Did neanderthals need vitamin C from the diet? in Python 3 and some tips ;). For instance, Let's understand how to URL encode the character @. Decode bytes-like object or ASCII string s using the URL- and filesystem-safe alphabet, which substitutes -instead of + and _ instead of / in the standard Base64 alphabet, and return the decoded bytes. The table index is the value in Instead, you can do this, So, something like: b'abc=' works just as well as b'abc==' (as does b'abc====='). Encoding.UTF8; var bytes = encoding.GetBytes(plainText); return Convert.ToBase64String(bytes); } } So you can call the EncodeBase64() extension method to encode a plain text to base64 string. The encoder does not add any line separator character. It appears this is exactly what I was looking for! However, in some cases, this level of obfuscation might be deemed sufficient. Since you gain access to individual AST nodes, using this approach allows you to perform arbitrary modifications to the source file. One major issue that jumped out at me, was that keyword parameters are not usable :( You must write function calls using positional parameters only.

The compiled binary was to be used for the HitB CTF and as such had strict obfuscation requirements. Got a strange string after encryption, how to concert it to a normal alphanumeric characters? offset 0. the extra space. Well need a verification function to check if characters are are valid for the Overview; LogicalDevice; LogicalDeviceConfiguration; PhysicalDevice; experimental_connect_to_cluster; experimental_connect_to_host; experimental_functions_run_eagerly If you want to convert byte array to string cutting off trailing '\x00' characters the following answer is not enough. It will decode the sets of 4 base64 characters into 3 bytes. encoding are the most common and use +/ as the last two characters. Is it possible to hide code in my importable package? I just want my bytes as hex! This should be expanded to handle newlines, deal with URLs in the world wide web can only contain ASCII alphanumeric characters and some other safe characters like hyphen (-), underscore (_), tilde (~), and dot (.). What are you trying to hide? Follow this link for further details about understanding and working Compile python source file to code object, Iterate code object, wrap bytecode of each code object as the following format. All supported programming languages have built-in mechanisms for base64 encoding content. I wasn't in love with that plan, so I added a fork from project, allowing you to import and utilize the tool from a library instead. It wraps an output stream for encoding byte data using the Base64 encoding scheme. Absolutly, as @TejasTank says. Sudo update-grub does not work (single boot Ubuntu 22.04).
