I admit under penalty of perjury -

This bid request is to test the security of the encryption algorithm developed by our company. We need to know whether the encryption module we developed for our use is as secure as we would like it to be or if it can be easily broken. We would like to engage the services of one or more coders to check the integrity and security of our encryption schema.

The coders will be given blocks of ciphertext of varying length, encrypted by our algorithm, using varying key lengths. The coders will then try to decrypt the ciphertext in order to obtain the plaintext. Please note that all the steps used in attempting to obtain plaintext have to be substantial and fully documented. In the event of a successful decryption of the encoded text, the procedure and techniques used for the hack have to be submitted to us.

Anyone attempting to work on this can contact us with their details/resume, including references to any similar work done previously.
