How to Verify Digital Signature

Version 11.4 and above have digital signature.
  1. Download Ultrasurf program, unzip it if it is in zip format.
  2. Right click the program (for example, u1104.exe), select "Properties". There should be a tab "Digital Signatures".
  3. Select "Digital Signatures" tab, "Name of signer" should be "Ultrareach Internet Corp."
  4. Select this signature, and click "Details", you should see "This digital signature is OK." under "Digital Signature Information"
  5. Click "View Certificate", you should see "Issued to: Ultrareach Internet Corp." and "Issued by: GlobalSign CodeSigning CA - G2"
If any of the above step fails, please delete it and download again. If you still can not verify the digital signature correctly, you should discard the program.

How to Verify Old Versions

We strongly recommend users to use the latest version and verify the digital signature, for best support and security. In case users still use an old version, please verify the SHA1 and MD5 of the exe file before use, and upgrade to the latest version as soon as possible. If your version is not listed here, please do not use it.
