This study analyses contemporary cryptographic and steganographic approaches to information security. During the analysis of symmetric and asymmetric cryptographic algorithms in combination with spatial and frequencydomain steganographic methods, it was observed that the use of a hybrid crypto-steganographic approach produces a synergistic effect, resulting in improved overall information protection compared to the use of individual mechanisms. Based on this analysis, a novel solution for implementing multi-level protection of confidential information transmitted over open communication channels is proposed. The proposed approach is based on the AES block cipher with optional RSA and ECC algorithms for symmetric key encapsulation, combined with a steganographic mechanism that utilises a marker embedded after the main content of the container. As part of the practical contribution, the proposed algorithm was implemented as a software module in the Python programming language. The developed crypto-steganographic system is versatile, as it enables secure encryption and concealment of data across a wide range of file types and formats. The obtained results may be applied in both scientific research and real-world information and communication systems
