JCA
This is a cryptographic algorithm written by me.
Inspiration
I've always wanted to create a cryptographic algorithm. So when I found golang, I said to myself now is the time to do it. So I started learning Go and created my cryptographic algorithm whilst doing so.
jca
The jca binary file can be used to encrypt and decrypt any file with the given key. To do so, you just need to execute the following commands.
Encryption
jca -in YOUR_INPUT_FILE -key YOUR_KEY_FILE -out YOUR_OUTPUT_FILE
If you want to use a custom number of encryption rounds you can do so by using the -rounds switch.
jca -in YOUR_INPUT_FILE -key YOUR_KEY_FILE -out YOUR_OUTPUT_FILE -rounds YOUR_ROUND_COUNT
Please note, that if you change the round count you need to do so for the decryption too.
Decryption
jca -in YOUR_INPUT_FILE -key YOUR_KEY_FILE -out YOUR_OUTPUT_FILE -decrypt
If you used a custom number of rounds for the encryption you need to use the -rounds switch.
jca -in YOUR_INPUT_FILE -key YOUR_KEY_FILE -out YOUR_OUTPUT_FILE -rounds YOUR_ROUND_COUNT -decrypt
jca-keygen
At this point, the jca-keygen supports keys of size 2048 bytes, 4096 bytes, 8192 bytes, 16384 bytes, 32768 bytes, 65536 bytes, 131072 bytes, and 262144 bytes.
To generate a key use:
jca-keygen -size YOUR_KEY_SIZE -out YOUR_OUT_FILE
If you don't specify the size the program is gonna use 8192 bytes by default.
jca-integrity
This tool generates the sha256 and md5 sums for a given file.
Attention
I might remove this tool in the future and add a decryption check to the cryptographic algorithm, that way it can check if the decryption was successful or not.
Dependencies
The binaries do not need any libraries. If you want to build the tool by yourself tho you need to install golang.
Ubuntu
sudo apt-get install golang
Windows
Go to the golang.org site and download the newest version.
Information for the interested
For my algorithm, I used the substitution box from AES, due to me being too lazy to make my own.
Issues
If you have any issues please specify examples like exit code and console output, no support if not given!!!
