Similar to class CEncryption but simplified for function calls and no progress events.
|(Declarations)||Declarations||Declarations and private variables for the modEncryption module.|
|EncryptString||Procedure||Encrypt/Decrypt a string with XOR encryption with support for Unicode. The encrypted string produced by the method is
reversible. This means that if you encrypt a string, then encrypt the results of that operation, the original string is restored.
Note: The same password must be supplied to successfully decrypt the string. See the example tab for a demonstration of this. If you need an ASCII version of this function, use the EncryptStringAscii method.
|EncryptStringAscii||Procedure||Encrypt/Decrypt a string with XOR encryption, returning the result in ASCII format. The encrypted string produced by the
method is reversible. This means that if you encrypt a string, then encrypt the results of that operation, the original string is restored.
Note: The same password must be supplied to successfully decrypt the string. See the example tab for a demonstration of this. The EncryptStringAscii method returns the result in ASCII format. If you need to pass the results of the EncryptString function on the command line, or use it external to your program, it is recommended that you use the ASCII version of this function.
|EncryptByte||Procedure||Encrypt one byte, and modify the password. Modifying the password as we encrypt makes the encryption slightly harder to break.|
