I am new to encryption of messages but decided to give it a go. i made an algorithm that checks every letter in the message. for ever letter it finds it's position in the alphabet-(z) which is then used to match up to a scrambled up version of the alphabet. whatever character is at z of the scrambled up list is then used in the encoded message. to make it more secure i made the algorithm use a pincode. the scrambled up list shifts based on each number in the pincode.
Somebody then told me that computers would have no problem decoding a message encrypted like that. So I was wondering what the community thought. Would an algorithm like that be easily decrypted / bruteforced?
Here is an example of an encrypted message by my program:
VfP49NxMNx NfNZxMMZ9N4xMNMCCN9f PNMCNQ9hCQ9.
(i hope that helps to see if it easily decoded or not)
Thanks to anyone who could tell me!
