Hello i want to implement AES algorithm. I have already implemented .net inbuilt algorithm. but it returns result in all aphanumeric. i want only hash value result the result should be in 0-9 A-F.

Please help me. I need it in C#.

Thanks

As far as I know AES is a symmetric cryptography that can encode text to cipher text and decode cipher text to its original form using key (authenticity/privacy). Hashing on the other hand is hashing algorithm that checks the integrity of your data. For my opion you're most likely talking about encoding(base16 0-1 A-F) rather than hash. well it's just my opinion.

Not a correct question. You say "I want to implement AES algorithm", but as far as you explanation goes, you need already written AES algorithm. This is not the same.

I am not sure what you have done, or are trying to do - as mentioned in the comments, AES is an encryption algorithm, not a hashing algorithm. However, regardless of which you need to use look at the Convert.ToBase64String Method[^] which will change the output to a "readable" string.

You may also need the Convert.FromBase64String Method[^] to reverse the process.

I want to implement AES algorithm which returns cipher in hash value
for e.g
key = 00000000000000000000000000000000
input = 6a84867cd77e12ad07ea1be895c53fa3
output/ciphertext should be 732281c0a0aab8f7a54a0c67a0c45ecf

but microsoft inbuilt algorithm returns ciphertext like this for same key and input :
igiHepR/GMYh7QCFGEnJBiqx65u0rx9WrBNERTNsN2qvlU2BP+t6bte2P4ApsKwt

the value is in alphanumeric field i want just between 0-9 A-F(hex)

Then look at the base64 conversion methods: I still think you are confused about what you are doing.
What are you actually trying to do with this information? Why are you using AES with a empty key?

This is my clent's requirement he want this type of algorithm

To do what? Sometimes the client must be educated as well... :laugh:
