The sender acknowledges the receiver's understanding and execution of a decrypt function, affirming its correctness. Additionally, the discussion points towards a conceptual approach to decrypt functions, suggesting that viewing them merely as function calls could be more intuitive. This perspective contrasts with the traditional approaches taken in FE papers, which may diverge from this simplicity for a variety of reasons not specified in the email. The conversation underscores a nuanced appreciation of decryption methodologies within the context of field encryption studies, indicating a divergence in practical application and theoretical documentation.
