Extract text from SIGNATURE files
To convert your SIGNATURE file to another format, you need Xcode or other System software.
To convert other file formats to the "Cryptographic Signature File" file type, you need software like Xcode or a similar tool.
The .signature file extension serves two distinct but technical purposes: a cryptographic detached signature (commonly associated with PKCS#7, Apple Xcode, or email security) or an XML-based authentication file used by the India Income Tax Department.
In the context of cryptography, a .signature file is not a document you read; it is a mathematical proof. It contains a hash of another file encrypted with a private key, ensuring that the original data has not been tampered with. Users commonly have issues here because they attempt to "open" the signature file expecting to see the contract, software, or email content it protects. Instead, they are met with binary noise or Base64-encoded text. This file requires the original data and a verification utility (like OpenSSL) to be useful. It is structurally similar to P7S or SIG files.
Alternatively, for Indian taxpayers, this file is an XML generation from the Income Tax e-Filing Utility. While it contains critical tax data, it is formatted for machine processing, not human reading. Users frequently need to convert these files to PDF for archiving or TXT to inspect the raw XML structure without relying on the proprietary Java utility. For general handling, converting a .signature file to TXT allows you to view the headers and determine if it is a standard PEM-encoded certificate or an XML dataset.
Convert.Guru analyzes your SIGNATURE file, detects the exact format, and lets you read the text inside.
Users also converted JPEG, JPG, PKPASS, JSON, PNG, PDF, DOCX, JFIF, ZIP, BIN, PLIST, STRINGS and NIB files.
If you want to convert SIGNATURE file to PNG, HTML, JPG or BLACK, you can use Xcode or similar software from the "Digital Identity Verification" category. In the File menu, look for Save As… or Export….
To convert files to SIGNATURE, try Xcode or another comparable tool in the "Digital Identity Verification" 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 SIGNATURE converter.
