## RSACng now correctly loads RSA keys of non-standard key size
|
||
|
|
|
||
|
|
### Scope
|
||
|
|
Edge
|
||
|
|
|
||
|
|
### Version Introduced
|
||
|
|
4.6.2
|
||
|
|
|
||
|
|
### Source Analyzer Status
|
||
|
|
Planned
|
||
|
|
|
||
|
|
### Change Description
|
||
|
|
In .NET Framework versions prior to 4.6.2, customers with non-standard
|
||
|
|
key sizes for RSA certificates are unable to access those keys via the
|
||
|
|
`GetRSAPublicKey()` and `GetRSAPrivateKey()` extension methods. A
|
||
|
|
`CryptographicException` with the message "The requested key size is
|
||
|
|
not supported" is thrown. In .NET Framework 4.6.2 this issue has been
|
||
|
|
fixed. Similarly, `RSA.ImportParameters()` and
|
||
|
|
`RSACng.ImportParameters()` now work with non-standard key sizes
|
||
|
|
without throwing `CryptographicException`'s.

|
|
|
||
|
|
### Recommended Action
|
||
|
|
If there is any exception handling logic that relies on the previous
|
||
|
|
behavior where a `CryptographicException` is thrown when non-standard
|
||
|
|
key sizes are used, consider removing the logic.
