The primary function of a disassembler is to convert machine language into assembly language. Machine language consists of binary code that is directly understood by the computer's hardware, while assembly language is a human-readable representation of that binary code. Disassemblers take the bytecode of executable files and translate it into assembly instructions, making it easier for programmers and security analysts to understand the behavior of software. This process is crucial for various tasks like reverse engineering, malware analysis, and understanding legacy systems that utilize low-level programming.

Although converting assembly language into machine language and encrypting data are important functions in computing, they are not the role of a disassembler. Similarly, while debugging executable programs is a significant aspect of software development, it typically involves different tools and processes rather than disassembly specifically. Understanding the distinction between these functions clarifies the role of a disassembler in the context of computer programming and security analysis.
