WebThis method creates a digital signature that is verified using the VerifyHash method. The valid hash algorithms are SHA1 and MD5. The algorithm identifier can be derived from the hash name by using the MapNameToOID method. Due to collision problems with SHA1 and MD5, Microsoft recommends a security model based on SHA256 or better. See also
