According to NI technical documentation , LabVIEW does encrypt the block diagram. Instead:
Based on these hints, the user recalls that their password is a combination of their company name, a year, and a special character. They enter their password, and the tool successfully recovers the file.

If a website claims to be a free or cheap online LabVIEW VI password recovery tool where you upload your .vi file and get the password back instantly, How LabVIEW Password Protection Works
Several unofficial tools and methods have been developed by the community to address lost passwords:
When you search for an "online LabVIEW VI password recovery tool," you will find two types: legitimate hash extractors for old VIs, and scams for new VIs.
Many sites advertising "free online password crackers" are fronts for malicious activity. They may require you to download a "helper utility" or an executable client to finish the decryption. These files frequently contain malware, ransomware, or trojans designed to infect your engineering workstation. 3. Lack of Support for Modern Formats online labview vi password recovery tool
Modern iterations of LabVIEW utilize much stronger cryptographic algorithms (such as salted hashes and standard AES encryption). The actual block diagram data is encrypted. Without the correct password to derive the decryption key, the block diagram is just unreadable, scrambled binary data.
A：正规的在线工具和GitHub项目通常采用“生成新文件”而非直接覆盖原文件的策略，原文件的安全性有一定保障。建议用户在处理前 务必手动备份原始文件 。
Older versions of LabVIEW used relatively weak, proprietary hashing algorithms. The password hash was stored directly within the binary structure of the .vi file. Because the security was basic, early desktop utilities could easily extract or bypass the hash.
Online tools offer instant, automated recovery, allowing you to bypass the need to install complex desktop software. Do you have access to the or documentation
Most online tools feature a "Drag & Drop" interface, allowing anyone to unlock a VI in seconds. Best Practices for Choosing an Online Tool
Always run unfamiliar recovery software inside a secure, isolated Virtual Machine (VM) disconnected from the network. 3. Contacting National Instruments (NI) Support
Look at the VI’s icon, connector pane inputs, and outputs.
