Microsoft is banning certain cryptographic functions from new computer code, citing increasingly sophisticated attacks that make them less secure, according to a company executive.
Partner Resource Center The Redmond, Wash., software company instituted a new policy for all developers that bans functions using the DES, MD4, MD5 and, in some cases, the SHA1 encryption algorithm, which is becoming "creaky at the edges," said Michael Howard, senior security program manager at the company, Howard said.
MD4 and MD5 are instances of the Message Digest algorithm that was developed at MIT in the early 1990s and uses a cryptographic hash function to verify the integrity of data.
