Microsoft AES Cryptographic Provider - Win32 apps (2024)

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

WindowsXP: The Microsoft AES Cryptographic Provider was named Microsoft Enhanced RSA and AES Cryptographic Provider (Prototype).

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 even though newer versions of this provider have been shipped. To determine the version of the provider in use, call CryptGetProvParam with the dwParam parameter set to PP_VERSION. Version 2.0 is in use if 0x0200 is returned.

The following table highlights differences between the Base Provider, Strong Provider, and AES Provider. The key lengths shown are the default key lengths.

For a complete list of supported algorithms, see AES Provider Algorithms.

The Strong Provider, Enhanced Provider, and AES Provider are backward-compatible with the Base Provider except that the providers can generate only RC2 or RC4 keys of default key length. The default length for the Base Provider is 40 bits. The default length for the AES Provider is 128 bits. Thus the AES Provider cannot create keys with Base Provider-compatible key lengths. However, the AES Provider can import RC2 and RC4 keys of up to 128 bits. Therefore, the AES Provider can import and use 40-bit keys generated by using the Base Provider.

What is the default cryptographic service provider in Windows? ›

The Microsoft Strong Cryptographic Provider is used as the default RSA Full cryptographic service provider (CSP). It supports all of the algorithms of the Microsoft Enhanced Cryptographic Provider and all of the same key lengths.

Should I use RSA or AES? ›

Securing file storage: AES is preferable due to its faster encryption and decryption speeds, making it suitable for encrypting large amounts of data. Secure communications: RSA is typically used for key exchange in SSL/TLS protocols, ensuring a secure channel for data transmission between clients and servers.

What is Microsoft AES? ›

Advanced cryptography

Microsoft AES keyboards use Microsoft Windows CryptoAPI, which is the same cryptographic resource found in Microsoft Windows Server products in government and corporate datacenters worldwide.

What are cryptographic services used for? ›

Definitions: A service that provides confidentiality, integrity, source authentication, entity authentication, non-repudiation support, access control and availability (e.g., encryption and decryption, and digital signature generation and verification).

What are the 4 cryptographic services? ›

Cryptographic Services includes ICSF, PKI Services, OCSF, and System SSL, and provides cryptographic functions for data secrecy, data integrity, personal identification, digital signatures, and the management of cryptographic keys.

What cryptocurrency does Microsoft use? ›

Top up your Microsoft account using BTC, BCH, ETH, USDC, and more. Under “Payment & billing”, select “Payment options”.

What is the Windows cryptographic service provider? ›

In Microsoft Windows, a Cryptographic Service Provider (CSP) is a software library that implements the Microsoft CryptoAPI (CAPI). CSPs implement encoding and decoding functions, which computer application programs may use, for example, to implement strong user authentication or for secure email.

Can I disable Cryptographic Services? ›

Step 1: Open the Services application again. Find the Cryptographic Services and select it. Step 2: Choose Properties and select Disabled from the Startup type box. Step 3: Restart the computer.

How to verify the Cryptographic Services are enabled? ›

1: Make sure your cryptography services are enabled. To do this, go to my computer | manage | services and applications | services. Then go to cryptography services properties and make sure the service is started and startup type is set to automatic. 2: If you are running Windows on a FAT32 drive, run scandisk.

What is the use of cryptographic security services? ›

It helps to reduce cyber attacks, thus increasing the availability of data. It provides various techniques for secure communication between users and devices. It helps to protect sensitive information from misuse, unauthorized access, etc. It ensures the confidentiality and integrity of the data.

What do you mean by cryptography services? ›

Cryptography ensures confidentiality by encrypting sent messages using an algorithm with a key only known to the sender and recipient. A common example of this is the messaging tool WhatsApp, which encrypts conversations between people to ensure they cannot be hacked or intercepted.

What is Microsoft enhanced security? ›

Enhanced security mode in Microsoft Edge mitigates memory-related vulnerabilities by disabling just-in-time (JIT) JavaScript compilation and enabling additional operating system protections for the browser. These protections include Hardware-enforced Stack Protection and Arbitrary Code Guard (ACG).

Does Microsoft use RSA? ›

RSA Partners with Microsoft to Secure Environments through New External Authentication Methods Capability. BEDFORD, MA—May 2, 2024—RSA, the security-first identity leader, announced that it is bolstering Microsoft environments through a continuing partnership that brings additional security to Office environments.

What is RSA in cryptography network security? ›

Rivest Shamir Adleman (RSA) is a well-known public-key or asymmetric cryptographic algorithm. It protects sensitive data through encryption and decryption using a private and public key pair.
