Hi everybody. I'm adding Md5 hashcode security to my users passwords. but I'm getting the following error: anonymous wrote : | ERROR [Util] Password hash calculation failed | java.security.NoSuchAlgorithmException: MD5­ MessageDigest not available | Everytime I login. My code is: <login-module code = "org.jboss.security.auth.spi.DatabaseServerLoginModule" | flag = "required"> | <!--<module-option name = "unauthenticatedIdentity">guest</module-option>--> | <module-option name = "dsJndiName">java:/woneview</module-option> | <module-option name = "principalsQuery">SELECT password FROM bu_usuario WHERE username=?</module-option> | <module-option name = "rolesQuery">SELECT rol, 'Roles' FROM bu_roles WHERE username=?</module-option> | | <module-option name = "hashAlgorithm">MD5­</module-option> | <module-option name = "hashEncoding">base­64</module-option> | | </login-module> | I think I forgot to add something to the jboss path, but I have not found any information.
