SSL root certificates for Windows Phone OS 7.1

Article
05/20/2016

[ This article is for Windows Phone 8 developers. If you’re developing for Windows 10, see the latest documentation. ]

The following tables list all certificate authorities (CAs) and their root certificates that are pre-installed on a Windows Phone. Each table heading includes a CA name and a current country or region. This is the main country or region from which the CA operates. The CA name is the current operator of the root certificate, which includes a root name, a unique thumbprint, and a root expiration date. These tables are a snapshot of ownership, as the ownership of a CA root certificate can change over time.

Important Note:
The root certificates discussed here apply only to Windows Phone OS 7.1. In Windows Phone 8, the list of root certificates is identical to and automatically synced with the root certificates supported by Windows 8. For the full list of supported Windows Phone 8 root certificates, see Windows and Windows Phone 8 SSL Root Certificates.

The information provided about root certificates is reproduced to the best of Microsoft’s knowledge; its accuracy is not warranted or guaranteed in any way. To confirm actual root certificate details, go to a CA's website.

Note

The Windows Phone and CE Root Certificate Program is not the same as the Windows Root Certificate Program. For more info about how to apply to the Windows Phone and CE Root Certificate Program, send an email to medroot@microsoft.com.

This topic contains the following sections.

Definitions

Term	Definition
CA Root Name	The common name applied to the root certificate, which might or might not also indicate the name of the CA.
CA Root Size	The modulus of the Rivest, Shamir, and Adleman (RSA) algorithm (typically 2048-bit or 4096-bit RSA). You might see references to other algorithms such as Elliptic Curve Cryptography (ECC) or Elliptic Curve Digital Signature Algorithm (ECDSA).
Signature Hash	The hash algorithm chosen by the CA for this root certificate – Message Digest Algorithm 2 (MD2), Message Digest Algorithm 5 (MD5), Secure Hash Algorithm 1 (SHA1), or SHA2 (SHA256). The hash algorithm used to issue end-use certificates might not be the same as the hash algorithm used for the root certificate.
CA Root Expires	The expiration date of the root certificate, after which the CA cannot issue any more end-use certificates from it. Root certificates are typically kept in distribution after expiration by the Windows Phone and CE Root Certificate Program until the last of these end-use certificates expire.
Thumbprint	The hash value which uniquely identifies the root certificate in question. It can be confirmed in the actual root certificate by examining the certificate properties under the Thumbprint field.
