universal encoder/decoder reedosolomon

This library is a universal file encoder and decoder using Ridosolomon codes with error correction

It remembers which directories you use most frequently, so you can "jump" to them in just a few keystrokes.
zoxide works on all major shells.

Use as compiled file

Step 1: Clone repo

git clone https://github.com/mellanyx/reedosolomon.git

Step 2: Build project

Let's go to the cloned project and execute the following command:

go build

After that the compiled file will appear

Step 3: Applications

Encode file

./reedosolomon encode [file path] [primitive] [eccsybmols]

primitive poly GF(256) = one of (285, 299, 301, 333, 351, 355, 357, 361, 369, 391, 397, 425, 251, 463, 487, 501)

Number of bugs to be fixed = eccsybmols * 2

For example, if we specify eccsybmols equal to 2, then the maximum number of errors that we can fix will be 4.

Corrupt file

./reedosolomon corrupt [file path] [eccsybmols]

eccsybmols - we indicate a value no more than what we indicated during encoding. Once executed, the program itself will corrupt every 256 bits with an error count equal to (eccsybmols / 2)

Decode file

./reedosolomon decode [file path] [primitive poligon 285 / 301] [eccsybmols]

primitive poligon - we specify the same value as when encoding.

eccsybmols - we specify the same value as when encoding and corrupt.

After execution, we should get our original fully working file

Use as a library

Step 1: Import in your project

go get https://github.com/mellanyx/reedosolomon.git

package main

import "github.com/mellanyx/reedosolomon/functions"

Step 2: Usage

Encode file

primitive poly GF(256) = one of (285, 299, 301, 333, 351, 355, 357, 361, 369, 391, 397, 425, 251, 463, 487, 501)

Number of bugs to be fixed = eccsybmols * 2

For example, if we specify eccsybmols equal to 2, then the maximum number of errors that we can fix will be 4.

reedosolomon.EncodeFile(filepath, primitive, eccsymbols)

Corrupt file

eccsybmols - we indicate a value no more than what we indicated during encoding. Once executed, the program itself will corrupt every 256 bits with an error count equal to (eccsybmols / 2)

reedosolomon.CorruptFile(filepath, eccsymbols)

Decode file

reedosolomon.DecodeAndFixCorruptFile(filepath, primitive, eccsymbols)

primitive poligon - we specify the same value as when encoding.

eccsybmols - we specify the same value as when encoding and corrupt.

After execution, we should get our original fully working file

Testing on a 1GB file

Tested on MacBook Air 2020:

• Chip: Apple M1
• Shared memory: 16 GB
• SSD: 512 GB

Encode 1GB file
