I've got an encryption module used in a system I can't change. The module does some byte ordering etc. and uses then Speck cipher with PCBC mode (not implemented in Java codes I found by quick search) We're working on a Java service to communicate with these, so I would need a compatible implementation in Java. Attached is a Python code that contains the code. I need the encrypt_message() and decrypt_message() that are fully compatible with these, so a few unit tests with different message lengths are needed. Delivery scope: 1. Compatible Java code in a class or two (may use BSD/MIT/Apache licensed code, as long as no large external dependencies are needed). 2. Unit tests with 1, 4, 8, 64 byte payloads for both Python and Java (create encrypted message with Python code and use those in Java unit tests). To filter necessary expertise and autobidding bots: what is PCBC mode in this context ?

Hello, The PCBC mode is in this context the mode with which the block cipher encrypts the data. In particular in this mode a block of the plaintext is encrypted by first xoring it with an other message and then encrypting it with the speck cipher. The message to xor with is for the block a (generaly randomly chosen) initialization vector and for every other block this message is the plaintext of the previous block xored with the ciphertext of the previous block. I have experience in Python and Java programming.
