Extract text from SigzaLock encrypted files (SGZ)
To convert SGZ encrypted files to another format, you need SigzaLock or other Encoded software.
To convert other file formats to the "Encrypted Data Vault" file type, you need software like SigzaLock or a similar tool.
An .SGZ file is a proprietary encrypted container created to securely store sensitive data. It was primarily developed as a digital vault for everyday files, such as DOCX documents or JPG images, locking them away from unauthorized access. To open it, users historically relied on SigzaLock, an encryption software suite that is now entirely discontinued. You can read more about file Encryption on Wikipedia to understand the underlying mechanics.
The biggest disadvantage of the .SGZ format is its total reliance on dead software. Because Sigza Authentication Systems discontinued the tool in 2014 and transitioned to the SAFE extension, opening these legacy archives on modern operating systems is a massive challenge. The proprietary nature of the format means there are no modern workarounds or native browser viewing options. Users need to migrate away from this format because relying on unsupported encryption tools inevitably leads to permanent data loss. If you possess the original password and software, your best course of action is to decrypt the payload and immediately convert it to universally supported, open formats like PDF or ZIP.
Converting an .SGZ file directly is inherently difficult because standard online converters cannot bypass encryption without the correct cryptographic keys. Often, only the original SigzaLock software can properly read or export the data. If our analysis detects a supported underlying or embedded format, viewing or conversion may still be possible. We can also quickly verify if the file is a misidentified or renamed GZ archive, saving you hours of troubleshooting.
Convert.Guru analyzes your SGZ file, detects the exact format, and lets you read the text inside.
If you want to convert SGZ file to , you can use SigzaLock or similar software from the "Legacy File Encryption Archive" category. In the File menu, look for Save As… or Export….
To convert files to SGZ, try SigzaLock or another comparable tool in the "Legacy File Encryption Archive" category.
The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our SGZ converter.
