Why set access passwords for important files?
Businesses and individuals alike are increasingly vigilant about the security of their confidential files and personal privacy. Encrypting important files is a common practice to prevent unauthorized access, reading, or modification. Once an access password is set for a file, it must be entered to view or edit the file in the future.
As the demand for file encryption grows, a plethora of methods have emerged. It’s important to select an encryption technique that aligns with your needs.
As more and more people choose to encrypt their important files, various encryption methods have appeared, so how to choose the encryption method that suits you?
Choose your own encryption method and related precautions
Encryption method suitable for transmission
Using software such as WinZip, WinRar, and 7z for compression encryption is a common approach to ensure files are secure for both storage and transmission over the Internet. This method not only reduces the file size but also encrypts the data with a password, leading to savings in storage space and diminished data transfer times, while also delivering content protection.
However, these applications are generally intended for storage and transmission purposes rather than for editing encrypted files. The process of adjusting an encrypted file can prove to be laborious, since it necessitates decryption, decompression, and—following any changes—re-compression, re-encryption, and re-indexing. This is particularly cumbersome if the file in question harbors multiple items. Moreover, several tools capable of opening zip and rar files do not offer functionality to directly edit these files.
The security provided by compression-encrypted formats such as zip and rar is an additional point of concern. The Internet houses a plethora of cracking tools that specifically target these formats, thereby undermining the integrity of the encryption and potentially exposing the encrypted files to unauthorized access.
 advantage |  shortcoming | |
|---|---|---|
| compression encryption | ● Minified files for easy transfer over the network ● Widely supported, most software supports reading the content of compressed files | ● It is not conducive to modification, and it takes a long time to modify a single file. ● For compressed and encrypted formats such as zip and rar, there are many cracking software on the Internet |
Encryption method suitable for modification
When writing and refining critical company documents, such as bids or sensitive program codes, encryption and storage are essential. However, with the need for frequent modifications, efficiency is key. Compression tools like WinZip, though useful for encryption, can lead to significant time loss during edits. To address this, we opt for encryption methods conducive to frequent updating, such as hardware encryption, full-disk encryption, or virtual disk encryption.
- Hardware encryption refers to the encryption capabilities integrated directly within a storage device, which automatically encrypts and stores all incoming data. Access to this data requires the provision of authorized token information. Such security measures are most commonly implemented by large corporations and can become expensive due to the requirement for a comprehensive range of compatible peripherals.
- Full-disk encryption employs software solutions such as BitLocker (which is not supported by all versions of Windows Home) or TrueEncrypt to secure entire disk partitions at the sector level. To access the encrypted data, users must enter the correct password.
- Virtual disk encryption utilizes software programs like Renee SecureSilo to generate a secure, encrypted virtual disk file that can be mounted to a drive letter. Much like a USB flash drive, it can be accessed as needed and secured when not in use. Utilizing virtual loading technology, this method is particularly covert, allowing virtual disk files to be camouflaged as different file types for enhanced secrecy.
Sector-level encryption permits rapid modifications to files as it eliminates the requirement for full decompression. This efficient approach allows for changes or new additions to be saved in under a second. Moreover, this process negates the need for re-indexing and recompression, which markedly reduces processing time in contrast to traditional compression encryption.
 advantage |  shortcoming | |
|---|---|---|
| hardware encryption | ● Fastest encryption and decryption ● Very high security | ● Expensive ● Need a lot of supporting facilities |
| full disk encryption | ● Fast encryption and decryption ● The initial encryption process is long ● Low price, high performance-price ratio | ● Moderate privacy ● Requires a specific version of Windows to use (not all Home versions are supported) ● Average level of security |
| virtual disk encryption | ● Fast encryption and decryption ● You can customize the size of the virtual disk at will ● Can be loaded and closed at any time, with strong privacy ● very cost-effective | ● Average level of security |
Precautions
- Use a memorable password when encrypting files to avoid forgetting it.
- While no encryption is foolproof, opt for professional encryption software with robust security to deter cracking.
- Encrypted files and folders can still be deleted, so back up vital data before encryption.

Method 2: (full disk encryption) use Bitlocker for file encryption
Bitlocker is a data encryption protection function built into the Windows operating system, which can protect the file data inside by encrypting the entire disk.
Notice:
All Windows Home editions do not support BitLocker.
All Windows Home editions do not support BitLocker.
BBitlocker functionality is built into the following Windows versions:
- Windows Vista and Windows 7 Ultimate and Enterprise
- Windows 8 and 8.1 Professional and Enterprise
- Windows 10 Professional, Enterprise and Education editions
- Windows Server 2008 and later systems
Bitlocker encryption steps are as follows:
① Right-click the disk to be encrypted, and select (Turn on Bitlocker) in the right-click menu bar.
② After entering the Bitlocker encryption interface, check (Use a password to unlock the drive), then enter the password and click (Next).
③ To prevent forgetting the password, you can choose a way to save the password, after saving, click (Next).
④ Finally click (Start Encryption) and wait for a while to complete the encryption protection of the entire disk file.
shortcoming
● Due to its limited functions, Bitlocker cannot encrypt a file or folder individually, but can only encrypt the entire disk where the file is located, indirectly achieving the purpose of file encryption. When the user needs to open other files in the disk, he needs to enter the password every time, which is extremely cumbersome. And it doesn't work with Home Edition.

How can VI prevent encrypted important files from being cracked?
To enhance file encryption security, select a robust password to significantly hinder cracking attempts. Remember these key guidelines when creating an encryption password:
- Passwords must be at least 8 characters long.
- Incorporate a mix of upper/lowercase letters, numbers, and symbols to enhance complexity.
- Avoid using identical passwords for multiple encrypted files.
- Refrain from using personal details like your name’s pinyin or birth date as a password.
- Do not use personal information that can be easily found, such as license plate or phone numbers, and home addresses.
For enhanced security, it’s crucial to create a strong password and ensure that details such as character combinations and password length remain confidential. Knowledge of these specifics can significantly narrow down a hacker’s cracking efforts, making it easier for them to breach your password.
To secure files effectively, it’s advisable to utilize professional encryption tools known for robust security features. Software like Renee SecureSilo and Renee File Protector is designed to offer high-level encryption that is resistant to cracking, making them suitable choices for protecting important files.
After we encrypt the file, we can also use Renee File Protector to lock it again to achieve double protection, which can greatly improve the security of the encrypted file and make it difficult for people to crack.
