Yes No. Sorry this didn't help. Thanks for your feedback. Carlosda silva. Good Evening, I received a email and opened it , and found out it was an incription virus. The incription is RSA can someone help me removing this issue. This thread is locked. It is not recommended that you install MSE on an already infected computer.

Yes No. As such, we are further hardening our criteria for the RSA algorithm with key length less than bits. To further reduce the risk of unauthorized exposure of sensitive information, Microsoft has created a software update that will be released in August for the following operating systems: Windows XP, Windows Server , Windows Server R2, Windows Vista, Windows Server , Windows 7, and Windows Server R2.

This update will block the use of cryptographic keys that are less than bits. Some issues that you may encounter after applying this update may include:. To prepare for this update, you should determine whether your organization is currently using keys less than bits.

If it is, then you should take steps to update your cryptographic settings such that keys under bits are not in use. The Crypto API builds a certificate trust chain and validates that chain using time validity, certificate revocation, and certificate policies such as intended purposes. Once the update is applied, during chain building there is an additional check to ensure that no certificate in the chain has key length less than bits.

Chain building is done using the CertGetCertificateChain function. If a key chain building issue is encountered with such a certificate, then the errors produced are as follows: Event 11, CAPI2. There are three cryptographic service providers CSPs that default to allow minimum bit keys in Windows Server R When working with V2 certificate templates, if you do not specify the key size, then the default CSP with default key size will be used to generate the key. The CA which has been updated with weak key protection will reject such request.

As a result, we recommended that you do the following:. When using certreq , ensure that you specify a bit or larger key in the INF file. You can run the following query on your Certification Authorities CAs in order to discover certificate templates that are utilizing keys under bits:. If you run this query, templates that utilize keys that are smaller than bits will be shown with their key size.

The following figure illustrates that two of the built-in templates SmartcardLogon and SmartcardUser templates have default key lengths that have minimum key sizes of bits. You may also discover other templates that were duplicated with minimum key sizes of less than bits. Microsoft Localization.
