I have a betting type site where I publish a number (between 0-100) that is encrypted. Then after a period of time, I would review what the number is and prove it with a key to decrypt the encrypted number to prove that I'm not cheating. I also want it to be easily verifiable by an average user.  What encryption algorithm/technique/package should I use?I'm no expert on cryptography. There seems to be so many options out there and I'm not sure what to use. python friendly is a plus.
What encryption algorithm/package should I use in a betting game?
python;encryption
Use AES.. see Comparison of DES, Triple DES, AES, blowfish encryption for data for details..As for ease of use.. refer you users to a Site Like: http://www.everpassword.com/aes-encryptor
