WebNov 8, 2024 · Cryptographic operations in .NET Core and .NET 5+ are done by operating system (OS) libraries. This dependency has advantages: .NET apps benefit from OS reliability. Keeping cryptography libraries safe from vulnerabilities is a high priority for OS vendors. To do that, they provide updates that system administrators should be applying. WebAdvantages. The stored image file is completely secured, as the file is being encrypted not by just using one but three encryption algorithm which are AES, DES and RC6. The key is also safe as it embeds the key in image using LSB. The system is very secure and robust in nature. Data is kept secured on cloud server which avoids unauthorized access.
