I've just finished writing a new system and I'd like to see if and how people can crack it.

In this hypothetical situation with two people a and b, a sends a message to b and b sends a response to that message. Below is their brief conversation.

Message(a--->b)

hm3tbt?6t9m7tm75trm0t2n8tl41t b}t9ttp2thl4t
ot3thl8t%bh4t7o0tx_l3t9h7th &r9ttn1t7a3tbh5t

ll3t2m3tn/h6tzu0tbe8txt5|thm7t zr7tnp4to3$

Response(b--->a)

arntmn&oglrlt8mcoamatnr^mn err32rathr:bbxo5ghmbogto4wrlnm hctbtbtz\0hbgcath2b0o4at
trto93*totrtnp4bjf6tbotanhmhbm wo)970mtm;tttg6ntfmltltlbmbgbp rbo,arab0to7t1tth5b8

What is the message? And the response? What is the encryption system with all its conditions? What key was used?

Let me know if you manage to crack it and how long it took.

If you want anyone to evaluate your system, you should provide full details.

That is, a full description of the encryption and decryption processes, and source code for a working implementation in some widely-used programming language.

Plus several samples of plaintext/ciphertext/key.
