Abstract
In a method for controlling access to an encrypted document, a request to access the encrypted document is received. The access request includes a user ID and a user password. A one-way hash function is performed on the user password to generate a hash value. An access control table is searched for the hash value which indicates an authorization for the user to access the encrypted document. The hash value corresponds to a document password encrypted with the user password. The document password is decrypted using the user password. The encrypted document is decrypted using the decrypted document password.
