Encryption/Decryption

Two functions, Encrypt & Decrypt are needed. They must both allow a password to be specified and the encryption must be based upon that password. (eg give a different result depending on the password used). Then only the same password should be valid when in decryption. This must be totally secure. When you give us the functions we will encrypt something and have someone attempt to crack it. If they succeed at cracking it (in less than 24 hours), we cannot pay you as it is useless to us. ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Installation package that will install the software (in ready-to-run condition) on the platform(s) specified in this bid request. 3) Complete ownership and distribution copyrights to all work purchased. ## Platform Windows 95+ ## Deadline information It MUST be secure.
