The tool used for establishing an on-the-fly encrypted volume that requires no user intervention is VeraCrypt. This open-source disk encryption software allows users to automatically encrypt and decrypt data in real time without requiring manual input each time data is accessed. VeraCrypt is known for its ability to create encrypted volumes that can be mounted and accessed as if they were regular drives, while providing robust security features that protect data without imposing significant overhead on users. Its design encourages the seamless integration of encryption processes into everyday operations, minimizing interruptions and maintaining usability.

While TrueCrypt is a predecessor to VeraCrypt and offered similar functionality, it is no longer actively maintained and has known security vulnerabilities that discourage its use. BitLocker is specifically a feature available in certain versions of Windows that provides full disk encryption, but it is designed primarily for securing the entire operating system drive and is not inherently an "on-the-fly" volume creation tool in the same flexible manner as VeraCrypt. WinRAR, on the other hand, is primarily a file compression utility and offers limited encryption options, but it does not provide the capability to create encrypted volumes in the same way as VeraCrypt.
