Ghettocrypt CLI

Easy text and file encryption via the command line using Ghetto Crypt. Now supporting esoteric data formats... :)
Again, please only use this as an obfuscator or if the only other option would be no encryption at all. Do you want to quickly and securely encrypt stuff via the command line? Use openssl-cli with the aes cipher. It's a bit more wordy but much faster and more secure.

Still want to use Ghetto Crypt cli? Here ya go! Either download the latest release, or directly from here: gecrypt.

If you want to use this globally, you could move it to /usr/bin/, or some other location in your $PATH.

How do i use this?

--iobase-8   VOID   incompatibilities=[--iobase-2, --iobase-10, --iobase-64, --iobase-uwu, --iobase-ugh]   Interpret and format ciphertexts in base8

--progress   -p   VOID   Print digestion progress to stdout. May be advisable for large files, as the cipher is rather slow.

--cli-version   VOID   Will supply the version of ghettocrypt-cli used.

Examples

Please note that commonly used arguments are supplied in their short form (-e in place of --encrypt).

I want to encrypt text!

$ gecrypt -e --keyask --intext "hello, world!"
efbebc429c8370bf84f00b0d8ccbaf7858b3b87d71ff58cb1cfefa8fb0c68094c0865565873aa8a5254ede59be46e81a4d4917e679b18cb290dbd6669cb6207a

Now decrypt it

$ gecrypt -d --keyask --intext "efbebc429c8370bf84f00b0d8ccbaf7858b3b87d71ff58cb1cfefa8fb0c68094c0865565873aa8a5254ede59be46e81a4d4917e679b18cb290dbd6669cb6207a"
hello, world!

I won't be pasting in complete ciphertexts anymore here. I will abbreviatre them as efbebc...b6207a. This way it just looks tidier.

What about not using hex?

$ gecrypt -e --keyask --intext "hello, world!" --iobase-2
111001001011100000011111000100010100110011100110000100100101001001110001001000101011110000000011011100001010111010001000110111110110011011100000001100110001001000100111011000101010010001011011111011001000011111100100101001011110011101110001010011000101011001111010000001001100101110000101101101101001110100100001101010111101010000100111101110000110011101100101101011000011101001000011010010011001111010001001101000101001100101010000100010111101101100010000000001001110010001001011001001011011010111001101000100

Passing the key as an argument

$ gecrypt -e --key "secretpassword" --intext "hello, world!"

⚠️ Some operating systems will log cli arguments! THIS WOULD BE THE ENTIRE KEY!

Using keyfiles

$ gecrypt -e --keyfile "dog.jpg" --intext "hello, world!"

⚠️ Some operating systems will log cli arguments! One might find your keyfile!

Encrypting files

$ gecrypt -e --keyask --infile "cat.jpg"

File cat.jpg.crypt will be created.

Encrypting files to a target file name

$ gecrypt -e --keyask --infile "cat.jpg" -o "encrypted_cat.jpg"

File encrypted_cat.jpg will be created.

Decrypting files

$ gecrypt -d --keyask --infile "cat.jpg.crypt"

File cat.jpg.crypt.plain will be created. It's contents match cat.jpg

⚠️ Since this is a block cipher, decrypted files may be tailpadded with a few nullbytes.

Decrypting files to a target file name

$ gecrypt -d --keyask --infile "cat.jpg.crypt" -o "decrypted_cat.jpg"

File decrypted_cat.jpg will be created. You can now open it again.

Encrypting large files takes time. How's the progress?

$ gecrypt -e --keyask --infile "cat.jpg" --progress

Something along the lines of Encrypting... (Block 200 / 1148 - 17.4216%) will be regularly, but not too often, printed to stdout.

What version am i running?

Depending on wether you want to know the GhettoCrypt version or the CLI's version, use either --version or --cli-version. It will print out a floating point number.

I want to stream the output of file en/decryption.

You can dump the binary result to stdout. In this example, we'll stream it into a jpg file, but you could stream it to whatever you'd like.

$ gecrypt -d --keyask --infile "cat.jpg.crypt" --ostdout > "decrypted_cat.jpg"

Esoteric data formats
