Free Download XML Signer v6.3 DC 22.01.2026 + Keygen

XML Signer is able to digitally sign your XML files using a digital certificate (X.509). Many individuals and organizations can benefit from this tool, as it provides fast and easy XML signature verification. It takes just one batch with XML Signer to sign a whole folder of XML files — this saves a lot of time when handling numerous files.

The software works seamlessly with all PKI systems and supports digital certificates issued from smart cards, USB flash drives, and other sources. Because XML Signer follows XAdES-BES, XAdES-BASELINE-B, and XMLDSig, both software and legal systems worldwide can use its signatures. It also backs up-to-date, safe algorithms for hashing, such as SHA-256 and SHA-512.

XML Signer works independently, so you do not need to purchase additional software unless you wish to. The certificate supports eIDAS (used throughout the EU) and is compatible with Windows 7 and later, which includes both Windows 11 and Windows Server 2022. XML Signer makes signing your XML documents with your digital certificate fast, secure, and straightforward if you already own one.
