Gets a value that indicates whether the specified algorithm is supported by this class.

- algorithm
- String
The cryptographic algorithm.
Returns
true when the specified algorithm is XmlDsigDSAUrl, XmlEncRSA15Url, XmlEncRSAOAEPUrl, XmlDsigRSASHA1Url, or RsaSha256Signature and the public key is of the right type; otherwise, false.
Remarks
The IsSupportedAlgorithm method returns true when one of the following is true:
The
algorithmparameter is XmlDsigDSAUrl and the public key for the X.509 certificate specified in the constructor is of type DSA.The
algorithmparameter is XmlEncRSA15Url, XmlEncRSAOAEPUrl, XmlDsigRSASHA1Url or RsaSha256Signature and the public key for the X.509 certificate specified in the constructor is of type RSA.
Due to collision problems with SHA1, Microsoft recommends a security model based on SHA256 or better.
