Microsoft Enhanced Cryptographic Provider

Windows Mobile 6.5
A version of this page is also available for
4/8/2010

The Microsoft Enhanced Cryptographic Provider, called the Enhanced Provider, supports the same capabilities as the Microsoft Base Cryptographic Provider, called the Base Provider. The Enhanced Provider supports stronger security through longer keys and additional algorithms. It can be used with all versions of CryptoAPI.

Cryptography Services with High Encryption Provider is FIPS 140-2, level 1 certified.

For more information about FIPS certification for Windows Mobile, and Windows Mobile Version 5.0 with the Messaging and Security Feature Pack (MSFP), see this Web site.

To maintain backward compatibility with earlier provider versions, the provider name, as defined in the Wincrypt.h header file, retains the version 1.0 designation. However, version 2.0 of this provider is also shipping. To determine the version of the provider in use, call CryptGetProvParam with the dwParam argument set to PP_VERSION. Version 2.0 is in use if 0x0200 is returned.

Provider Type: PROV_RSA_FULL

Provider Name: Microsoft Enhanced Cryptographic Provider v1.
