Steps to make MySQL database:

Create DATABASE safemail; use safemail;

create table Message ( messageId varchar(256) PRIMARY KEY, prvKey varchar(2048) NOT NULL, messageKey varchar(2048) NOT NULL, question varchar(1024) NOT NULL, answer varchar(1024) NOT NULL ); ERROR 1071 (42000): Specified key was too long; max key length is 767 bytes

Changed messageid to 255 bytes to avoid that error.

mysql> create table User (userId varchar(255) PRIMARY KEY, pubKey varchar(2048) NOT NULL, prvKey varchar(2048) NOT NULL);

mysql> create table Message (messageId varchar(255) PRIMARY KEY, prvKey varchar(2048) NOT NULL, messageKey varchar(2048) NOT NULL, question varchar(1024) NOT NULL, answer varchar(1024) NOT NULL);
