answer:Fixed income markets globally experienced market fatigue after a strong performance in November. Weaker data from China and the EU was largely ignored. The market sold off after the release of lower PCE and higher continuing claims data. During the session, there were good flows in various sectors. In China, there was a flood of front end paper, while high beta assets remained quiet. In China HY, ETFs were net buyers of Macau, while China real estate remained weak. In sovereigns, there were constructive flows in frontier markets and a rally in rates across the IG space. In AT1s, there was buying interest from asset managers and private wealth.

answer:To handle the input requirements, you can modify the code as follows: 1. Handling plaintext size less than 8 characters: - Check the length of the plaintext. - If the length is less than 8, add special characters to the plaintext until it reaches a length of 8. 2. Handling plaintext size more than 8 characters: - Divide the plaintext into blocks of size 8. - Process each block separately. 3. Handling key size of 8 characters: - Check the length of the key. - If the length is not 8, display an error message and request another key from the user. For key generation: 1. Permutated choice 1: - Implement the permutation logic to generate the first permuted key. 2. Left shift: - Implement the left shift operation on the key. 3. Permutated choice 2: - Implement the permutation logic to generate the 16 subkeys. 4. Repeat step 2 and 3: - Repeat the left shift and permutated choice 2 operations to generate the remaining 15 subkeys. For encryption: 1. Initial permutation: - Implement the initial permutation logic. 2. 16 rounds: - Repeat the following steps 16 times: - Expansion: Implement the expansion logic. - XOR (key, result of expansion): Perform XOR operation between the subkey and the expanded input. - S-Boxes: Implement the logic to substitute the values using the S-Boxes. - Permutation: Implement the permutation logic. - XOR (result of permutation and left): Perform XOR operation between the result of permutation and the left input. - Left and Right swap: Swap the left and right inputs. 3. 32-bit swap: - Implement the logic to swap the left and right inputs. 4. Inverse initial permutation: - Implement the inverse initial permutation logic. By implementing the above modifications, you can handle the input requirements and perform key generation and encryption accordingly.
