- algorithm
- String
The hash algorithm.
Returns
A HashAlgorithm that generates hashes for digital signatures.
Exceptions
algorithm is not supported. The supported algorithms are XmlDsigDSAUrl, XmlDsigRSASHA1Url, and RsaSha256Signature.
Remarks
Use the XmlDsigDSAUrl, XmlDsigRSASHA1Url or RsaSha256Signature fields to specify the algorithm parameter.
Due to collision problems with SHA1, Microsoft recommends a security model based on SHA256 or better.
