public string CreateSignature(byte[] data, UrlSigner.BlobSignerParameters parameters)

Synchronously signs the given blob.

Parameters
Name	Description
data	byte The data to sign. Must not be null.
parameters	UrlSignerBlobSignerParameters Parameters to use when deriving the signing key. Concrete implementations may allow a null value if no parameters are required.
