Moved to the appropriate forum, as the Developer General Discussion forum very clearly states:

@dakotadevada I really don't know what bugging you, but I use HTML reports in AutoIt. It gives me the power to draw HTML reports, including SVG images and scalable content. All you have to do is display the .html file.

As to your original question about decrypting executables? I think you are the only person with any comprehension as to what you think that question entails.

To encrypt or decrypt files , AutoIt offers the following functions (you probably already found them yourself).

Decrypts a file with specified key and algorithm : _Crypt_DecryptFile

Encrypts a file with specified key and algorithm : _Crypt_EncryptFile

At runtime, the program/script must be present in an unencrypted form so that the interpreter can execute it.

Sensitive data (passwords etc.) should not be stored in the source code anyway. It also doesn't matter much whether you use the format .au3 (clear code), .a3x (tokenized code) or .exe ('compiled' , a3x plus interpreter).

.a3x and .exe may provide minimal protection against DAUs, but nothing to rely on.

Note : The following project from @RTFC might be of interest to you : codecrypter-encrypt-your-script

i know HTML + AutoIT isn't popular, so there isn't much information on it.

I'm afraid I don't know what exactly your goal is, since AutoIt+Html was not part of your initial question. A quick search on "autoit html report" reveals some hits that are quite useful, e.g. _array2htmltable

I agree with that. The use of Html (depending on the task) can allow a very flexible implementation. Another approach would be e.g. the use of the Excel UDF from @water. However, for a detailed assistance we need more precise background information.
