Abstract: The article presents a solution to the problem of not recognizing the O’zDst 1092:2009 algorithm by the operating system and the problem of using digital certificates generated using the O’zDst 1092:2009 algorithm and O’zDst 1106:2009 algorithm. These algorithms were adopted in 2009. But these algorithms are still not recognized by the operating system. For other cryptographic algorithms used in Windows, cryptographic service providers have been developed that provide cryptographic operation functions to other software. These cryp-tographic service providers do not support the above algorithms. From here it becomes necessary to develop the cryptographic provider supporting the O’zDSt 1106:2009 hashing algorithm and the O’zDSt 1092:2009 signature algorithm. But to work with digital certificates, one cryptographic provider is not enough. Special extensions are also required to encode and decode digital certificate data. Therefore, the development of an extension for cryptographic providers is given. Also, for managing digital cer-tificates and key lifecycle, a method of integrating cryptographic providers with Windows Active Directory Certificate Services is presented. Developed cryptographic providers are composed of 3 types of providers such as hash provider, signature provider, and key storage provider. The architecture of the key storage provider, a method for secure storage of cryptographic keys, as well as key access control are proposed. The description of the O’zDst 1092:2009 algorithm and the implementation of the functions of the Key storage provider interface are shown.
