file format and then decrypt the file.
