genecode-cr

Genecode XY is a command-line Caesar Cipher developed in Crystal which turns texts into DNA-RNA sections. You can use the command genecode-cr --encode "text here" to codify an ordinary text, or decode DNA-RNA coded texts like "TCTGCCUCGUCTGTUUGCAACTCTUATUATAUGUGA".

You will need a key to both encode or decode a text. Crypted texts have unique key, of course, but you can choose one from 0 up to 121 for encoding with --key option or leave it random by omitting it.

The wise says:

"This program is for you, those little nerds who want

to explore the beautiful amount of uselessness of talking

whith other little nerds like you in an imaginary language".

Are you not convinced yet? Give it a try and have fun!

Installation

Install crystal compiler.

Then:

git clone https://github.com/nin93/genecode-cr.git
cd genecode-cr
shards build --release --no-debug
# Optional: your binary is in bin/
sudo cp ./bin/genecode-cr /usr/local/bin/

Usage

genecode-cr [-l|-u|-w] [(-e|-d) [-k <KEY>] [TEXT1 TEXT2 ...]]

Multiple text are allowed.

Standard input is read if no TEXT is given:

$ echo "foo" "bar" | genecode-cr -e -k 11
TUCTCUTCUUGCTUGTACTTTGGTUAG

Encoding

You can encode a text without specifying the key, genecode-cr will provide it in that case.

$ genecode-cr --encode "I'm encoding with a random key!"
[key: 3]
AGUCACTTCUTATCTGAGTGCGATTCGTTGGAGTCUUTAGUCTTGGUTTCCUTATGAUTAGACTGAGAGTCGGATTTCUTATTATCTGGTUTUUGA

Every ASCII printable character is allowed, even newline char. For complete list type genecode-cr --list. You can nevertheless go ahead and skip text parsing by including --unsafe option.

NOTE: key shows up in standard error output.

Decoding

Decoding is as simple as encoding. You must provide a key in order to decode a text:

$ genecode-cr --decode -k 17 CTCUUATGTTAATAATATUUAATUUUATUUTAATTAUUUUAA
I need a key

Here text format is highly restricted and so do the error parsing, but you won't worry about that if texts come out from genecode-cr itself.

Error handling

Invalid characters will cause an exception raise.

$ genecode-cr -e "I'm a beautiful text" "but I can'ŧ handłe ev€ry cħaractær"
genecode-cr: Invalid characters for text to convert:
I'm a beautiful text
but I can'ŧ handłe ev€ry cħaractær
Program ended with exit code 16

Errors will appear in red:

Use --unsafe option avoid exception raising, but output might be broken:

• Encoding

$ genecode-cr -e --unsafe "I can'ŧ handłe ev€ry cħaractær"
[key: 46]

$ genecode-cr -d -k 46 UTGGATCTTCCCAUAGUUGATAATCCCAUACTACTUGATCTUACGAGTACUGATCTTCCCAGTCCCCTTAGUAGTUAG

• Decoding

$ genecode-cr -d --unsafe -k 59 UCCCTGCTGCTGCooopsTGCTGCTTCTCUAG
Uooo!!+%

It was:

$ genecode-cr -e -k 59 Uooooops
