For Linux and macOS users: Twenty Crypt does not automatically have executable permissions allowed. Run the following command before using Twenty Crypt:
chmod +x twce twcdHow to Use
Twenty Crypt comes with a few things: twce (Text Encoder), twcd (Text Decoder), and the Microsoft .NET 6 Runtime components that make Twenty Crypt a standalone .NET app.
From your command line, type the following:
twce "the twenty sentences" "2007131320"On Windows, it's the exact same thing:
twce "the twenty sentences" "2007131320"Put quotes around the string to make sure the cipher gets the entire string. Also, put quotes around the key for good measure.
If typed correctly, your output should look like this:
twce "the twenty sentences" "2007131320"

Original text: the twenty sentences
Encoded text: TWxSNHQxNGhiYm1SUWNvNT11NTN5SGV6R0tjaQ==
Write down the key to remember it.the twenty sentences is encoded into TWxSNHQxNGhiYm1SUWNvNT11NTN5SGV6R0tjaQ==. Now, you may think this is a plain Base64 string. However, when you decode the Base64 string normally, you'll get MlR4t14hbbmRQco5=u53yHezGKci. That doesn't look like a valid Base64 string to me. However, this cipher does not guarantee secure data encryption.
Each string sent to the program is separated into segments of twenty characters. If a segment is less than twenty characters, spaces are added to the end until the segment is twenty characters long.
Initial string less than twenty characters:
twce "the twenty sentence" "2007131320"

twcd "TWxSNHQxNGhiYm1SUWNvNT11NTN5SGV6R0tjaQ==" "2007131320"The output should be:
twcd "TWxSNHQxNGhiYm1SUWNvNT11NTN5SGV6R0tjaQ==" "2007131320"

Decoded text: the twenty sentencesThere you go, that's how the encoder and decoder work. The inputted string must be a multiple of 40 characters and contain valid Base64 strings.
Initial string with multiple Base64 strings:

Decoded text: the twentieth sentenceKey Syntax
The key is a ten digit string, holding five two-digit values. Let's look at the key from the previous examples: 2007131320
- 20 - A number between 1 and 25
- 07 - A number between 1 and 19
- 13 - A number between 1 and 27
- 13 - A number between 1 and 27
- 20 - A number between 1 and 25
Any value that is out of these bounds will not be accepted by the program, and text will not be encoded or decoded. Also, single digit numbers must have a leading zero to fit the value format, seen in the second example value (07).
