About SHSH files

.SHSH files are cryptographic digital signatures generated by Apple's signing servers. They are used exclusively to authorize iOS firmware restores on iPhones and iPads. Jailbreak enthusiasts use tools like TinyUmbrella or TSS Saver to save these SHSH blobs to downgrade devices to older, unsigned iOS versions. The main disadvantage of the .SHSH format is its highly proprietary and device-specific nature. Every file is cryptographically tied to a single device's ECID (Exclusive Chip ID). They are not standard data files, require specific jailbreak software to utilize, and are useless if not saved while Apple is actively signing the target firmware. You cannot traditionally convert an .SHSH file to an image or document. However, since the underlying structure is often an Apple Property List (PLIST) or XML, the best conversion targets are XML, PLIST, or standard TXT. Converting to these formats strips the cryptographic application but allows you to read the device identifiers and firmware data. Standard online converters fail to process .SHSH files because it is a closed, proprietary cryptographic format. Typically, only specialized software can read the data. If our analysis detects a supported underlying or embedded format, viewing or conversion may still be possible.

Convert.Guru analyzes your SHSH file, detects the exact format, and lets you read the text inside.

The SHSH Converter Story

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 SHSH converter.
